Increase in Ryuk ransomware attacks
CERT NZ is aware of a spike in Ryuk ransomware attacks in the United States. The attacks are encrypting the systems of numerous organisations in the health care sector, and demanding ransoms, averaging over USD$100,000 to be paid in bitcoin for the decryption of information.
While this campaign is currently affecting United States based organisations, CERT NZ is encouraging New Zealand organisations to make sure they have the protections in place to help protect against an attack.
