A threat actor has allegedly leaked a massive trove of sensitive customer and payment data implicating several major financial, telecommunications, and technology firms across Asia. The data leak reportedly stems from a dispute over a penetration test conducted on RedDotPayment, a major Singapore-based payment gateway owned by global fintech giant PayU. The actor claims they are now selling the data after the company refused to honor a prior agreement. The breach potentially affects customers of RedDotPayment and other major companies, including Thailand’s fifth-largest bank, Krungsri (Bank of Ayudhya), the state-owned National Telecom of Thailand, and the Taiwanese online security and payment solutions firm, HiTRUST Inc.
The implicated companies are significant players in their respective markets. RedDotPayment is a critical component of the e-commerce infrastructure in Southeast Asia, processing online transactions for a vast network of merchants. The alleged involvement of Krungsri, a systemically important bank in Thailand, and National Telecom, a major Thai telecommunications provider, widens the potential impact to a large base of banking and telecom customers. Furthermore, the inclusion of HiTRUST, a company specializing in online transaction security, is particularly concerning. Given the nature of the exposed data, this incident poses a severe risk of financial fraud, identity theft, and other malicious activities targeting the affected individuals.
The leaked data samples appear to be raw transaction records containing highly sensitive personal and financial information. If the full database is as comprehensive as the samples suggest, the consequences for consumers could be severe. An analysis of the allegedly leaked information indicates it includes the following:
- Full Customer Names
- Contact Information (Email and Phone Numbers)
- Complete Credit Card Numbers
- Credit Card Expiry Dates
- Credit Card CVV Security Codes
- Transaction Details (Amount, Currency, Merchant Name)
- Customer’s IP Address and Browser Information
