(EncryptHub) is a threat actor that has come to the forefront with highly sophisticated spear-phishing attacks since 26 June 2024. In the attacks it has carried out, it exhibits a different operational strategy by carrying out all the processes necessary to obtain initial access through personalized SMS (smishing) or by calling the person directly (vishing) and tricking the victim into installing remote monitoring and management (RMM) software. When investigating the attacks carried out by the threat actor, it is evident that their social engineering techniques and persuasion skills are highly effective.
In the first phase, the actor usually creates a phishing site that targets the organization to obtain the victim's VPN credentials. The victim is then called and asked to enter the victim's details into the phishing site for technical issues, posing as an IT team or helpdesk. If the attack targeting the victim is not a call but a direct SMS text message, a fake Microsoft Teams link is used to convince the victim. After gaining access from the victim, the team runs various stealers on the compromised machine using the PowerShell
The Lumma Stealer malware campaign is exploiting compromised educational institutions to distribute malicious LNK files disguised as PDFs, targeting industries like finance, healthcare, technology, and media. Once executed, these files initiate a stealthy multi-stage infection process, allowing cybercriminals to steal passwords, browser data, and cryptocurrency wallets. With sophisticated evasion techniques, including using Steam profiles for command-and-control operations, this malware-as-a-service (MaaS) threat highlights the urgent need for robust cybersecurity defenses. Stay vigilant against deceptive phishing tactics to protect sensitive information from cyber exploitation.

Le Cloud computing, devenu incontournable pour les secteurs public et privé, favorise la transformation numérique mais offre également de nouvelles opportunités d’attaques et problématiques de sécurité pour les organisations qui l’utilisent.
L'ANSSI observe une augmentation des attaques contre les environnements cloud. Ces campagnes d'attaques, menées à des fins lucratives, d'espionnage et de déstabilisation, affectent les fournisseurs de services cloud (Cloud Service Provider, CSP), en partie ciblés pour les accès qu’ils peuvent offrir vers leurs clients. Elles ciblent également les environnements de clients de services cloud, dont l'hybridation des systèmes d'information générée par l'usage du cloud, augmente la surface d'attaque.
