The North Korean hacking group Andariel is linked to the Play ransomware operation, potentially as an affiliate or initial access broker. Researchers found they compromised a network to deploy Play ransomware. This collaboration may help evade sanctions, similar to tactics used by other sanctioned groups like Evil Corp and Iranian hackers.
### Meeting Takeaways: North Korean Hacking Group ‘Andariel’ Linked to Play Ransomware Operation
