Disclosure context

About bert

The "bert" ransomware group is a recently emerged threat actor first observed in April 2025, appearing to be financially motivated based on their ransomware operations targeting multiple sectors across several countries. Given the limited public documentation and recent emergence, the group's origin and affiliations remain unclear, though their targeting pattern suggests either independent operations or a small-scale ransomware-as-a-service model. With only seven documented victims to date, specific details about their attack methodology, initial access vectors, and encryption techniques have not been extensively documented by major security firms or law enforcement agencies. The group has demonstrated a diverse targeting approach, focusing primarily on organizations in the United States, Malaysia, Taiwan, the United Kingdom, and Turkey, with victims spanning technology, business services, healthcare, and transportation/logistics sectors. No major high-profile campaigns or significant law enforcement actions have been publicly reported against this group, likely due to their recent emergence and relatively small scale of operations. The group appears to remain active as of their recent first observation, though their limited victim count and lack of extensive public documentation suggest they are either a nascent operation or a low-profile threat actor that has not yet attracted significant attention from major cybersecurity researchers or government agencies. The group has been linked to 7 public disclosures across our corpus. First observed on a leak site on April 6, 2025; most recent post June 10, 2025. The operation is currently inactive.

If your organisation is affected

A listing by bert means Columbia TI 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 bert'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.
