Ryuk is a crypto-ransomware strain that encrypts access to a system, device, or file through malware and demands ransom to release it.
Security Agencies CISA (Cybersecurity and Infrastructure Security Agency), FBI, and the Department of Health and Human Services (HHS) have issued a high alert joint security advisory to hospitals to take actions to secure themselves from Ryuk ransomware in particular.
We analyzed three ransomware incidents (Ryuk, Revil & AKO) and found 16 CVEs associated with them. Incidentally, CSW warned about five of these CVEs in our cyber risk series way back in March 2020!
