FortiGuard Labs is aware that a new ransomware “Onyx” is in the wild. The ransomware was first discovered in late April, 2022. The malware appears to be based on Chaos ransomware and overwrites files bigger than 2MB, making file recovery very difficult. What is this Significant?This is significant because the threat actor opted to have Onyx ransomware overwrite files bigger than 2MB on the compromised machine rather than encrypting them. Although the threat actor promises to decrypt the affected files after ransom payment is made, recovery of the overwritten files will be difficult.What does Onyx Ransomware do?The ransomware overwrites files bigger than 2MB on the compromised machine, encrypts files smaller than 2MB, and adds file extension “.ampkcz” to them. It also collects sensitive information such as credentials from the affected machine. It then displays the following ransom message and demands ransom from the victim in order to recover the affected files:”All of your files are currently encrypted by ONYX strain.As you already know, all of your data has been encrypted by our software.It cannot be recovered by any means without contacting our team directly.DON’T TRY TO RECOVER your data by yourselves.
