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 36 public disclosures across our corpus. First observed on a leak site on August 6, 2025; most recent post July 14, 2026. The operation is currently active.

If your organisation is affected

A listing by blacknevas means Paramount Health Services & Insurance TPA Pvt. Ltd 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, CERT-In (India), as required for your jurisdiction.
Monitor for the data appearing on blacknevas's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.
