  APT42, an Iranian state-sponsored cyber espionage actor, is using enhanced social engineering schemes to gain access to victim networks, including cloud environments. The actor is targeting Western and Middle Eastern NGOs, media organizations, academia, legal services and activists. Mandiant assesses APT42 operates on behalf of the Islamic Revolutionary Guard Corps Intelligence Organization (IRGC-IO). APT42 was observed posing as journalists and event organizers to build trust with their victims through ongoing correspondence, and to deliver invitations to conferences or legitimate documents. These social engineering schemes enabled APT42 to harvest credentials and use them to gain initial access to cloud environments. Subsequently, the threat actor covertly exfiltrated data of strategic interest to Iran, while relying on built-in features and open-source tools to avoid detection. In addition to cloud operations, we also outline recent malware-based APT42 operations using two custom backdoors: NICECURL and TAMECAT. These backdoors are delivered via spear phishing, providing the attackers with initial access that might be used as a command execution interface or as a jumping point to deploy additional malware. APT42 targeting and missions are consistent with its assessed affiliation with the IRGC-IO, which is a part of the Iranian intelligence apparatus that is responsible for monitoring and preventing foreign threats to the Islamic Republic and domestic unrest. APT42 activities overlap with the publicly reported actors CALANQUE (Google Threat Analysis Group), Charming Kitten (ClearSky and CERTFA), Mint Sandstorm/Phosphorus (Microsoft), TA453 (Proofpoint), Yellow Garuda (PwC), and ITG18 (

Poll Vaulting: Cyber Threats to Global Elections
(lien direct)
Written by: Kelli Vanderlee, Jamie Collier
  Executive Summary The election cybersecurity landscape globally is characterized by a diversity of targets, tactics, and threats. Elections attract threat activity from a variety of threat actors including: state-sponsored actors, cyber criminals, hacktivists, insiders, and information operations as-a-service entities. Mandiant assesses with high confidence that state-sponsored actors pose the most serious cybersecurity risk to elections. Operations targeting election-related infrastructure can combine cyber intrusion activity, disruptive and destructive capabilities, and information operations, which include elements of public-facing advertisement and amplification of threat activity claims. Successful targeting does not automatically translate to high impact. Many threat actors have struggled to influence or achieve significant effects, despite their best efforts.  When we look across the globe we find that the attack surface of an election involves a wide variety of entities beyond voting machines and voter registries. In fact, our observations of past cycles indicate that cyber operations target the major players involved in campaigning, political parties, news and social media more frequently than actual election infrastructure.   Securing elections requires a comprehensive understanding of many types of threats and tactics, from distributed denial of service (DDoS) to data theft to deepfakes, that are likely to impact elections in 2024. It is vital to understand the variety of relevant threat vectors and how they relate, and to ensure mitigation strategies are in place to address the full scope of potential activity.  Election organizations should consider steps to harden infrastructure against common attacks, and utilize account security tools such as Google\'s Advanced Protection Program to protect high-risk accounts. Introduction  The 2024 global election cybersecurity landscape is characterized by a diversity of targets, tactics, and threats. An expansive ecosystem of systems, administrators, campaign infrastructure, and public communications venues must be secured against a diverse array of operators and methods. Any election cybersecurity strategy should begin with a survey of the threat landscape to build a more proactive and tailored security posture.  The cybersecurity community must keep pace as more than two billion voters are expected to head to the polls in 2024. With elections in more than an estimated 50 countries, there is an opportunity to dynamically track how threats to democracy evolve. Understanding how threats are targeting one country will enable us to better anticipate and prepare for upcoming elections globally. At the same time, we must also appreciate the unique context of different countries. Election threats to South Africa, India, and the United States will inevitably differ in some regard. In either case, there is an opportunity for us to prepare with the advantage of intelligence.

From Social Engineering to DMARC Abuse: TA427\\'s Art of Information Gathering
(lien direct)
Key takeaways   TA427 regularly engages in benign conversation starter campaigns to establish contact with targets for long-term exchanges of information on topics of strategic importance to the North Korean regime.  In addition to using specially crafted lure content, TA427 heavily leverages think tank and non-governmental organization-related personas to legitimize its emails and increase the chances that targets will engage with the threat actor.   To craftily pose as its chosen personas, TA427 uses a few tactics including DMARC abuse in concert with free email addresses, typosquatting, and private email account spoofing.   TA427 has also incorporated web beacons for initial reconnaissance of its targets, establishing basic information like that the email account is active.   Overview   Proofpoint researchers track numerous state-sponsored and state-aligned threat actors. TA427 (also known as Emerald Sleet, APT43, THALLIUM or Kimsuky), a Democratic People\'s Republic of Korea (DPRK or North Korea) aligned group working in support of the Reconnaissance General Bureau, is particularly prolific in email phishing campaigns targeting experts for insight into US and the Republic of Korea (ROK or South Korea) foreign policy.   Since 2023, TA427 has directly solicited foreign policy experts for their opinions on nuclear disarmament, US-ROK policies, and sanction topics via benign conversation starting emails. In recent months, Proofpoint researchers have observed (Figure 1) a steady, and at times increasing, stream of this activity. While our researchers have consistently observed TA427 rely on social engineering tactics and regularly rotating its email infrastructure, in December 2023 the threat actor began to abuse lax Domain-based Message Authentication, Reporting and Conformance (DMARC) policies to spoof various personas and, in February 2024, began incorporating web beacons for target profiling.  It is this initial engagement, and the tactics successfully leveraged by TA427, which this blog is focused on.  Figure 1. Volume of TA427 phishing campaigns observed between January 2023 and March 2024.  Social engineering  TA427 is a savvy social engineering expert whose campaigns are likely in support of North Korea\'s strategic intelligence collection efforts on US and ROK foreign policy initiatives. Based on the targets identified and the information sought, it is believed that TA427\'s goal is to augment North Korean intelligence and inform its foreign policy negotiation tactics (example Figure 2). TA427 is known to engage its targets for extended periods of time through a series of benign conversations to build a rapport with targets that can occur over weeks to months. They do so by constantly rotating which aliases are used to engage with the targets on similar subject matter.   Figure 2. Example of TA427 campaign focused on US policy during an election year.  Using timely, relevant lure content (as seen in Figure 3) customized for each victim, and often spoofing individuals in the DPRK research space with whom the victim is familiar to encourage engagement, targets are often requested to share their thoughts on these topics via email or a formal research paper or article. Malware or credential harvesting are never directly sent to the targets without an exchange of multiple messages, and based on Proofpoint visibility, rarely utilized by the threat actor. It is possible that TA427 can fulfill its intelligence requirements by directly asking targets for their opinions or analysis rather than from an infection. Additionally, insight gained from the correspondence is likely used to improve targeting of the victim organization and establish rapport for later questions and engagement.   Figure 3. Timeline of real-world events based on international press reporting, side-by-side with Proofpoint observed subject lures.  Lure content often includes invitations to attend events about North Korean policies regarding international affairs, questions regarding topics such as how deterr Malware Tool Threat Conference APT 37 APT 43 ★★

## Snapshot Over the last year, the speed, scale, and sophistication of attacks has increased alongside the rapid development and adoption of AI. Defenders are only beginning to recognize and apply the power of generative AI to shift the cybersecurity balance in their favor and keep ahead of adversaries. At the same time, it is also important for us to understand how AI can be potentially misused in the hands of threat actors. In collaboration with OpenAI, today we are publishing research on emerging threats in the age of AI, focusing on identified activity associated with known threat actors, including prompt-injections, attempted misuse of large language models (LLM), and fraud. Our analysis of the current use of LLM technology by threat actors revealed behaviors consistent with attackers using AI as another productivity tool on the offensive landscape. You can read OpenAI\'s blog on the research [here](https://openai.com/blog/disrupting-malicious-uses-of-ai-by-state-affiliated-threat-actors). Microsoft and OpenAI have not yet observed particularly novel or unique AI-enabled attack or abuse techniques resulting from threat actors\' usage of AI. However, Microsoft and our partners continue to study this landscape closely. The objective of Microsoft\'s partnership with OpenAI, including the release of this research, is to ensure the safe and responsible use of AI technologies like ChatGPT, upholding the highest standards of ethical application to protect the community from potential misuse. As part of this commitment, we have taken measures to disrupt assets and accounts associated with threat actors, improve the protection of OpenAI LLM technology and users from attack or abuse, and shape the guardrails and safety mechanisms around our models. In addition, we are also deeply committed to using generative AI to disrupt threat actors and leverage the power of new tools, including [Microsoft Copilot for Security](https://www.microsoft.com/security/business/ai-machine-learning/microsoft-security-copilot), to elevate defenders everywhere. ## Activity Overview ### **A principled approach to detecting and blocking threat actors** The progress of technology creates a demand for strong cybersecurity and safety measures. For example, the White House\'s Executive Order on AI requires rigorous safety testing and government supervision for AI systems that have major impacts on national and economic security or public health and safety. Our actions enhancing the safeguards of our AI models and partnering with our ecosystem on the safe creation, implementation, and use of these models align with the Executive Order\'s request for comprehensive AI safety and security standards. In line with Microsoft\'s leadership across AI and cybersecurity, today we are announcing principles shaping Microsoft\'s policy and actions mitigating the risks associated with the use of our AI tools and APIs by nation-state advanced persistent threats (APTs), advanced persistent manipulators (APMs), and cybercriminal syndicates we track. These principles include: - **Identification and action against malicious threat actors\' use:** Upon detection of the use of any Microsoft AI application programming interfaces (APIs), services, or systems by an identified malicious threat actor, including nation-state APT or APM, or the cybercrime syndicates we track, Microsoft will take appropriate action to disrupt their activities, such as disabling the accounts used, terminating services, or limiting access to resources. - **Notification to other AI service providers:** When we detect a threat actor\'s use of another service provider\'s AI, AI APIs, services, and/or systems, Microsoft will promptly notify the service provider and share relevant data. This enables the service provider to independently verify our findings and take action in accordance with their own policies. - **Collaboration with other stakeholders:** Microsoft will collaborate with other stakeholders to regularly exchange information a Ransomware Malware Tool Vulnerability Threat Studies Medical Technical APT 28 ChatGPT APT 4 ★★

The recorded honeypot attack started with exploiting a misconfigured API server. The attackers preceded by gathering information about the cluster, checking if their cluster was already deployed, and deleting some existing deployments. They used RBAC to gain persistence by creating a new ClusterRole and a new ClusterRole binding. The attackers then created a DaemonSet to use a single API request to target all nodes for deployment. The deployed malicious image from the public registry Docker Hub was named to impersonate a legitimate account and a popular legitimate image. It has been pulled 14,399 times and 60 exposed K8s clusters have been found with signs of exploitation by this campaign. Analyst Comment: Your company should have protocols in place to ensure that all cluster management and cloud storage systems are properly configured and patched. K8s buckets are too often misconfigured and threat actors realize there is potential for malicious activity.

Trending Cyber News and Threat Intelligence Xenomorph V3: a New Variant with ATS Targeting More Than 400 Institutions (published: March 10, 2023) Newer versions of the Xenomorph Android banking trojan are able to target 400 applications: cryptocurrency wallets and mobile banking from around the World with the top targeted countries being Spain, Turkey, Poland, USA, and Australia (in that order). Since February 2022, several small, testing Xenomorph campaigns have been detected. Its current version Xenomorph v3 (Xenomorph.C) is available on the Malware-as-a-Service model. This trojan version was delivered using the Zombinder binding service to bind it to a legitimate currency converter. Xenomorph v3 automatically collects and exfiltrates credentials using the ATS (Automated Transfer Systems) framework. The command-and-control traffic is blended in by abusing Discord Content Delivery Network. Analyst Comment: Fraud chain automation makes Xenomorph v3 a dangerous malware that might significantly increase its prevalence on the threat landscape.

Trending Cyber News and Threat Intelligence Threat Analysis: Active C2 Discovery Using Protocol Emulation Part3 (ShadowPad) (published: October 27, 2022) ShadowPad is a custom, modular malware in use by multiple China-sponsored groups since 2015. VMware researchers analyzed the command-and-control (C2) protocol in recent ShadowPad samples. They uncovered decoding routines and protocol/port combinations such as HTTP/80, HTTP/443, TCP/443, UDP/53, and UDP/443. Active probing revealed 83 likely ShadowPad C2 servers (during September 2021 to September 2022). Additional samples communicating with this infrastructure included Spyder (used by APT41) and ReverseWindow (used by the LuoYu group). Analyst Comment: Researchers can use reverse engineering and active probing to map malicious C2 infrastructure. At the same time, the ShadowPad malware changes the immediate values used in the packet encoding per variant, so finding new samples is crucial for this monitoring.

Raspberry Robin works as a three-file infection: Raspberry Robin LNK file on an USB drive, Raspberry Robin DLL (aka Roshtyak) backdoor, and a heavily-obfuscated .NET DLL that writes LNKs to USB drives. Microsoft researchers analyzed several infection chains likely centered around threat group EvilCorp (aka DEV-0206/DEV-0243). Besides being the initial infection vector, Raspberry Robin was seen delivered by the Fauppod malware, which shares certain code similarities both with Raspberry Robin and with EvilCorp’s Dridex malware. Fauppod/Raspberry Robin infections were followed by additional malware (Bumblebee, Cobalt Strike, IcedID, TrueBot), and eventually led to a ransomware infection (LockBit, Clop). Analyst Comment: Organizations are advised against enabling Autorun of removable media on Windows by default, as it allows automated activation of an inserted, Raspberry Robin-infected USB drive. Apply best practices related to credential hygiene, network segmentation, and attack surface reduction.

Trending Cyber News and Threat Intelligence Hacker Pwns Uber Via Compromised VPN Account (published: September 16, 2022) On September 15, 2022, ride-sharing giant Uber started an incident response after discovering a data breach. According to Group-IB researchers, download file name artifacts point to the attacker getting access to fresh keylogger logs affecting two Uber employees from Indonesia and Brazil that have been infected with Racoon and Vidar stealers. The attacker allegedly used a compromised VPN account credentials and performed multifactor authentication fatigue attack by requesting the MFA push notification many times and then making a social-engineering call to the affected employee. Once inside, the attacker allegedly found valid credentials for privilege escalation: a PowerShell script containing hardcoded credentials for a Thycotic privileged access management admin account. On September 18, 2022, Rockstar Games’ Grand Theft Auto 6 suffered a confirmed data leak, likely caused by the same attacker. Analyst Comment: Network defenders can consider setting up alerts for signs of an MFA fatigue attack such as a large number of MFA requests in a relatively short period of time.

Fortinet.webp 2022-03-10 23:39:03 APT41 Compromised Six U.S. State Government Networks (lien direct) FortiGuard Labs is aware of a report that threat actor APT41 compromised at least six networks belonging to U.S. state governments between May 2021 and February 2022. To gain a foothold into the victim's network, the threat actor used a number of different attack vectors: exploiting vulnerable Internet facing web applications and directory traversal vulnerabilities, performing SQL injection, and conducting de-serialization attacks. The intent of APT41 appears to be reconnaissance, though how the stolen information is to be used has not yet been determined.Why is this Significant? This is significant because at least six U.S. state government systems were broken into and data exfiltration was performed by APT41 as recent as February 2022 In addition, a zero-day vulnerability in the USAHerds application (CVE-2021-44207) as well as Log4j (CVE-2021-44228), among others, were exploited in the attacksWhat's the Detail of the Attack?APT41 performed several different ways to break into the targeted networks.In one case, the group exploited a SQL injection vulnerability in a Internet-facing web application. In another case, a then previously unknown vulnerability (CVE-2021-44207) in USAHerds, which is a web application used by agriculture officials to manage animal disease control and prevention, livestock identification and movement. Also, APT41 reportedly started to exploit the infamous Log4j vulnerability (CVE-2021-44228) within hours of Proof-of-Concept (PoC) code becoming available. Patches for both vulnerabilities are available. Once successful in breaking into the victim's network, the threat actor performed reconnaissance and credential harvesting activities. What is APT41?APT41 is a threat actor who has been active since at least 2012. Also known as TA415, Double Dragon, Barium, GREF and WickedPanda, the group reportedly performs Chinese state-sponsored espionage activities. APT41 targets organizations in multiple countries across a wide range of industries, such as telecommunications, industrial and engineering and think tanks. In 2020, five alleged members of the group were charged by the U.S. Justice Department for hacking more than 100 companies in the United States.What are the Tools Used by APT41?APT41 is known to use the following tools:ASPXSpy - web shell backdoorBITSAdmin - PowerShell cmdlets for creating and managing file transfers.BLACKCOFFEE - backdoor that disguise its communications as benign traffic to legitimate websites certutil - command-line utility tool used for manipulating certification authority (CA) data and components.China Chopper - web shell backdoor that allows attacker to have remote access to an enterprise networkCobalt Strike - a commercial penetration testing tool, which allows users to perform a wide range of activitiesDerusbi - DLL backdoorEmpire - PowerShell post-exploitation agent, which provides a wide range of attack activities to usersgh0st RAT - Remote Access Trojan (RAT)MESSAGETAP - data mining malware Mimikatz - open-source credential dumpernjRAT - Remote Access Trojan (RAT)PlugX - Remote Access Trojan (RAT)PowerSploit - open-source, offensive security framework which allows users to perform a wide range of activitiesROCKBOOT - BootkitShadowPad - backdoorWinnti for Linux - Remote Access Trojan (RAT) for LinuxZxShell - Remote Access Trojan (RAT)Badpotato - open-source tool that allows elevate user rights towards System rightsDustPan - shellcode loader. aka StealthVectorDEADEYE - downloaderLOWKEY - backdoorKeyplug - backdoorWhat are Other Vulnerabilities Known to be Exploited by APT41?APT41 exploited the following, but not restricted to, these vulnerabilities in the past:CVE-2020-10189 (ManageEngine Desktop Central remote code execution vulnerability)CVE-2019-19781 (Vulnerability in Citrix Application Delivery Controller, Citrix Gateway, and Citrix SD-WAN WANOP appliance)CVE-2019-3396 (Atlassian Confluence Widget Connector Macro Velocity Template Injection)CVE-2017-11882 (Microsoft Office Memory Corruption Vulnerability)CVE-2017-0199 (Microsoft Office/WordPad Remote Code Execut Malware Tool Vulnerability Threat Guideline APT 41 APT 15 APT 15

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.

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.

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.

These charts summarize the IOCs attached to this magazine and provide a glimpse of the threats discussed. Trending Cyber News and Threat Intelligence Russian Cyberattacks Pose Greater Risk to Governments and Other Insights from Our Annual Report (published: October 7, 2021) Approximately 58% of all nation-state attacks observed by Microsoft between July 2020 and June 2021 have been attributed to the Russian-sponsored threat groups, specifically to Cozy Bear (APT29, Nobelium) associated with the Russian Foreign Intelligence Service (SVR). The United States, Ukraine, and the UK were the top three targeted by them. Russian Advanced Persistent Threat (APT) actors increased their effectiveness from a 21% successful compromise rate to a 32% rate comparing year to year. They achieve it by starting an attack with supply-chain compromise, utilizing effective tools such as web shells, and increasing their skills with the cloud environment targeting. Russian APTs are increasingly targeting government agencies for intelligence gathering, which jumped from 3% of their targets a year ago to 53% – largely agencies involved in foreign policy, national security, or defense. Following Russia by the number of APT cyberattacks were North Korea (23%), Iran (11%), and China (8%). Analyst Comment: As the collection of intrusions for potential disruption operations via critical infrastructure attacks became too risky for Russia, it refocused back to gaining access to and harvesting intelligence. The scale and growing effectiveness of the cyberespionage requires a defence-in-depth approach and tools such as Anomali Match that provide real-time forensics capability to identify potential breaches and known actor attributions.

Trending Cyber News and Threat Intelligence S.O.V.A. – A New Android Banking Trojan with Fowl Intentions (published: September 10, 2021) ThreatFabric researchers have discovered a new Android banking trojan called S.O.V.A. The malware is still in the development and testing phase and the threat actor is publicly-advertising S.O.V.A. for trial runs targeting banks to improve its functionality. The trojan’s primary objective is to steal personally identifiable information (PII). This is conducted through overlay attacks, keylogging, man-in-the-middle attacks, and session cookies theft, among others. The malware author is also working on other features such as distributed denial-of-service (DDoS) and ransomware on S.O.V.A.’s project roadmap. Analyst Comment: Always keep your mobile phone fully patched with the latest security updates. Only use official locations such as the Google Play Store / Apple App Store to obtain your software, and avoid downloading applications, even if they appear legitimate, from third-party stores. Furthermore, always review the permissions an app will request upon installation.

Trending Cyber News and Threat Intelligence UK and Allies Accuse China for a Pervasive Pattern of Hacking, Breaching Microsoft Exchange Servers (published: July 19, 2021) On July 19th, 2021, the US, the UK, and other global allies jointly accused China in a pattern of aggressive malicious cyber activity. First, they confirmed that Chinese state-backed actors (previously identified under the group name Hafnium) were responsible for gaining access to computer networks around the world via Microsoft Exchange servers. The attacks took place in early 2021, affecting over a quarter of a million servers worldwide. Additionally, APT31 (Judgement Panda) and APT40 (Kryptonite Panda) were attributed to Chinese Ministry of State Security (MSS), The US Department of Justice (DoJ) has indicted four APT40 members, and the Cybersecurity and Infrastructure Security Agency (CISA) shared indicators of compromise of the historic APT40 activity. Analyst Comment: Network defense-in-depth and adherence to information security best practices can assist organizations in reducing the risk. Pay special attention to the patch and vulnerability management, protecting credentials, and continuing network hygiene and monitoring. When possible, enforce the principle of least privilege, use segmentation and strict access control measures for critical data. Organisations can use Anomali Match to perform real time forensic analysis for tracking such attacks.

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
