Projectzorgo ransomware actively spreading in the wild

May 4, 2020

The SonicWall Capture Labs Threat Research Team observed reports of a new variant family of PROJECTZORGO ransomware [PROJECTZORGO.RSM] actively spreading in the wild.

The PROJECTZORGO ransomware has been specially designed by a team of underground hackers for bad intentions. The ransomware encrypts the victim’s files with a strong encryption algorithm until the victim pays a fee to get them back.

This cyber-criminal group has been active since November 2019 based on their Twitter account.

Infection Cycle:

The ransomware adds the following files to the system:

  • Malware.exe
    • % App.path%\ TXT
      • Instruction for recovery
    • %App.path%\ [Name]. <Projectzorgo>

Once the computer is compromised, the ransomware runs the following commands:

The ransomware encrypts all the files and appends the [Projectzorgo]  extension onto each encrypted file’s filename. It is capable of targeting various file formats such as .exe, .jpeg, .docx,.mp3, .pdf, .html, and others that can make those files useless.

After encrypting all personal documents, the ransomware shows the following text file containing a message reporting that the computer has been encrypted and to contact its developer for unlock instructions.

We have been monitoring varying hits over the past few days for the signature that blocks this threat:
