Disclosure context

About linkc

Given the extremely limited public documentation available, linkc appears to be a newly emerged or minor ransomware operation first observed in February 2025, with only one documented victim to date. The group demonstrates a focus on the technology sector within the United States, though their country of origin, operational structure, and affiliations remain unknown due to insufficient intelligence reporting from major cybersecurity organizations and law enforcement agencies. Without documented analysis from CISA, FBI, Mandiant, or other reputable security researchers, the group's attack methodology, initial access vectors, encryption techniques, and extortion tactics cannot be definitively characterized. No notable campaigns, high-profile victims, or significant ransoms have been publicly reported for this group. The current operational status of linkc remains unclear due to the lack of comprehensive threat intelligence reporting on their activities. The group has been linked to 4 public disclosures across our corpus. First observed on a leak site on February 19, 2025; most recent post April 8, 2026. The operation is currently active.
