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 6 public disclosures across our corpus. First observed on a leak site on April 12, 2026; most recent post May 2, 2026. The operation is currently active.
