Disclosure context

About devman

The devman ransomware group is a recently emerged threat actor that began operations in April 2025, demonstrating a financially motivated criminal enterprise with a focus on opportunistic targeting across multiple sectors and geographic regions. Given the group's recent emergence and limited public documentation, specific details regarding their country of origin, organizational structure, or potential affiliations with established ransomware-as-a-service operations remain unknown to major cybersecurity agencies and researchers. The group's attack methodology and technical capabilities have not been thoroughly documented by reputable security firms, though their targeting patterns suggest a broad opportunistic approach rather than highly specialized tactics. In the brief period since their emergence, devman has reportedly compromised 184 victims across diverse sectors including technology, healthcare, public sector organizations, and agriculture and food production, with primary targeting concentrated in the United States, France, Svalbard and Jan Mayen, Taiwan, and Thailand, though the inclusion of Svalbard and Jan Mayen in their targeting list may indicate data collection anomalies rather than actual operational focus on this remote Arctic territory. As of current reporting, devman appears to remain an active threat, though the lack of detailed technical analysis or law enforcement advisories suggests they may be operating at a relatively low profile compared to more established ransomware groups. The group has been linked to 184 public disclosures across our corpus. First observed on a leak site on April 6, 2025; most recent post February 4, 2026. The operation is currently active.

If your organisation is affected

A listing by devman means procure.com 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 devman'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.
