Disclosure context

About krybit

Krybit is an emerging ransomware group that was first observed in April 2026, operating with apparent financial motivations based on their limited documented attacks against diverse sectors. The group's origin and affiliations remain unclear due to limited public intelligence, and it is unknown whether they operate as a Ransomware-as-a-Service model or as an independent entity. With only four known victims documented across geographically diverse regions including Mexico, Austria, Japan, and Botswana, the group appears to employ broad targeting rather than focused regional or sector-specific campaigns, though their attack methodology, encryption techniques, and data exfiltration practices have not been publicly documented by major security firms or law enforcement agencies. No notable high-profile campaigns or significant ransoms have been publicly reported, and no law enforcement actions against the group have been documented. Given the recent emergence of this group and extremely limited public reporting, Krybit's current operational status and capabilities remain largely unknown to the broader cybersecurity community. The group has been linked to 89 public disclosures across our corpus. First observed on a leak site on April 3, 2026; most recent post August 2, 2026. The operation is currently active.

If your organisation is affected

A listing by krybit means www.prohealth.sg 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, SingCERT (Singapore), as required for your jurisdiction.
  • Monitor for the data appearing on krybit'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.
