Microsoft tracks this actor as Mango Sandstorm, [read more about them here](https://sip.security.microsoft.com/intel-profiles/36949e052b63fa06ee586aef3d1fec8dd2e1b567e231d88c28c16299f9b25340). ## Description According to HarfangLab, MuddyWater has been utilizing legitimate RMM software in its attacks since at least 2021, but has been monitoring this campaign using Atera Agent since October 2023. Leveraging Atera\'s free trial offers, the agents seen in this campaign have been registered using both compromised enterprise and personal email accounts. The infection chain in this campaign begins with the deployment of spearphishing emails. These emails are highly tailored to the victim organization and contain malicious attachments or links. Upon interaction, MuddyWater leverages free file sharing sites to host the RMM software, in this case Atera Agent, giving the group remote access and control over compromised systems. The group likely does not rely on the Subsequently, the group is able to execute commands, conduct reconnaissance, and move laterally across the network facilitating the deployment of additional malware payloads enabling the group to maintain persistence and exfiltrate sensitive data. ## Microsoft Analysis Microsoft Threat Intelligence has identified that this campaign is likely attributed to the actor Microsoft tracks as Mango Sandstorm, an Iranian nation-state actor with ties to Iran\'s Ministry of Intelligence and Security (MOIS). In past operations, Mango Sandstorm has primarily, but not exclusively, sought to collect information assessed to have strategic value, typically from organizations in the aviation, education, defense, energy, government, and telecommunications sectors in the Middle East and North Africa. Mango Sandstorm tends to favor spearphishing attacks. In this and prior campaigns, the group has been observed using commercial RMM tools to achieve persistence in a target environment. Mango Sandstorm has been identified attempting to deliver Atera, SimpleHelp, RPort, N-able Advanced Monitoring Agent, Splashtop, Syncro, and AnyConnect. ## Detections As tools used in these types of campaigns might have legitimate uses, they are not typically detected as malicious, and proactive hunting is recommended. ## Recommendations Microsoft recommends the following mitigations to reduce the impact of activity associated with Mango Sandstorm\'s operations. - Use the Attack Simulator in Microsoft Defender for Office 365 to organize realistic, yet safe, simulated phishing and password attack campaigns in your organization by training end users against clicking URLs in unsolicited messages and disclosing their credentials. Training should include checking for poor spelling and grammar in phishing emails or the application\'s consent screen as well as spoofed app names, logos and domain URLs appearing to originate from legitimate applications or companies. Note: Attack Simulator testing currently only supports phishing emails containing links. - Encourage users to use Microsoft Edge and other web browsers that support SmartScreen, which identifies and blocks malicious websites, including phishing sites, scam sites, and sites that contain exploits and host malware. - Harden internet-facing assets and identify and se | Malware Tool Threat Medical Commercial | ★★★ | |

L'AHNLAB Security Intelligence Center (ASEC) a identifié une tendance préoccupante où les acteurs de menace exploitent les canaux YouTube pour distribuer des infostelleurs, en particulier Vidar et Lummac2.
## Description
Plutôt que de créer de nouveaux canaux, les attaquants détournent des canaux populaires existants avec des centaines de milliers d'abonnés.Le malware est déguisé en versions fissurées de logiciels légitimes, et les attaquants utilisent des descriptions et des commentaires vidéo de YouTube \\ pour distribuer les liens malveillants.Le malware Vidar, par exemple, est déguisé en installateur de logiciel Adobe, et il communique avec son serveur de commande et de contrôle (C & C) via Telegram et Steam Community.De même, Lummac2 est distribué sous le couvert de logiciels commerciaux fissurés et est conçu pour voler des informations d'identification de compte et des fichiers de portefeuille de crypto-monnaie.
La méthode des acteurs de menace \\ 'd'infiltration de canaux YouTube bien connus avec une grande base d'abonnés soulève des préoccupations concernant la portée et l'impact potentiels du malware distribué.Le malware déguisé est souvent compressé avec une protection par mot de passe pour échapper à la détection par des solutions de sécurité.Il est crucial pour les utilisateurs de faire preuve de prudence lors du téléchargement de logiciels à partir de sources non officielles et de s'assurer que leur logiciel de sécurité est à la hauteurdate pour prévenir les infections de logiciels malveillants.

## Snapshot The AhnLab Security Intelligence Center (ASEC) has identified a concerning trend where threat actors are exploiting YouTube channels to distribute Infostealers, specifically Vidar and LummaC2. ## Description Rather than creating new channels, the attackers are hijacking existing, popular channels with hundreds of thousands of subscribers. The malware is disguised as cracked versions of legitimate software, and the attackers use YouTube\'s video descriptions and comments to distribute the malicious links. The Vidar malware, for example, is disguised as an installer for Adobe software, and it communicates with its command and control (C&C) server via Telegram and Steam Community. Similarly, LummaC2 is distributed under the guise of cracked commercial software and is designed to steal account credentials and cryptocurrency wallet files. The threat actors\' method of infiltrating well-known YouTube channels with a large subscriber base raises concerns about the potential reach and impact of the distributed malware. The disguised malware is often compressed with password protection to evade detection by security solutions. It is crucial for users to exercise caution when downloading software from unofficial sources and to ensure that their security software is up to date to prevent malware infections. ## References [https://asec.ahnlab.com/en/63980/](https://asec.ahnlab.com/en/63980/) |
