The attack was disclosed on January 24, 2026, when MRC Prion Unit and Institute of Prion Diseases appeared on the group's dark web leak site.

MRC Prion Unit and Institute of Prion Diseases is based in United Kingdom , operating in the Healthcare sector. United Kingdom ranks #4 globally for ransomware attacks, with 846 victims in our database.

Sector context: Healthcare organisations are high-value ransomware targets because patient data is extremely sensitive, regulatory penalties for breaches are severe, and operational downtime can threaten patient safety โ€” all factors that increase ransom payment pressure.

Crypto24 typically employs a double extortion model: first exfiltrating sensitive data from the victim's systems, then deploying ransomware to encrypt files. Victims face two simultaneous threats โ€” paying to restore access and paying to prevent publication of stolen data. The group's leak site publishes victim names and exfiltrated data as leverage.
