LOKI is an Iranian-nexus cybercriminal ransomware and data-extortion operation active since at least December 2025. The operation evolved from cryptocurrency-wallet phishing and CTBC-themed financial phishing into data theft and public extortion, reusing infrastructure across these phases. LOKI operates a public leak site that uses victim countdown and leak-release functionality and has exposed victim data for download. Its known activity includes the alleged compromise of a U.S. financial-services company and theft of a large volume of sensitive personal and financial records affecting more than 30,000 individuals. Iranian nexus attribution is based on infrastructure-registration information associated with an Iranian maintainer. No aliases or distinct subgroups are established beyond the name LOKI.
