ODCODC Ransomware – How Is It Distributed

In order to be widespread, ODCODC Ransomware may use several different techniques to be spread out, but the main possibilities are:

Malicious files.
Malicious URLs.

Such may be spread in various ways, varying from malicious e-mail attachments to malicious URLs shared on various suspicious websites.

ODCODC Ransomware In Detail

Once activated on the computer, ODCODC ransomware may drop its payload files in one of the several folders:

  • %AppData%
  • %Temp%
  • %Roaming%
  • %User’s Profile Folder%
  • %Windows%
  • %Desktop%

The files may be more than one and may be of the following file formats:

→ .dll, .txt, .exe, .tmp, .vbs, .bat, .cmd

They may contain random names or names that resemble a Windows process, for example, “svchost.exe”. The .tmp files are usually dropped in the %Temp% folder.

After the malicious files have been dropped, the ODCODC ransomware may employ a powerful RSA or AES encryption to files with the following extensions:

After encrypting the files of affected users, ODCODC ransomware may delete the shadow volume copies of the infected computer, eradicating any possibility of files being recovered from backups. This can happen by executing a .vbs script with the following administrative command:

After this is done, the ransomware may create a “readthis.txt” file with the following ransom message:

ODCODC Ransomware – Conclusion, Removal, and File Restoring

The bottom line for this variant of crypto-malware is that it may be part of the Rakhni or Troldesh variants. Judging by the badly written ransom note in Russian, it has been created for Russian users, but it may not originate from Russia. Such files may be decrypted via Rakhni decryptor by Kaspersky, which we have posted along with other file restoration methods in step “3. Restore files encrypted by ODCODC” below.

However, if you want to try and restore your files, we advise you to either do it on a safe computer or follow the removal instructions below to remove the malware from your PC. They are methodologically arranged to help detect and remove ODCODC ransomware effectively.

Finally, we advise you to follow this article for further updates on ODCODC ransomware and in the meantime to try the methods from step “3” below to attempt and restore your files. They may not be 100 percent successful, but there is a possibility that you might be able to revert at least some of your files.
