Disclosure context

About BYOD

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. The group has been linked to 5 public disclosures across our corpus. First observed on a leak site on October 5, 2026. The operation is currently active.

If your organisation is affected

A listing by BYOD means Royal Selangor appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

  • Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
  • Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
  • Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
  • Monitor for the data appearing on BYOD's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
