Disclosure context

About blackshrantac

Based on available intelligence, blackshrantac is a recently emerged ransomware group first observed in September 2025, operating with apparent financial motivations and demonstrating a geographically diverse targeting approach across multiple continents. The group has victimized 43 known entities primarily across India, the United States, Turkey, Peru, and Australia, suggesting either a broad opportunistic targeting strategy or access to varied initial compromise vectors that span different regions. Their sector targeting shows a preference for manufacturing, technology, financial services, and public sector organizations, though a significant portion of their attacks have occurred against entities in unspecified sectors, indicating either incomplete intelligence gathering or deliberate obfuscation of their targeting patterns. Due to the group's recent emergence and relatively limited public exposure, detailed information about their specific attack methodologies, tooling, encryption techniques, data exfiltration practices, or operational structure remains largely undocumented by major threat intelligence organizations and law enforcement agencies. The group's current operational status appears to be active given their recent first observation date, though the limited intelligence available suggests they may be either a smaller operation or have successfully maintained a lower profile compared to more established ransomware groups. The group has been linked to 43 public disclosures across our corpus. First observed on a leak site on September 17, 2025; most recent post January 20, 2026. The operation is currently active.
