AU Small Finance Bank investigates alleged data breach on Salesforce

AU Small Finance Bank on Monday confirmed it is investigating a potential data security incident involving its Salesforce platform after a hacking group claimed to have accessed sensitive customer information. The alleged breach reportedly includes know-your-customer (KYC) records, loan documentation and other customer data.

In a statement, the bank stressed that its banking systems and services remain unaffected and fully operational. The lender said it has initiated a comprehensive investigation into the matter and is working with relevant authorities and cybersecurity experts to assess the scope and authenticity of the claims.
