Disclosure context

About blacklock

Based on the limited publicly available information, Blacklock is an emerging ransomware group first observed in May 2025, operating with apparent financial motivations targeting organizations across multiple countries and sectors. The group's origin and potential affiliations remain unclear from documented sources, and there is insufficient public reporting to determine whether they operate as a Ransomware-as-a-Service model or as an independent entity. With 64 documented victims since their emergence, Blacklock has demonstrated a broad targeting approach across the United States, Canada, Spain, India, and the United Kingdom, with particular focus on technology, construction, manufacturing, and consumer services sectors, though their attack methodology, initial access vectors, and encryption tactics have not been extensively documented by major security research organizations. Due to the group's recent emergence and limited public reporting from established threat intelligence sources, notable campaigns and specific technical details of their operations remain largely undocumented in publicly available security research. As of current reporting, the group appears to remain active given their recent emergence date, though comprehensive analysis of their operational status requires additional documentation from established cybersecurity authorities. The group has been linked to 64 public disclosures across our corpus. First observed on a leak site on May 16, 2025; most recent post July 2, 2025. The operation is currently inactive.

If your organisation is affected

A listing by blacklock means PC AfterHours 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 blacklock'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.
