MandarinBank

In February 2023 the threat actor group known as NLB leaked data from the MandarinBank payment system. The breach involved approximately 16 thousand user records and a larger dataset containing 2.7 million transaction logs or checks. The leaked information includes sensitive credentials such as email addresses and passwords along with detailed financial transaction history. This incident highlights vulnerabilities in payment processing security and exposes users to potential phishing and account takeover attacks.
