Summary
Clop ransomware is a variant of a previously known strain called CryptoMix. In 2019, Clop was delivered as the final payload of a phishing campaign associated with the financially motivated actor TA505. In 2020, Clop has evolved from a ransomware delivered through malicious spam to one being used in targeted campaigns against high-profile companies. Clop appends the .clop extension to the victim’s files. We have observed different variants using different extensions, such as .CIIp, .Cllp and .C_L_O_P. This ransomware includes various features to avoid detection. Observed Clop samples try to kill several processes and services related to backups and security solutions.
