Lazarus Group Tied to TFlower Ransomware

The Lazarus Group, a North Korean hacking operation also known as Hidden Cobra, is deploying TFlower ransomware, using its MATA malware framework, security firm Sygnia reports.

The group has been using the MATA framework to deliver payloads since 2019, according to previous reports from security firms Kaspersky and NetLabs (see: Lazarus Group Deploying Fresh Malware Framework).
