SASI JSC Listed by thegentlemen Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
SASI JSC was listed by thegentlemen ransomware group on January 20, 2026 after internal files were exfiltrated in a ransomware attack. An undisclosed number of people may be affected; check any accounts or services linked to SASI JSC and monitor for suspicious activity.
Inside the incident
The only confirmed public information is the listing itself, reported on January 20, 2026. The group states that internal files were taken during a ransomware operation against sasi.vn. No figure for the volume of data, the number of records, or the exact timing of the intrusion has been released by the company or by investigators. The precise method of initial access also remains undisclosed.
Inside thegentlemen
Thegentlemen is a ransomware group that maintains a leak site to publish names of claimed victims. Such groups typically gain access through phishing, stolen credentials, or unpatched remote services, then exfiltrate data before deploying encryption. Public records show the group has previously listed organisations across multiple countries, though any specific statements about SASI JSC originate solely from the listing and have not been independently verified.
About SASI JSC
SASI JSC, operating as Saigon Auto Supporting Industry JSC, is a Vietnamese manufacturer founded in the 1970s. Its facilities are located in the Cu Chi Industrial Park in Ho Chi Minh City. The company specialises in OEM production of metal parts, components, and assemblies made to customer specifications rather than its own branded products. Organisations of this type routinely store design files, supplier contracts, quality-control records, and employee or partner contact information.
What data was at risk
The listing refers only to “internal files exfiltrated in ransomware attack.” No further breakdown of file types or data categories has been published. Companies in precision manufacturing commonly hold engineering drawings, production schedules, client specifications, and administrative records. The exact contents of any material allegedly taken from SASI JSC have not been confirmed.
The real-world impact
Exposure of internal manufacturing files can create competitive or contractual risks for the company and its customers. For individuals, the main concern is indirect: employee records, vendor contacts, or personal identifiers that may sit alongside operational data. Because the number of affected people is unknown, the practical consequences for any single person cannot yet be quantified.
What to do if you're exposed
Individuals who have worked with or for SASI JSC, or who receive services from its customers, should monitor their email accounts and financial statements for unusual activity. Enabling multi-factor authentication on any linked services and using unique passwords reduces further risk. Readers can run a free exposure scan of their email address against known breach data to check whether their information appears in public listings from this or other incidents.

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.
