To that finish, they put in totally different tools, similar to Course of Hacker and AdvancedIP Scanner. “Finally, after lowering system security, the adversary ran Ymir to realize their objectives,” the researchers conclude.
Ymir is the title of each the encryptor and the menace actor behind it, and can be a comparatively new entrant within the ransomware house. The malware is sort of distinctive, too, in that it operates totally from reminiscence, making the most of totally different features similar to ‘malloc’, ‘memove’, and ‘memcmp’ to stop being detected.

In that case, it could mark a wholly totally different method to ransomware assaults, and probably a notable shift in how ransomware assaults are performed.
“If the brokers are certainly the identical actors who deployed the ransomware, this might sign a brand new pattern, creating extra hijacking choices with out counting on conventional Ransomware-as-a-Service (RaaS) teams,” Kaspersky researcher Cristian Souza stated.
In any case, it’s attainable that Ymir will develop right into a formidable menace actor, infecting extra corporations within the months to return.
