Darkfield

Operator dossier

ExfilSquad is a ransomware operator currently active on public leak sites. Darkfield has indexed 42 public victims claimed by this operator between July 26, 2026 and August 18, 2026. ExfilSquad is a relatively nascent ransomware group first observed in July 2026 with a confirmed victim count of 14, operating with an apparent financial motivation consistent with contemporary cybercriminal ransomware operations. The group's country of origin and potential affiliations with known threat actor clusters or ransomware-as-a-service ecosystems have not yet been publicly attributed by CISA, FBI, Mandiant, or other reputable security research organizations, and details regarding their operational infrastructure remain limited in open-source reporting. Based on observed targeting patterns, ExfilSquad has demonstrated a preference for high-value sectors including Government and Defense, Technology, Financial Services, Education, and Transportation, with victim organizations concentrated primarily in the United States and Great Britain, and additional targeting observed in Sweden and Nigeria, suggesting a financially motivated group comfortable operating across multiple jurisdictions rather than one with a narrowly defined geopolitical focus. Given the group's recent emergence and relatively limited victim count, detailed technical indicators regarding their specific initial access vectors, tooling, encryption implementation, or use of double-extortion data leak sites have not been comprehensively documented in publicly available threat intelligence reporting at this time. As of the time of this profile, no significant law enforcement actions, disruptions, or confirmed rebranding activity associated with ExfilSquad have been publicly disclosed, and the group should be considered potentially active given the recency of their first observed activity.

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.
