FortiGuard Labs was investigating the Sodinokibi ransomware family, when we came across the newly discovered Nemty Ransomware. Interestingly, as we analyzed this new malware, we also encountered an artifact embedded in its binary that we were very much familiar with since it was also used by the GandCrab ransomware before the threat actors’ announced retirement. It is also interesting to see that the Nemty ransomware is being distributed using the same method as Sodinokibi, a malware that has strong similarities to GandCrab.
