Disclosure context

About BlackLocks

BlackLocks is a ransomware group first observed in September 2026 with an apparent financial motivation, though limited public documentation exists given the group's recent emergence and low victim count. Based on available data, the group has claimed at least one known victim, with targeting activity concentrated in South Korea and focused on the manufacturing sector, suggesting a deliberate or opportunistic interest in industrial and production-oriented organizations. No authoritative public reporting from CISA, FBI, Mandiant, or equivalent reputable security research organizations has been indexed regarding this group's specific initial access vectors, tooling, encryption methods, or extortion tactics at this time, which is consistent with a newly identified or low-volume threat actor that has not yet attracted significant public analytical attention. The group's single documented victim and narrow geographic and sectoral footprint may indicate early-stage operations, limited operational capacity, or selective targeting. No notable high-profile campaigns, record ransom demands, or law enforcement actions against BlackLocks have been publicly documented. BlackLocks should be considered an emerging threat actor of uncertain capability and affiliation, warranting continued monitoring as additional victims or technical indicators may surface through subsequent reporting. The group has been linked to 1 public disclosures across our corpus. First observed on a leak site on September 5, 2026. The operation is currently active.

If your organisation is affected

A listing by BlackLocks means 광명산업(주) 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, KrCERT/CC (South Korea), as required for your jurisdiction.
  • Monitor for the data appearing on BlackLocks'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.
