Disclosure context

About blacknevas

Blacknevas is an emerging ransomware group that was first observed in August 2025, appearing to be primarily financially motivated based on their targeting patterns and operational characteristics. The group's origin and potential affiliations remain unclear due to limited public documentation from established threat intelligence sources, though their diverse geographic targeting suggests either a distributed operation or broad opportunistic approach. Based on available victim data, Blacknevas has compromised at least 23 organizations across multiple countries, with the United States, Spain, India, Japan, and Thailand being the most frequently targeted nations, while their sector focus spans technology, manufacturing, energy, and consumer services industries, suggesting they employ opportunistic rather than sector-specific targeting methodologies. The group's attack vectors, specific tools, and whether they operate as a Ransomware-as-a-Service model or maintain independent operations have not been publicly documented by major cybersecurity firms or government agencies. Due to the group's recent emergence in August 2025, there is insufficient public reporting from established sources like CISA, FBI, or major threat intelligence providers to detail notable campaigns or significant attacks beyond the confirmed victim count. Given the recency of their first observed activity, Blacknevas appears to remain active as of late 2025, though comprehensive threat intelligence profiles from authoritative sources have yet to be published. The group has been linked to 31 public disclosures across our corpus. First observed on a leak site on August 6, 2025; most recent post April 30, 2026. The operation is currently active.
