Disclosure context

About Projectrelic

Projectrelic is a ransomware group that emerged in November 2022, operating with apparent financial motivations based on their targeting patterns and victim extortion activities. The group has been documented attacking 46 organizations primarily across the United States, United Kingdom, India, Germany, and France, with a focus on technology, manufacturing, construction, and education sectors, though many victims' sector classifications remain undocumented. Limited public intelligence exists regarding Projectrelic's country of origin, organizational structure, or potential affiliations with other cybercriminal groups, and it remains unclear whether they operate as an independent entity or utilize a ransomware-as-a-service model. Similarly, detailed information about their specific attack methodologies, initial access vectors, encryption techniques, or use of double extortion tactics has not been extensively documented by major threat intelligence firms or law enforcement agencies. The group has not been associated with any particularly high-profile attacks or record ransom demands that have garnered significant public attention from security researchers or government agencies. Based on available reporting, Projectrelic appears to maintain some level of operational activity, though comprehensive assessments of their current operational status are limited due to the relatively sparse public documentation surrounding this particular threat actor. The group has been linked to 46 public disclosures across our corpus. First observed on a leak site on November 11, 2022; most recent post November 9, 2025. The operation is currently inactive.

If your organisation is affected

A listing by Projectrelic means cisin.com 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 Projectrelic'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.
