BSP Financial Group (ASX:BFL) identified unauthorized third-party access to its back-office non-customer-facing test environment for various systems, and it is working with external cybersecurity experts to respond to and investigate the incident, according to a Tuesday Australian bourse filing.

It completed the testing of customer-facing services in the production environment and found no residual threats. It does not believe there is any ongoing risk beyond the test environment.

Upon detecting the incident, the firm took containment action as a precautionary measure, disabling externally facing internet services, which affected a number of its services. This included significant disruption to internet banking across the group, excluding Fiji, and agency banking in Papua New Guinea.
