Disclosure context

About Abyss

Abyss is a relatively new ransomware group that emerged in March 2023, operating with primarily financial motivations and targeting organizations across multiple sectors with a focus on English-speaking countries. The group's origin and affiliations remain largely undocumented by major security agencies, though their targeting patterns suggest they operate independently rather than as a Ransomware-as-a-Service model. Their attack methodology and specific tools have not been extensively documented by major threat intelligence firms, though their victim profile of 87 organizations indicates they employ effective initial access techniques to compromise business services, technology, healthcare, and agriculture sectors. The group demonstrates a clear geographic preference for targets in the United States, United Kingdom, Canada, Switzerland, and Hong Kong, suggesting either language preferences or specific regional access capabilities. Due to the group's recent emergence and relatively limited public documentation from established security researchers, detailed information about notable campaigns, encryption methods, or law enforcement actions remains scarce. Abyss appears to remain active as of current reporting, though the lack of extensive public analysis by major threat intelligence organizations suggests they may operate at a smaller scale compared to more prominent ransomware families. The group has been linked to 103 public disclosures across our corpus. First observed on a leak site on March 21, 2023; most recent post June 7, 2026. The operation is currently active.

If your organisation is affected

A listing by Abyss means bienvilleortho.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 Abyss'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.
