Summary

Sodinokibi was first spotted in April 2019, a few months before the GandCrab “retirement”. It was observed to have a variety of initial access:

  • Vulnerability (e.g. Oracle WebLogic Server vulnerability CVE-2019-2725)
  • Spearphishing with Attachment/Link
  • Drive-by Compromise
  • RDP / Valid Accounts

Around March 2020, it began the same practice of using stolen files as leverage for ransom payment as well. They published over 12 GB of stolen data allegedly belonging to a company named Brooks International for not paying the ransom during this time.

No observed relations with other malwares unlike other ransomwares, may have a variety of attack flows due to the RaaS nature.
