What is DotZeroCMD ransomware? And how does it implement its attack?

DotZeroCMD ransomware is ransomware “wanna-be” that pretends to be a file-encrypting threat when it’s actually not capable of locking the victims’ files up. Security experts spotted this ransomware in the late April 2018 and seem to target Windows x64-based operating systems. This fake ransomware also works as RaaS (Ransomware as Service).
Once DotZeroCMD ransomware infiltrates a targeted system, it makes changes in the Windows system files and runs a malicious program named “DotZeroCMD.Ransom-v1.2” used to simulate the file-encrypting process which does not really work. This ransomware “wanna-be” supposedly targets files with extensions like .pdf, .avi, .jpg, .doc, .txt, .mov, .html, and many more. In its effort to look like a typical ransomware threat, DotZeroCMD ransomware spawns a lock-screen instance that’s designed similarly to the infamous Petya ransomware. Its lock-screen instance contains the following message:
“Dot Zero CMD.Ransom – v1.2
