Sivatel Bangkok was listed by the qilin ransomware group on June 21, 2026, after internal files were exfiltrated in a ransomware attack. An undisclosed number of people may have been affected; anyone connected to the hotel should check their status and take protective steps.
Breaking down the breach
The only confirmed public detail is the group’s listing of Sivatel Bangkok. The reported date is June 21, 2026. No timeline for the underlying intrusion, no attack method, and no volume of data have been disclosed. The number of people affected is listed as unknown.
Who is qilin?
Qilin is a ransomware-as-a-service operation that first appeared in public reporting in 2022. The group typically gains access through compromised remote-access services or phishing, then deploys encryption while also copying selected files. It maintains a leak site where it lists organizations and posts samples of claimed data when ransom negotiations fail. Public records show the group has targeted entities across multiple countries and sectors in prior incidents.
About Sivatel Bangkok
Sivatel Bangkok operates as a hotel in Thailand’s hospitality sector. Organizations of this type routinely collect and store guest registration records, booking histories, and operational documents. A breach involving such an entity can expose information that individuals provided when making reservations or during their stay.
What was likely exposed
The listing describes “internal files exfiltrated in ransomware attack.” No further breakdown of file categories or record counts has been published. The exact contents therefore remain unconfirmed.
- Guest names and contact details typically held by hotels
- Reservation and payment records
- Internal operational or administrative documents
What's at stake
Individuals whose information appears in the exfiltrated files could face follow-on risks such as phishing attempts or misuse of contact data. For the organization, the incident adds the possibility of regulatory scrutiny and operational disruption while the full extent of access is investigated. Both outcomes depend on details that have not yet been made public.

Publicly posted by qilin — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
