Disclosure context

About Interlock

Interlock is a recently emerged ransomware group that began operations in October 2024, primarily motivated by financial gain through extortion activities targeting organizations across multiple sectors. The group's country of origin and potential affiliations remain unclear given their recent emergence, with insufficient public documentation to determine whether they operate as an independent entity or under a Ransomware-as-a-Service model. Limited public information exists regarding their specific attack methodologies, initial access vectors, or encryption techniques, as major cybersecurity firms and law enforcement agencies have not yet published comprehensive technical analyses of their operations. Since beginning operations, Interlock has reportedly compromised approximately 100 victims, with their targeting primarily focused on organizations in English-speaking countries including the United States, Canada, United Kingdom, and Australia, as well as Italy, while demonstrating a preference for attacking education, manufacturing, healthcare, and public sector entities. The group remains active as of late 2024, though comprehensive threat intelligence profiles from established security research organizations have not yet been published due to the group's recent emergence in the threat landscape. The group has been linked to 114 public disclosures across our corpus. First observed on a leak site on October 13, 2024; most recent post July 10, 2026. The operation is currently active.

If your organisation is affected

A listing by Interlock means Brockton Neighborhood Health Center 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, CISA (United States), as required for your jurisdiction.
Monitor for the data appearing on Interlock'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.
