Overview

The ransomware group known as Cl0p is a variant of the previously tracked CryptoMix strain. Early Cl0p activity was linked to financially motivated operations attributed to TA505, including phishing campaigns observed in 2019.

Those campaigns commonly relied on macro-enabled documents that deployed the Get2 loader. Once initial access was established, operators moved into reconnaissance, lateral movement, and data exfiltration before deploying ransomware across the victim environment.

After execution, Cl0p variants have been observed appending extensions such as .clop, .CIIp, .Cllp, and .C_L_O_P. Associated ransom notes have included filenames like ClopReadMe.txt, README_README.txt, Cl0pReadMe.txt, and READ_ME_!!!.TXT.

The operation later shifted from phishing-led delivery to intrusion campaigns centered on exploiting vulnerabilities in internet-facing enterprise software and managed file transfer products.
