Locky is an early, high-volume ransomware operation that became prominent around 2015 and is widely associated with the earlier phase of commodity ransomware before the rise of enterprise-focused big-game hunting. It was commonly distributed through large-scale malicious email campaigns using attachments, and typically sought relatively small payments from individual victims or single machines rather than conducting the later-style full-enterprise extortion seen in more modern ransomware ecosystems. Locky is frequently referenced as representative of the transition point between opportunistic mass ransomware and the more specialized criminal market that later evolved into affiliate-driven ransomware-as-a-service and double-extortion operations. High-confidence reporting in this context supports Locky as ransomware focused on encrypting victim systems for payment, but does not directly establish additional actor-attribution details, country of origin, or specific targeting by geography or industry.
