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.

If your organisation is affected

A listing by linkc means StrongLink 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.
Monitor for the data appearing on linkc'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. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
