What is Omerta ransomware? And how does it execute its attack?

Omerta ransomware is yet another variant of Scarab ransomware. It seems that these variants of Scarab ransomware keep coming and there seems to be no end to it. This new strain uses the .omerta extension in marking the files it encrypts. Like other Scarab variants, nothing much has changed with this new one except for the extension used to mark the encrypted files as well as the ransom note.

Once it is able to infiltrate a computer, it will drop its malicious payload on the system folder like:

  • %AppData%
  • %Local%
  • %LocalLow%
  • %Roaming%
  • %Temp%

After it drops its malicious payload, Omerta ransomware will begin to execute its attack by adding more malicious files. These malicious files may be used to repress or launch system processes that allow the crypto-malware to stay undetected. It may also modify some registry keys and sub-keys in the Windows registry which allows it to run on every system startup. Once these changes area applied, it begins the encryption process using a strong encryption algorithm. Following file encryption, it adds an email address as well as the .omerta suffix to each one of the encrypted files. It then releases its ransom note in a file named “READ THIS IF YOU WANT TO GET YOUR FILES BACK.txt” which contains the following message:

_________________________________________________________________________________________

| *** IF YOU WANT TO GET ALL YOUR FILES BACK, PLEASE READ THIS *** |

|_________________________________________________________________________________________|
