Summary
Talos recently published research regarding a new variant of destructive ransomware, which we dubbed Ranscam. During further analysis of Ranscam samples, we discovered several indicators of compromise (IOCs) that piqued our curiosity as to which malware this threat actor might be involved in or responsible for besides Ranscam. We began to expand the scope of our research into other destructive “ranscamware” in an effort to determine if they had any shared characteristics that might indicate the same threat actor or group might be responsible for multiple variants. We found several interesting ties between known destructive ransomware variants such as Jigsaw and AnonPop which correlated with the threat actor we believe to be responsible for Ranscam.
