Disclosure context

About warlock

Warlock is an emerging ransomware group that first appeared in June 2025, primarily motivated by financial gain through extortion operations targeting organizations across multiple sectors. The group's origin and potential affiliations remain unclear due to limited public documentation from established threat intelligence sources, though their targeting pattern spans both Western nations and Russia, suggesting possible opportunistic rather than geopolitically-motivated operations. Based on available victim data, Warlock has demonstrated capability to compromise organizations across diverse sectors including technology, financial services, telecommunications, and healthcare, with their attack methodology and technical capabilities requiring further analysis by security researchers to establish definitive patterns regarding initial access vectors, encryption methods, or data exfiltration tactics. While the group has accumulated 78 documented victims across the United States, Japan, Russia, Great Britain, and Turkey within their initial months of operation, insufficient public reporting from CISA, FBI, or major security firms exists to detail specific notable campaigns, ransom demands, or high-profile incidents. Given the group's recent emergence in mid-2025, their current operational status and potential evolution remain under observation by the cybersecurity community. The group has been linked to 78 public disclosures across our corpus. First observed on a leak site on June 11, 2025; most recent post November 6, 2025. The operation is currently inactive.

If your organisation is affected

A listing by warlock means lactanet 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, CCCS (Canada), as required for your jurisdiction.
Monitor for the data appearing on warlock'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.
