(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.

Abraham's Ax Likely Linked to Moses Staff
(published: January 26, 2023)
Cobalt Sapling is an Iran-based threat actor active in hacking, leaking, and sabotage since at least November 2020. Since October 2021, Cobalt Sapling has been operating under a persona called Moses Staff to leak data from Israeli businesses and government entities. In November 2022, an additional fake identity was created, Abraham's Ax, to target government ministries in Saudi Arabia. Cobalt Sapling uses their custom PyDCrypt loader, the StrifeWater remote access trojan, and the DCSrv wiper styled as ransomware.
Analyst Comment: A defense-in-depth approach can assist in creating a proactive stance against threat actors attempting to destroy data. Critical systems should be segregated from each other to minimize potential damage, with an |

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 2020-2022, Iran-sponsored MuddyWater (Static Kitten, Mercury) group went through abusing several legitimate remote administration tools: RemoteUtilities, followed by ScreenConnect and then Atera Agent. Since September 2022, a new campaign attributed to MuddyWater uses spearphishing to deliver links to archived MSI files with yet another remote administration tool: Syncro. Deep Instinct researchers observed the targeting of Armenia, Azerbaijan, Egypt, Iraq, Israel, Jordan, Oman, Qatar, Tajikistan, and United Arab Emirates.
Analyst Comment: Network defenders are advised to establish a baseline for typical running processes and monitor for remote desktop solutions that are not common in the organization.

Babuk Ransomware Variant in Major New Attack
(published: December 7, 2022)
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.

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).
Analyst Comment: Website owners should keep their systems updated, use unique strong passwords and introduce MFA for all privileged or internet facing resources, and employ server-side scanning to detect unauthorized malicious content. Implement secure storage for website backups.

Leaked Android Platform Certificates Create Risks for Users
(published: December 2, 2022)
On November 30, 2022, Google reported 10 different Android platform certificates that were seen actively abused in the wild to sign malware. Rapid7 researchers found that the reported signed samples are adware, so it is possible that these platform certificates may have been widely available. It is not shared how these platform certificates could have been leaked.
Analyst Comment: Malware signed with a platform certificate can enjoy privileged execution with system permissions, including permissions to access user data. Developers should minimize the number of applications requiring a platform certificate signature.

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. Links from alternative incoming messaging such as from contact forms should be treated as thorough as links from incoming email traffic.

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). Restrict the use of RDP, SSH, Telnet, virtual desktop and similar services in your environment.

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. Organizations should include callback phishing attacks awareness into their anti-phishing training.

ZINC Weaponizing Open-Source Software
(published: September 29, 2022)
Microsoft researchers described recent developments in Lazarus Group (ZINC) campaigns that start from social engineering conversations on LinkedIn. Since June 2022, Lazarus was able to trojanize several open-source tools (KiTTY, muPDF/Subliminal Recording software installer, PuTTY, TightVNC, and Sumatra PDF Reader). When a target extracts the trojanized tool from the ISO file and installs it, Lazarus is able to deliver their custom malware such as EventHorizon and ZetaNile. In many cases, the final payload was not delivered unless the target manually established an SSH connection to an attacker-controlled IP address provided in the attached ReadMe.txt file.
Analyst Comment: All known indicators connected to this recent Lazarus Group campaign are available in the Anomali platform and customers are advised to block these on their infrastructure. Researchers should monitor for the additional User Execution step required for payload delivery. Defense contractors should be aware of advanced social engineering efforts abusing LinkedIn and other means of establishing trusted communication.

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.

BRONZE PRESIDENT Targets Government Officials
(published: September 8, 2022)
Secureworks researchers detected a new campaign by China-sponsored group Mustang Panda (Bronze President). In June and July 2022, the group used spearphishing to deliver the PlugX malware to government officials in Europe, the Middle East, and South America. To bypass mail-scanning antiviruses, the archived email attachment had malware embedded eight levels deep in a sequence of hidden folders named with special characters.
Analyst Comment: Many advanced attacks start with basic techniques such as unwarranted email with malicious attachment that requires the user to open it and enable macros. It is important to teach your users basic online hygiene and phishing awareness.

2022-09-08 14:14:00 | North Korean state-sponsored hacker group Lazarus adds new RAT to its malware toolset (lien direct) | Security researchers have discovered a new remote access Trojan (RAT) being used in attack campaigns this year by Lazarus, a threat actor tied to the North Korean government. The new RAT has been used alongside other malware implants attributed to Lazarus and it's mainly used in the first stages of an attack.Dubbed MagicRAT, the new Lazarus malware program was developed using Qt, a framework commonly used to develop graphical user interfaces for cross-platform applications. Since the Trojan doesn't have a GUI, researchers from Cisco Talos believe the reason for using Qt was to make detection harder.To read this article in full, please click here | Malware Threat | APT 38 | |

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 |
