What is CerBerSysLock ransomware? And how does it perform its attack?

CerBerSysLock ransomware is a file-encrypting Trojan that first emerged on the 7th of December this year. According to malware analysts, this ransomware threat is based on the Xorist ransomware as both of these programs use the XOR encryption algorithm in its encryption process. Aside from CerBerSysLock ransomware, there are also other ransomware Trojans that belongs to this group of ransomware such as the Blocked2 ransomware and the Zixer2 ransomware.

CerBerSysLock ransomware communicates with a new set of Command and Control or C&C servers and there is also a slight change in its encryption algorithm which prevents security researchers from cracking its code. During the encryption, it appends the.CerBerSysLocked0009881 extension on its targeted files. It then releases a ransom note named HOW TO DECRYPT FILES.txt which states the following text:

“Problem with your Files?
