Disclosure context

About blackwater

Based on the limited available data, Blackwater is an obscure ransomware operation that first emerged in April 2026, with only one documented victim to date, suggesting either a very new or small-scale financially motivated cybercriminal group. The group appears to operate primarily in Turkey, specifically targeting the healthcare sector based on their singular known attack. Due to the extremely limited public documentation and recent emergence timeframe, detailed information about their attack methodology, tools, encryption techniques, or operational structure remains unavailable from established threat intelligence sources such as CISA, FBI, or major security research firms. No notable high-profile campaigns, significant ransoms, or law enforcement actions have been publicly documented against this group. Given the recent April 2026 first observation date and lack of comprehensive threat intelligence reporting, the current operational status and capabilities of Blackwater remain largely unknown to the broader cybersecurity community. The group has been linked to 15 public disclosures across our corpus. First observed on a leak site on April 12, 2026; most recent post August 26, 2026. The operation is currently active.

Also tracked as: BLACK WATER.

If your organisation is affected

A listing by blackwater means Unknown (second listing) appeared on a ransomware extortion site and is being pressured to pay before any publication. 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 blackwater'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.
