Disclosure context

About Fog

Fog is a relatively new ransomware group that emerged in July 2024, operating with apparent financial motivations and demonstrating rapid expansion in their victim targeting across multiple geographic regions and industry sectors. The group's origin and specific affiliations remain unclear due to their recent emergence, though their operational patterns suggest they likely operate independently rather than as part of an established Ransomware-as-a-Service ecosystem. Given the limited public documentation from major security agencies and researchers due to the group's recent appearance, specific details about their attack methodology, initial access vectors, and encryption techniques have not yet been comprehensively analyzed or reported by authoritative sources such as CISA, FBI, or major threat intelligence firms. The group has reportedly victimized 189 organizations primarily across the United States, Germany, France, Australia, and Brazil, with their attacks predominantly targeting the technology sector, followed by education, business services, and manufacturing industries, though no specific high-profile campaigns or record ransom demands have been publicly documented by major security researchers at this time. As of current reporting, Fog appears to remain active given their recent emergence and ongoing victim acquisition patterns observed throughout 2024. The group has been linked to 189 public disclosures across our corpus. First observed on a leak site on July 16, 2024; most recent post March 20, 2025. The operation is currently inactive.

If your organisation is affected

A listing by Fog means WDNA 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, INCIBE-CERT (Spain), as required for your jurisdiction.
Monitor for the data appearing on Fog'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.
