Operator dossier

BYOD is a ransomware operator currently active on public leak sites. Darkfield has indexed 5 public victims claimed by this operator between October 5, 2026. BYOD is a nascent ransomware group first observed in October 2026 with limited public documentation available from major threat intelligence sources at this time. The group has claimed or been attributed to three known victims, with targeting patterns indicating a focus on the Technology and Manufacturing sectors, with Malaysia and the United States representing their primary geographic targets. Due to the group's recent emergence and low victim count, no detailed attack methodology, tooling, or initial access vectors have been publicly documented by CISA, FBI, Mandiant, or equivalent reputable security research organizations as of this profile's compilation. No notable high-profile campaigns, record ransom demands, or law enforcement actions have been publicly attributed to BYOD, and their operational model — whether independent or RaaS-based — remains unconfirmed in open-source reporting. The group should be considered an emerging threat under active monitoring, with their targeting of dual geographies across Southeast Asia and North America warranting continued observation as their operational tempo and tactics may become clearer with additional victim disclosures or researcher attribution.

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 changes from active to dormant when no new disclosure appears for 60 days. Without a disclosure date, activity is unknown. 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.
