Darkfield

Operator dossier

devman is a ransomware operator currently active on public leak sites. Darkfield has indexed 184 public victims claimed by this operator between April 6, 2025 and February 4, 2026. 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.

How we know this. Operator profiles on Darkfield are built from continuous monitoring of every leak site the group is known to operate, cross-correlated with community-curated feeds (RansomLook, ransomware.live, RansomWatch, MISP-galaxy). Status flips from active to inactive when no new disclosure appears for 60 days. MITRE ATT&CK mappings shown in the interactive section below are sourced from CISA, vendor analysis, and the MITRE community catalog — we attribute each technique back to its source. Aliases reflect operator re-brands and affiliate splits.
