ABOUT 0MEGA RANSOMWARE

This ransomware initially appeared in the month of July, 2022 and uses Double Extortion Techniques like other Ransomware Groups. Upon infection, all the victims’ files are encrypted and appended the extension .0mega to the infected files.

It can be assumed that the group had used Spear Phishing Campaigns or Malspams to compromise their victims via MS Office, as it is a common tactic used by Ransomware Operators along with RDP Disclosures to target their victims.

Currently, there are only 2 leaks found in their site, which are 450GB in total. Previously, the group had targeted a small Electronics Repair Firm based in the UK in the month of May, 2022.

It is interesting to note that the 0mega had leaked (whole) 100% files of Maxey Moverley (initial victim) on 23rd May, 2022 at single go. But in the case of Nextlabs; the operators had split the data breach in 3 time frames, allowing enough time for the company to respond/negotiate to their ransom demand.

10% leaked on 15th September, 2022: 29.9GB
60% leaked on 27th September, 2022: 137.1GB
100% leaked on 3rd October 2022: 298GB

From this, it can be assumed that Threat Actors had spent 18 days on their second victim.

POSSIBLE ASSOCIATION (Can’t Say!)

Upon Researching similar incident, it came to light that there was another Ransomware named “Omega” which was under development in June 2019. However, as the files were appended with extension “.dodger” it came to be known as Dodger Ransomware. The reason to call it Omega initially is because actors email address: omegax0@protonmail.com.

As per the tweet, it clearly shows that this ransomware is in the development stage and does not support Encryption.

Twitter Post on Dodger Ransomware

It is observed that 0mega Ransomware Group is slow as compared to other counterparts, but they are improving gradually by improving their strategies. More information could be drawn after obtaining the ransomware samples.
