On July 25, 2026, the Thailand Securities Depository (TSD) detected an unauthorized access incident involving its TSD Investor Portal. According to a report by Khaosod Online, TSD management and the Cyber Crime Investigation Bureau (CCIB) confirmed on July 28 that the breach compromised the personal information of roughly 200,000 individuals out of a total user base of over 5 million.
