PEAR, also known as Pure Extraction and Ransom, is a financially motivated cybercriminal ransomware and extortion group that emerged publicly in mid-2025. It conducts data-theft extortion: operators exfiltrate victim data and threaten its publication unless a ransom is paid, using a dedicated leak site to name victims and release purported stolen material. PEAR has claimed intrusions affecting organizations primarily in the United States and Jamaica, including healthcare providers and healthcare-service companies. Its claims have included theft of patient, insurance, employee, financial, and business-operational data. A disclosed breach at a U.S. healthcare revenue-cycle-management provider was subsequently claimed by PEAR, although the group’s asserted data volume and the authenticity of material it said it possessed were not independently verified. PEAR has also claimed victims in technology and telecommunications, manufacturing, energy services, legal services, hospitality, food and beverage services, and nonprofit organizations. Publicly available reporting does not establish PEAR’s geographic origin, malware implementation, initial-access methods, or use of file encryption.
