  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 ★★

Hackers Using Fake YouTube Apps To Infect Android Devices

Le groupe de piratage APT36, également connu sous le nom de \\ 'Tribe Transparent, a été découvert à l'aide d'applications Android malveillantes qui imitent YouTube pour infecter leurs cibles \' avec le Troie (rat) d'accès à distance mobile appelé \\ appelé \'Caprarat \'. Pour les personnes inconscientes, l'APT36 (ou la tribu transparente) est un groupe de piratage présumé lié au Pakistan principalement connu pour avoir utilisé des applications Android malveillantes pour attaquer la défense indienne et les agences gouvernementales, les organisations impliquées dans la région du Cachemire, ainsi que les militants des droits de l'homme travaillant travailsur des questions liées au Pakistan. Sentinelabs, une entreprise de cybersécurité, a pu identifier trois packages d'applications Android (APK) liés à la Caprarat de la tribu transparente, qui a imité l'apparence de YouTube. & # 8220; Caprarat est un outil très invasif qui donne à l'attaquant un contrôle sur une grande partie des données sur les appareils Android qu'il infecte, & # 8221;Le chercheur de sécurité Sentinellabs Alex Delamotte a écrit dans une analyse lundi. Selon les chercheurs, les APK malveillants ne sont pas distribués via Google Play Store d'Android, ce qui signifie que les victimes sont probablement socialement conçues pour télécharger et installer l'application à partir d'une source tierce. L'analyse des trois APK a révélé qu'elles contenaient le Caprarat Trojan et ont été téléchargées sur Virustotal en avril, juillet et août 2023. Deux des Caprarat APK ont été nommés \\ 'YouTube \', et l'un a été nommé \'Piya Sharma \', associée à un canal potentiellement utilisé pour les techniques d'ingénierie sociale basées sur la romance pour convaincre les cibles d'installer les applications. La liste des applications est la suivante: base.media.service moves.media.tubes videos.watchs.share Pendant l'installation, les applications demandent un certain nombre d'autorisations à risque, dont certaines pourraient initialement sembler inoffensives pour la victime pour une application de streaming médiatique comme YouTube et la traiter sans soupçon. L'interface des applications malveillantes tente d'imiter l'application YouTube réelle de Google, mais ressemble plus à un navigateur Web qu'à une application en raison de l'utilisation de WebView à partir de l'application Trojanisée pour charger le service.Ils manquaient également de certaines fonctionnalités et fonctions disponibles dans l'application Android YouTube native légitime. Une fois que Caprarat est installé sur le dispositif de victime, il peut effectuer diverses actions telles que l'enregistrement avec le microphone, les caméras avant et arrière, la collecte de SMS et les contenus de messages multimédias et les journaux d'appels, d'envoi de messages SMS, de blocage des SMS entrants, initier les appels téléphoniques, prendre des captures d'écran, des paramètres système primordiaux tels que GPS & AMP;Réseau et modification des fichiers sur le système de fichiers du téléphone \\ Selon Sentinelabs, les variantes de caprarat récentes trouvées au cours de la campagne actuelle indiquent un développement continu des logiciels malveillants par la tribu transparente. En ce qui concerne l'attribution, les adresses IP des serveurs de commande et de contrôle (C2) avec lesquels Caprarat communique sont codées en dur dans le fichier de configuration de l'application et ont été liés aux activités passées du groupe de piratage. Cependant, certaines adresses IP étaient liées à d'autres campagnes de rats, bien que la relation exacte entre ces acteurs de menace et la tribu transparente reste claire.

Trending Cyber News and Threat Intelligence First-Ever Attack Leveraging Kubernetes RBAC to Backdoor Clusters (published: April 21, 2023) A new Monero cryptocurrency-mining campaign is the first recorded case of gaining persistence via Kubernetes (K8s) Role-Based Access Control (RBAC), according to Aquasec researchers. 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. A defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) approach is a good mitigation step to help prevent actors from highly-active threat groups.

Trending Cyber News and Threat Intelligence WinorDLL64: A Backdoor From The Vast Lazarus Arsenal? (published: February 23, 2023) When the Wslink downloader (WinorLoaderDLL64.dll) was first discovered in 2021, it had no known payload and no known attribution. Now ESET researchers have discovered a Wslink payload dubbed WinorDLL64. This backdoor uses some of Wslink functions and the Wslink-established TCP connection encrypted with 256-bit AES-CBC cipher. WinorDLL64 has some code similarities with the GhostSecret malware used by North Korea-sponsored Lazarus Group. Analyst Comment: Wslink and WinorDLL64 use a well-developed cryptographic protocol to protect the exchanged data. Innovating advanced persistent groups like Lazarus often come out with new versions of their custom malware.

(lien direct) CyberheistNews Vol 13 #09 CyberheistNews Vol 13 #09  |   February 28th, 2023 [Eye Opener] Should You Click on Unsubscribe? By Roger A. Grimes. Some common questions we get are "Should I click on an unwanted email's 'Unsubscribe' link? Will that lead to more or less unwanted email?" The short answer is that, in general, it is OK to click on a legitimate vendor's unsubscribe link. But if you think the email is sketchy or coming from a source you would not want to validate your email address as valid and active, or are unsure, do not take the chance, skip the unsubscribe action. In many countries, legitimate vendors are bound by law to offer (free) unsubscribe functionality and abide by a user's preferences. For example, in the U.S., the 2003 CAN-SPAM Act states that businesses must offer clear instructions on how the recipient can remove themselves from the involved mailing list and that request must be honored within 10 days. Note: Many countries have laws similar to the CAN-SPAM Act, although with privacy protection ranging the privacy spectrum from very little to a lot more protection. The unsubscribe feature does not have to be a URL link, but it does have to be an "internet-based way." The most popular alternative method besides a URL link is an email address to use. In some cases, there are specific instructions you have to follow, such as put "Unsubscribe" in the subject of the email. Other times you are expected to craft your own message. Luckily, most of the time simply sending any email to the listed unsubscribe email address is enough to remove your email address from the mailing list.

Trending Cyber News and Threat Intelligence No Pineapple! –DPRK Targeting of Medical Research and Technology Sector (published: February 2, 2023) In August-November 2022, North Korea-sponsored group Lazarus has been engaging in cyberespionage operations targeting defense, engineering, healthcare, manufacturing, and research organizations. The group has shifted their infrastructure from using domains to be solely IP-based. For initial compromise the group exploited known vulnerabilities in unpatched Zimbra mail servers (CVE-2022-27925 and CVE-2022-37042). Lazarus used off the shelf malware (Cobalt Strike, JspFileBrowser, JspSpy webshell, and WSO webshell), abused legitimate Windows and Unix tools (such as Putty SCP), and tools for proxying (3Proxy, Plink, and Stunnel). Two custom malware unique to North Korea-based advanced persistent threat actors were a new Grease version that enables RDP access on the host, and the Dtrack infostealer. Analyst Comment: Organizations should keep their mail server and other publicly-facing systems always up-to-date with the latest security features. Lazarus Group cyberespionage attacks are often accompanied by stages of multi-gigabyte exfiltration traffic. Suspicious connections and events should be monitored, detected and acted upon.

The variant is used by a technically-skilled group, possibly by the Black Basta ransomware. The actors use special shortcuts, folder icons and settings to make folders impersonating disks and a recycle bin directory. They also name certain folders with the 00A0 (no-break space) Unicode character thus hindering Windows Explorer and the command shell from displaying the folder and all the files inside it. Analyst Comment: Several behavior detections could be used to spot similar PlugX malware variants: DLL side loading, adding registry persistence, and payload execution with rundll32.exe.

The malicious torchtriton dependency on PyPI uses the dependency confusion attack by having the same name as the legitimate one on the PyTorch repository (PyPI takes precedence unless excluded). The actor behind the malicious library claims that it was part of ethical research and that he alerted some affected companies via HackerOne programs (Facebook was allegedly alerted). At the same time the library’s features are more aligned with being a malware than a research project. The code is obfuscated, it employs anti-VM techniques and doesn’t stop at fingerprinting. It exfiltrates passwords, certain files, and the history of Terminal commands. Stolen data is sent to the C2 domain via encrypted DNS queries using the wheezy[.]io DNS server. Analyst Comment: The presence of the malicious torchtriton binary can be detected, and it should be uninstalled. PyTorch team has renamed the 'torchtriton' library to 'pytorch-triton' and reserved the name on PyPI to prevent similar attacks.

Watchguard.webp 2022-12-22 00:00:00 Le rapport Threat Lab de WatchGuard révèle que la principale menace emprunte exclusivement des connexions chiffrées (lien direct) Paris, le 4 janvier 2023 – WatchGuard® Technologies, leader mondial de la cybersécurité unifiée, publie son dernier Rapport trimestriel sur la sécurité Internet, qui présente les grandes tendances en matière de malwares et de menaces pour la sécurité des réseaux et des endpoints analysées par les chercheurs du Threat Lab de WatchGuard au 3ème trimestre 2022. Ses conclusions clés révèlent notamment que la principale menace du trimestre en matière de logiciels malveillants a été détectée exclusivement via des connexions chiffrées, que les attaques ICS conservent leur popularité, que le logiciel malveillant LemonDuck évolue au-delà du cryptominage, et qu'un moteur de triche Minecraft diffuse une charge utile malveillante. " Nous ne saurions trop insister sur l'importance d'activer l'inspection HTTPS, même si elle nécessite quelques réglages et exceptions pour fonctionner correctement. La majorité des logiciels malveillants utilisent le protocole chiffré HTTPS, et ces menaces ne sont pas détectées en l'absence d'inspection ", a déclaré Corey Nachreiner, Chief Security Officer chez WatchGuard Technologies. " À juste titre, les plus grands objets de convoitise des cybercriminels, comme les serveurs Exchange ou les systèmes de gestion SCADA, méritent également un maximum d'attention. Lorsqu'un correctif est disponible, il est important de procéder immédiatement à la mise à jour, car les cybercriminels finiront par tirer profit de toute organisation qui n'a pas encore mis en œuvre le dernier correctif. " Le rapport sur la sécurité Internet du 3ème trimestre contient d'autres résultats clés, notamment : La grande majorité des logiciels malveillants empruntent des connexions chiffrées – Bien qu'il soit arrivé 3ème dans la liste classique des 10 principaux malwares du 3ème trimestre, Agent.IIQ a pris la tête de la liste des logiciels malveillants chiffrés pour cette même période. De fait, en regardant les détections de ce malware sur ces deux listes, il apparaît que toutes les détections d'Agent.IIQ proviennent de connexions chiffrées. Au 3ème trimestre, si une appliance Firebox inspectait le trafic chiffré, 82 % des logiciels malveillants détectés passaient par une connexion chiffrée, ce qui correspond à seulement 18 % de détections sans chiffrement. Si le trafic chiffré n'est pas inspecté sur Firebox, il est très probable que ce ratio moyen s'applique et que l'entreprise passe à côté d'une énorme partie des logiciels malveillants.   Les systèmes ICS et SCADA restent les cibles d'attaques les plus courantes – Ce trimestre, une attaque de type injection SQL ayant touché plusieurs fournisseurs a fait son apparition dans la liste des dix principales attaques réseau. Advantech fait partie des entreprises concernées. Son portail WebAccess est utilisé pour les systèmes SCADA dans une variété d'infrastructures critiques. Un autre exploit sérieux au 3ème trimestre, également classé parmi les cinq principales attaques réseau en termes de volume, a visé les versions 1.2.1 et antérieures du logiciel U.motion Builder de Schneider Electric. Un rappel brutal du fait que les cybercriminels ne se contentent pas d'attendre tranquillement la prochaine opportunité, mais qu'ils cherchent activement à compromettre les systèmes chaque fois que cela est possible.   Les vulnérabilités des serveurs Exchange continuent de poser des risques – La C Ransomware Malware Tool Threat APT 3 ★★★

One modification is lowering detection by abusing the legitimate Microsoft signed process: DLL side-loading into NTSD.exe — a Symbolic Debugger tool for Windows. The mechanism to remove the available Shadow Copies was changed to using Component Object Model objects that execute Windows Management Instrumentation queries. This sample was detected in a large, unnamed manufacturing company where attackers had network access and were gathering information for two weeks. They have compromised the company’s domain controller and used it to distribute ransomware to all devices within the organization through Group Policy Object. The delivered BAT script bypasses User Account Control and executes a malicious MSI file that contains files for DLL side-loading and an open-source-based reflective loader (OCS files). Analyst Comment: The attackers strive to improve their evasion techniques, their malware on certain steps hides behind Microsoft-signed processes and exists primarily in device memory.

Trending Cyber News and Threat Intelligence Chinese Gambling Spam Targets World Cup Keywords (published: December 2, 2022) Since 2018, a large-scale website infection campaign was affecting up to over 100,000 sites at a given moment. Infected websites, mostly oriented at audiences in China, were modified with additional scripts. Compromised websites were made to redirect users to Chinese gambling sites. Title and Meta tags on the compromised websites were changed to display keywords that the attackers had chosen to abuse search engine optimization (SEO). At the same time, additional scripts were switching the page titles back to the original if the visitor fingerprinting did not show a Chinese search engine from a preset list (such as Baidu).

Trending Cyber News and Threat Intelligence DEV-0569 Finds New Ways to Deliver Royal Ransomware, Various Payloads (published: November 17, 2022) From August to October, 2022, Microsoft researchers detected new campaigns by a threat group dubbed DEV-0569. For delivery, the group alternated between delivering malicious links by abusing Google Ads for malvertising and by using contact forms on targeted organizations’ public websites. Fake installer files were hosted on typosquatted domains or legitimate repositories (GitHub, OneDrive). First stage was user-downloaded, signed MSI or VHD file (BatLoader malware), leading to second stage payloads such as BumbleBee, Gozi, Royal Ransomware, or Vidar Stealer. Analyst Comment: DEV-0569 is a dangerous group for its abuse of legitimate services and legitimate certificates. Organizations should consider educating and limiting their users regarding software installation options.

Trending Cyber News and Threat Intelligence Alert (AA22-294A) #StopRansomware: Daixin Team (published: October 21, 2022) Daixin Team is a double-extortion ransomware group that has been targeting US businesses, predominantly in the healthcare sector. Since June 2022, Daixin Team has been encrypting electronic health record services, diagnostics services, imaging services, and intranet services. The group has exfiltrated personal identifiable information and patient health information. Typical intrusion starts with initial access through virtual private network (VPN) servers gained by exploitation or valid credentials derived from prior phishing. They use SSH and RDP for lateral movement and target VMware ESXi systems with ransomware based on leaked Babuk Locker source code. Analyst Comment: Network defenders should keep organization’s VPN servers up-to-date on security updates. Enable multifactor authentication (MFA) on your VPN server and other critical accounts (administrative, backup-related, and webmail).

This is a prime example of why it's important to always keep third-party PC manufacturer software, which is often neglected, up to date, as well as to add vulnerable versions to blocklists.“The most notable tool delivered by the attackers was a user-mode module that gained the ability to read and write kernel memory due to the CVE-2021-21551 vulnerability in a legitimate Dell driver,” security researchers from antivirus firm ESET said in a recent report. “This is the first ever recorded abuse of this vulnerability in the wild. The attackers then used their kernel memory write access to disable seven mechanisms the Windows operating system offers to monitor its actions, like registry, file system, process creation, event tracing etc., basically blinding security solutions in a very generic and robust way.”To read this article in full, please click here Tool Vulnerability APT 38

Trending Cyber News and Threat Intelligence New Royal Ransomware Emerges in Multi-Million Dollar Attacks (published: September 29, 2022) AdvIntel and BleepingComputer researchers describe the Royal ransomware group. Several experienced ransomware actors formed this group in January 2022. It started with third-party encryptors such as BlackCat, switched to using its own custom Zeon ransomware, and, since the middle of September 2022, the Royal ransomware. Royal group utilizes targeted callback phishing attacks. Its phishing emails impersonating food delivery and software providers contained phone numbers to cancel the alleged subscription (after the alleged end of a free trial). If an employee calls the number, Royal uses social engineering to convince the victim to install a remote access tool, which is used to gain initial access to the corporate network. Analyst Comment: Use services such as Anomali's Premium Digital Risk Protection to detect the abuse of your brands in typosquatting and phishing attacks.

Trending Cyber News and Threat Intelligence Microsoft Investigates Iranian Attacks Against the Albanian Government (published: September 8, 2022) Microsoft researchers discovered that groups working under Iran’s Ministry of Intelligence and Security (MOIS, tracked as OilRig) attacked the government of Albania. The attackers started with initial intrusion in May 2021, proceeded with mailbox exfiltrations between October 2021 and January 2022, organized controlled leaks, and culminated on July 15, 2022, with disruptive ransomware and wiper attacks. This attack is probably a response to the June 2021 Predatory Sparrow’s anti-Iranian cyber operations promoting the Mujahedin-e Khalq (MEK), an Iranian dissident group largely based in Albania. Analyst Comment: MOIS attack on Albania uses messaging and targeting similar to the previous MEK-associated attack on Iran. It tells us that Iran has chosen to engage in a form of direct and proportional retaliation as it sees it. Still, the attack and its attribution caused Albania to cut diplomatic ties with Iran and expel the country's embassy staff. Organizations should implement multifactor authentication (MFA) for mailbox access and remote connectivity. Anomali platform users advised to block known OilRig network indicators.

2022-09-08 08:39:42 Lazarus and the tale of three RATs (lien direct) By Jung soo An, Asheer Malhotra and Vitor Ventura.Cisco Talos has been tracking a new campaign operated by the Lazarus APT group, attributed to North Korea by the United States government. This campaign involved the exploitation of vulnerabilities in VMWare Horizon to gain an initial foothold into targeted organizations.Targeted organizations include energy providers from around the world, including those headquartered in the United States, Canada and Japan. The campaign is meant to infiltrate organizations around the world for establishing long term access and subsequently exfiltrating data of interest to the adversary's nation-state.Talos has discovered the use of two known families of malware in these intrusions - VSingle and YamaBot.Talos has also discovered the use of a recently disclosed implant we're calling "MagicRAT" in this campaign. IntroductionCisco Talos observed North Korean state-sponsored APT Lazarus Group conducting malicious activity between February and July 2022. Lazarus has been previously attributed to the North Korean government by the U.S. Cybersecurity and Infrastructure Security Agency (CISA). The entry vectors involve the successful exploitation of vulnerabilities in VMWare products to establish initial footholds into enterprise networks, followed by the deployment of the group's custom malware implants, VSingle and YamaBot. In addition to these known malware families, we have also discovered the use of a previously unknown malware implant we're calling "MagicRAT."This campaign was previously partially disclosed by other security firms, but our findings reveal more details about the adversary's modus operandi. We have also observed an overlap of command and control (C2) and payload-hosting infrastructure between our findings and the U.S. Cybersecurity and Infrastructure Security Agency's (CISA) June advisory that detailed continued attempts from threat actors to compromise vulnerable VMWare Horizon servers.In this research, we illustrate Lazarus Group's post-exploitation tactics, techniques and procedures (TTPs) to establish a foothold, perform initial reconnaissance, deploy bespoke malware and move laterally across infected enterprises. We also provide details about the activities performed by the attackers when the VSingle backdoor is instrumented on the infected endpoints.In this campaign, Lazarus was primarily targeting energy companies in Canada, the U.S. and Japan. The main goal of these attacks was likely to establish long-term access into victim networks to conduct espionage operations in support of North Korean govern Malware Tool Vulnerability Threat Medical APT 38

Trending Cyber News and Threat Intelligence 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.

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.

Morphisec Labs researchers discovered a new Windows framework used by the group in its campaign targeting Pakistani government and defense departments. The attack starts with a spearphishing RTF attachment. If opened in a Microsoft Office application, it downloads a malicious remote template. After the victim enables editing (macroses) a multi-stage framework deployment starts. It includes two shellcode stages followed by main DLL that, based on victim fingerprinting, downloads a custom set of additional information-stealing modules. Analyst Comment: The described DoNot Team framework is pretty unique in its customisation, fingerprinting, and module implementation. At the same time, the general theme of spearphishing attachment that asks the targeted user to enable editing is not new and can be mitigated by anti-phishing training and Microsoft Office settings hardening.

Trending Cyber News and Threat Intelligence 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).

Trending Cyber News and Threat Intelligence Update: The Phish Goes On - 5 Million Stolen Credentials and Counting (published: June 16, 2022) PIXM researchers describe an ongoing, large-scale Facebook phishing campaign. Its primary targets are Facebook Messenger mobile users and an estimated five million users lost their login credentials. The campaign evades Facebook anti-phishing protection by redirecting to a new page at a legitimate service such as amaze.co, famous.co, funnel-preview.com, or glitch.me. In June 2022, the campaign also employed the tactic of displaying legitimate shopping cart content at the final page for about two seconds before displaying the phishing content. The campaign is attributed to Colombian actor BenderCrack (Hackerasueldo) who monetizes displaying affiliate ads. Analyst Comment: Users should check what domain is asking for login credentials before providing those.

Trending Cyber News and Threat Intelligence COBALT MIRAGE Conducts Ransomware Operations in U.S. (published: May 12, 2022) Secureworks researchers describe campaigns by Iran-sponsored group Cobalt Mirage. These actors are likely part of a larger group, Charming Kitten (Phosphorus, APT35, Cobalt Illusion). In 2022, Cobalt Mirage deployed BitLocker ransomware on a US charity systems, and exfiltrated data from a US local government network. Their ransomware operations appear to be a low-scale, hands-on approach with rare tactics such as sending a ransom note to a local printer. The group utilized its own custom binaries including a Fast Reverse Proxy client (FRPC) written in Go. It also relied on mass scanning for known vulnerabilities (ProxyShell, Log4Shell) and using commodity tools for encryption, internal scanning, and lateral movement. Analyst Comment: However small your government or NGO organization is, it still needs protection from advanced cyber actors. Keep your system updated, and employ mitigation strategies when updates for critical vulnerabilities are not available.

Trending Cyber News and Threat Intelligence 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.

Trending Cyber News and Threat Intelligence 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.

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 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 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.
