Disclosure context

About chaos

Based on the limited publicly available information, Chaos is a recently emerged ransomware group that was first observed in March 2025, appearing to be financially motivated given their ransom demands and targeting patterns. The group's origin and specific affiliations remain unclear due to their recent emergence, though their operational model and whether they operate as Ransomware-as-a-Service or as an independent entity has not been definitively established by security researchers. Their attack methodology and specific technical capabilities are not yet well-documented in public threat intelligence reports, though their targeting suggests they employ common initial access vectors to compromise victims across multiple sectors. Chaos has claimed 41 victims primarily concentrated in the United States, Germany, Poland, Malaysia, and Sweden, with a particular focus on technology companies, financial services, business services, and manufacturing sectors, though the scope and impact of their most significant attacks have not been widely publicized. The group currently appears to be active based on recent victim claims, though comprehensive analysis from major security firms regarding their long-term operational capabilities and potential law enforcement actions remains limited due to their recent emergence in the threat landscape. The group has been linked to 53 public disclosures across our corpus. First observed on a leak site on March 31, 2025; most recent post May 17, 2026. The operation is currently active.
