Darkfield

Operator dossier

Onyx is a ransomware operator no longer publishing new disclosures. Darkfield has indexed 28 public victims claimed by this operator between April 29, 2022 and November 21, 2022. Onyx is a ransomware group that emerged in April 2022, primarily motivated by financial gain through extortion operations targeting organizations across North and South America. The group's country of origin and potential affiliations with other ransomware operations remain undetermined based on publicly available threat intelligence. Onyx has demonstrated a preference for targeting government and transportation sector entities, with their attack methodology and technical capabilities including initial access vectors, encryption methods, and data exfiltration practices not comprehensively documented in open-source intelligence reports from major cybersecurity firms or government agencies. The group has compromised 28 known victims, with the majority of their operations concentrated in the United States, Brazil, and Mexico, suggesting either a geographic targeting preference or regional access capabilities. Due to Onyx being a relatively smaller ransomware operation with limited public documentation from established threat intelligence sources like CISA, FBI, or major security research organizations, detailed information about specific notable campaigns, ransom demands, or high-profile victim organizations has not been extensively reported in public threat assessments. The current operational status of the Onyx ransomware group remains unclear based on available open-source intelligence reporting.

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.
