What the group claims

rtaf.mi.th is the official portal of the Royal Thai Air Force, one of Asia's oldest air forces (founded November 2, 1913; independent since 1937), with ~46,000 personnel and 11 combat wings, now running a modern Odoo-based portal publishing financial reports, procurement plans, and White Papers on its "Unbeatable Air Force" roadmap to 2037. Its fleet spans 46 F-16s, 11 Gripen C/D, 13 F-5TH Super Tigris, Saab 340 Erieye AEW&C, C-130s, and a VIP fleet including an ex-Thai Airways A340-500. In July 2025 the RTAF fought its first combat since 1988 in the Thai-Cambodian border conflict, with its Gripens achieving the type's first-ever combat weapons launch. The centerpiece modernization is the Gripen E/F program: Thailand signed the $550M "Peace Burapha 1" contract in August 2025 — first in APAC — with deliveries from 2029 and 8 more jets sought toward a 12-aircraft squadron by 2037.

Disclosure context

About thegentlemen

thegentlemen is a ransomware group that emerged in September 2025, operating with apparent financial motivations based on their broad targeting of commercial sectors. The group has documented 267 victims across multiple countries, with primary focus on the United States, Thailand, France, Brazil, and India. Their targeting strategy demonstrates a preference for high-value sectors including manufacturing, technology, healthcare, and financial services organizations. Given the group's recent emergence and limited public documentation from established threat intelligence sources such as CISA, FBI, or major security research firms, specific details regarding their country of origin, operational structure, attack methodologies, encryption techniques, and whether they employ ransomware-as-a-service models remain unclear. The relatively high victim count of 267 in a short operational timeframe since September 2025 suggests either an aggressive campaign pace or potential inflation of victim numbers through affiliate operations, though without corroborating intelligence reports, the group's exact operational capabilities and notable campaigns cannot be definitively established. Current intelligence indicates the group remains active as of late 2025, though comprehensive threat profiling requires additional validated reporting from authoritative cybersecurity sources. The group has been linked to 961 public disclosures across our corpus. First observed on a leak site on September 9, 2025; most recent post October 10, 2026. The operation is currently active.

If your organisation is affected

A listing by thegentlemen means Royal Thai Air Force 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 thegentlemen'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.
