Data leak at Californischer Bank: Attention customers! How to protect yourself!

On October 3, 2025, California International Bank issued a warning to its customers after a security violation was found. A hacker had access to an employee's email account, which happened between 11 and 12 September, 2024. The bank reacted immediately and started a comprehensive examination when it learned about the incident.

Further details about this incident have been known in the past few weeks. On August 29, 2025, it was found that the affected email account may contain personal information from customers. Despite the severity of the attack, there is currently no evidence that the compromised data has been used for identity theft or fraud.

Preventive measures for customers

In order to ensure the security of its customers, the bank offers free credit surveillance services. Experian Identityworks provide these and include a variety of useful functions. This includes the possibility of placing fraud warnings or security inquiries. Identity theft protection insurance, which covers certain costs and unauthorized electronic money transfers up to an amount of $ 1 million, is also included.

Customers who register for this service are entitled to a free credit report in order to better monitor their financial situation. The bank also recommends checking the account statements and credit reports for fraudulent activities regularly in order to identify possible damage at an early stage.

In view of the increasing frequency of cyber attacks, the bank gives another example of the need for the need for robust safety protocols and a quick reaction in crisis situations. The responsibility of taking care of personal data remains in the hands of the customers who should actively take care of their financial security.
