About qilin

Qilin is a ransomware group that emerged in October 2022, operating with primarily financial motivations through targeted attacks against organizations across multiple sectors. The group appears to operate independently with limited public information available regarding their specific country of origin or affiliations to other ransomware families. Qilin employs double extortion tactics, typically exfiltrating sensitive data before deploying their encryption payload, though specific details about their initial access vectors and technical tools remain less documented in public security research. The group has demonstrated a broad targeting approach, with their 1645 known victims spanning multiple countries including the United States, France, Canada, United Kingdom, and Germany, with particular focus on manufacturing, technology, healthcare, and business services sectors. Based on available intelligence reporting, Qilin remains an active threat as of recent assessments, continuing their ransomware operations without significant reported law enforcement disruption. The group has been linked to 1,858 public disclosures across our corpus. First observed on a leak site on October 8, 2022; most recent post May 21, 2026. The operation is currently active.
