teamxxx is a ransomware operator no longer publishing new disclosures. Darkfield has indexed 12 public victims claimed by this operator between June 10, 2025 and August 4, 2025. Based on the limited available information, teamxxx is a recently emerged ransomware group first observed in June 2025, appearing to be financially motivated based on their targeting patterns and operational characteristics. The group's origin and potential affiliations remain unclear due to their recent emergence and limited public documentation by major threat intelligence organizations. Their attack methodology and specific tools have not been extensively documented, though their diverse geographic targeting across the United States, Czech Republic, Hong Kong, Sweden, and Germany, combined with their focus on high-value sectors including healthcare, financial services, and hospitality suggests a financially-driven operation seeking maximum impact and payment potential. With only 12 known victims documented since their emergence, the group has not yet conducted any widely-publicized major campaigns that have drawn significant attention from law enforcement or security researchers. Given their recent first observation in June 2025, teamxxx appears to still be active, though their limited victim count and lack of extensive public reporting suggests they remain a relatively minor player in the current ransomware landscape.
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.
