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.

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.

Xenomorph V3: a New Variant with ATS Targeting More Than 400 Institutions
(published: March 10, 2023)
Newer versions of the Xenomorph Android banking trojan are able to target 400 applications: cryptocurrency wallets and mobile banking from around the World with the top targeted countries being Spain, Turkey, Poland, USA, and Australia (in that order). Since February 2022, several small, testing Xenomorph campaigns have been detected. Its current version Xenomorph v3 (Xenomorph.C) is available on the Malware-as-a-Service model. This trojan version was delivered using the Zombinder binding service to bind it to a legitimate currency converter. Xenomorph v3 automatically collects and exfiltrates credentials using the ATS (Automated Transfer Systems) framework. The command-and-control traffic is blended in by abusing Discord Content Delivery Network.
Analyst Comment: Fraud chain automation makes Xenomorph v3 a dangerous malware that might significantly increase its prevalence on the threat landscape. Users should keep their mobile devices updated and avail of mobile antivirus and VPN protection services. Install only applications that you actually need, use the official store and check the app description and reviews. Organizations that publish applications for their customers are invited to use Anomali's Premium Digital Risk Protection service to discover rogue, malicious apps impersonating your brand that security teams typically do not search or monitor.

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. It makes it important for network defenders to leverage the knowledge of a wider security community by adding relevant premium feeds and leveraging the controls automation via Anomali Platform integrations.

[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.

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. Use the available YARA signatures and known indicators.

Chinese PlugX Malware Hidden in Your USB Devices?
(published: January 26, 2023)
Palo Alto researchers analyzed a PlugX malware variant (KilllSomeOne) that spreads via USB devices such as floppy, thumb, or flash drives. 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. Incidents responders can check USB devices for the presence of no-break space as a folder name.

PyTorch Discloses Malicious Dependency Chain Compromise Over Holidays
(published: January 1, 2023)
Between December 25th and December 30th, 2022, users who installed PyTorch-nightly were targeted by a malicious library. 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. Opensource repositories and apps are a valuable asset for many organizations but adoption of these must be security risk assessed, appropriately mitigated and then monitored to ensure ongoing integrity.

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.

In November 2022, Morphisec researchers identified a new ransomware variant based on the Babuk source code that was leaked in 2021. 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. It increases the need for the defense-in-depth approach and robust monitoring of your organization domain.
