Disclosure context

About AuditTeam

AuditTeam is a relatively obscure ransomware group that emerged in April 2026 and appears to be financially motivated based on their operational patterns. The group's origin and affiliations remain unclear due to limited public documentation, though their targeting of victims primarily across China, Hong Kong, Philippines, South Korea, and Thailand suggests possible regional focus or language capabilities in Asian markets. With only five documented victims to date, AuditTeam appears to operate as a smaller-scale ransomware operation, showing particular interest in manufacturing and technology sectors alongside unspecified target types. Due to the group's recent emergence and limited scale of operations, there are no publicly documented major campaigns, high-profile victims, or significant law enforcement actions against them by agencies such as CISA, FBI, or major security research firms. The group's current operational status remains unknown given the sparse public intelligence available, and their attack methodology, encryption techniques, and extortion tactics have not been comprehensively documented by reputable security researchers as of available reporting. The group has been linked to 18 public disclosures across our corpus. First observed on a leak site on April 8, 2026; most recent post August 26, 2026. The operation is currently active.

If your organisation is affected

A listing by AuditTeam means Demidov Steel Group 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.
  • Monitor for the data appearing on AuditTeam'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. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
