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 93 public disclosures across our corpus. First observed on a leak site on March 31, 2025; most recent post September 29, 2026. The operation is currently active.

If your organisation is affected

A listing by chaos means carolinaasthma.com appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
Report the incident to your national CERT, CISA (United States), as required for your jurisdiction.
Monitor for the data appearing on chaos's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim.

We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable.
