Description

Interbank, a leading Peruvian financial institution, confirmed a data breach after a hacker leaked stolen customer data online. Formerly known as the International Bank of Peru, Interbank serves over 2 million customers. The bank stated, "Some client data has been exposed by an unauthorized third party. We have promptly deployed additional security measures to protect our clients' information and operations." Amid customer reports of service disruptions on the bank's mobile app and online platforms throughout the day, and a separate outage two weeks prior, Interbank assured that most operations have resumed, with deposits and financial products remaining secure. "Interbank guarantees the security of your deposits. Most channels are functioning, and we will restore full access after an exhaustive review," the bank said. A threat actor, identified as "kzoldyck," claims to be selling data stolen from Interbank on multiple forums. Allegedly, the stolen information includes personal and financial details of over 3 million customers—names, account numbers, birthdates, addresses, emails, IP addresses, credit card details, and even plaintext credentials. The threat actor also claimed access to 3.7 TB of sensitive data, including internal credentials, and that negotiations with Interbank’s management to prevent the data leak failed after the bank refused to pay. Interbank has not yet disclosed the full extent of the breach or the exact number of affected customers.
