Meet Egregor, a New Ransomware Family to Watch

Egregors operators promise to decrypt victims files and provide security recommendations in exchange for ransom payment.

Researchers have been analyzing a new ransomware family that calls itself Egregor. Attackers behind the malware, which has affected at least 13 companies, typically operate by breaking into organizations, stealing sensitive data, and running the malware to encrypt their files.
Appgate researchers tracking the threat say it contains anti-analysis techniques such as code obfuscation and packed payloads. In one of its execution stages, they found, the payload can only be decrypted if the proper key is entered in the processs command line. This means the file cant be analyzed unless someone enters the same command line used to run the payload.
Egregors ransom note promises that if the ransom is not paid within three days, the attackers will leak part of the stolen data and alert the victim companys partners and clients via mass media so they know of the breach.
If ransom is paid, Egregors operators claim they will decrypt the files and provide recommendations for securing the companys network to avoid future attacks, acting as some sort of black hat pentest team, the researchers write.
