PEAR, also tracked as pear and pear_ransomware_group, is a financially motivated cybercriminal extortion group first publicly observed in mid-2025. It operates an extortion-only model centered on stealing organizational data and threatening publication unless a ransom is paid. Although frequently categorized as a ransomware group, its established operating model does not require file encryption. PEAR uses phishing and voice phishing to gain access to Microsoft 365 email accounts. Its core capabilities include initial access, data exfiltration, and extortion. Its reported targeting spans the United States and Jamaica, with healthcare organizations prominently represented alongside retailers, hospitality businesses, professional-services firms, technology providers, coatings manufacturers, and energy-industry service providers. Healthcare targets include outpatient and urgent-care providers, pharmacies, and healthcare technology businesses. Public victim listings and extortion claims do not independently establish the extent of individual compromises, data-loss volumes, or deployment of encryption malware.
