Disclosure context

About DYSPHOR1A

DYSPHOR1A is a ransomware group first observed in August 2026 with an apparent financial motivation, having claimed at least five known victims across Southeast Asia since its emergence. The group has demonstrated a regional targeting focus, with activity concentrated in Myanmar, Thailand, and Indonesia, and has shown a preference for high-value sectors including education, government and defense, professional services, and financial services. Due to the group's limited operational history and small victim count at the time of this profile, detailed technical attribution regarding country of origin, RaaS infrastructure, or affiliation with established threat actor ecosystems has not been publicly confirmed by CISA, the FBI, Mandiant, or other reputable security research organizations. Similarly, specific details regarding initial access vectors, tooling, encryption methodology, and extortion tactics remain undocumented in open-source intelligence, though the sectors targeted suggest an adversary with interest in sensitive data environments that may support double extortion operations. No major high-profile campaigns, record ransom demands, or law enforcement actions against DYSPHOR1A have been publicly documented as of this writing. DYSPHOR1A should be considered an emerging and closely monitored threat actor, with its limited but geographically and sectorally consistent targeting pattern warranting continued observation by regional defenders and threat intelligence teams. The group has been linked to 21 public disclosures across our corpus. First observed on a leak site on August 20, 2026; most recent post September 5, 2026. The operation is currently active.

If your organisation is affected

A listing by DYSPHOR1A means Myanmar Broadband Telecom Co., Ltd. (MBT) 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 DYSPHOR1A'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.
