Sivatel Bangkok Data Breach

Sivatel Bangkok, a telecommunications company based in Thailand, has been listed as a victim on the Qilin ransomware group’s dark web portal, with the entry published on June 21, 2026. This listing was identified through SOCRadar’s Dark Web Monitoring service. In the 60 days prior to this listing, Qilin has claimed approximately 202 other victims, frequently targeting the Manufacturing, Business Services, and Construction sectors, particularly in the United States, United Kingdom, and Australia. Sivatel Bangkok joins other recent Qilin victims such as SatCom CX, Lifeline PCS, Isuzu Motors, and NR Engineering Co., Ltd., indicating a broad current campaign by the group.

SOCRadar’s initial-access correlation against stealer-log telemetry returned no direct records for www.sivatelbangkok.com. However, this absence does not guarantee the absence of a breach. Potential factors include the actor using alternate domains, harvesting credentials via personal email aliases, or logs being rotated before indexing. The typical initial access vector for ransomware groups like Qilin involves using credentials harvested by information stealers from underground marketplaces. These credentials are then used to access corporate networks via services like Microsoft 365 or VPNs, before deploying ransomware. CTI teams are advised to continue monitoring and implement proactive credential-hygiene checks, rather than assuming no exposure based on a null query result.
