(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
Google Threat Intelligence Group (GTIG) has observed increasing efforts from several Russia state-aligned threat actors to compromise Signal Messenger accounts used by individuals of interest to Russia's intelligence services. While this emerging operational interest has likely been sparked by wartime demands to gain access to sensitive government and military communications in the context of Russia's re-invasion of Ukraine, we anticipate the tactics and methods used to target Signal will grow in prevalence in the near-term and proliferate to additional threat actors and regions outside the Ukrainian theater of war.
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.

Researchers can disclose two brand-new vulnerabilities in OpenSSH now that patches have been released.
Qualys discovered the bugs in January, per its disclosure timeline. These vulnerabilities allow miscreants to perform machine-in-the-middle (MitM) attacks on the OpenSSH client and pre-authentication denial-of-service (DoS) attacks.
Patches for CVE-2025-26465 and CVE-2025-26466 were released this morning. Although their respective severity scores (6.8 and 5.9 out of 10) don't necessarily scream "patch me right away" – it certainly doesn't seem as bad as last year's regreSSHion issue – they're both likely to raise some degree of concern given the tool's prominence.
First observed in March 2024, “BlackLock” (aka El Dorado or Eldorado) has rapidly emerged as a major player in the ransomware-as-a-service (RaaS) ecosystem. By Q4 2024, it ranked as the 7th most prolific ransomware group on data-leak sites, fueled by a staggering 1,425% increase in activity from Q3. BlackLock uses a double extortion tactic—encrypting data while stealing sensitive information—to pressure victims with the threat of public exposure. Its ransomware is built to target Windows, VMWare ESXi, and Linux environments, though the Linux variant offers fewer features than its Windows counterpart.
