Egregor is a malicious software variant of the Sekhmet ransomware that operates on a Ransomware-as-a-Service (RaaS) model. It is speculated to be associated with former Maze affiliates, and is notorious for its double extortion tactics, which involve not only encrypting the victim's data but also publicly shaming them by leaking sensitive information. Egregor has been implicated in numerous high-profile attacks, including breaches at Ubisoft and Crytek in 2020, where it was deployed to steal and leak game source code. The Egregor ransomware gained access to systems through various methods, often leveraging other malware like Qakbot as an initial infection vector. This Trojan has been used by multiple ransomware groups, including Conti, ProLock, REvil, RansomExx, MegaCortex, and most recently, Black Basta. In a 2020 intrusion, threat actors deployed Egregor several months after GOLD MELODY obtained access to the environment. Tools like MegaSync and Rclone have also been observed in use in Egregor incidents, aiding in the ransomware's operations. Despite its widespread activity, efforts to combat Egregor have seen some success. A number of Egregor affiliates were arrested in February 2021, causing disruption to the group's operations. Furthermore, decryption tools for Egregor, along with other ransomwares like Maze and Sekhmet, have been developed and are available online, offering victims a potential means of recovering their encrypted data without paying the ransom. However, the ongoing prevalence of Egregor underscores the importance of robust cybersecurity measures to prevent initial access and infection.
