After discovering the intrusion, the agency alerted the respective authorities about the incident and launched an investigation to determine its consequences. According to the official statement, the entire POLSA network was disconnected from the Internet to ensure data security.
So far, the agency has neither disclosed any details of this attack, nor linked it to a specific hacker group.
Citing its sources at POLSA, The Register reports that “the attack appears to be related to an internal email compromise, and staff are being told to use phones for communication instead.”
Currently, the agency is working to restore the affected systems in collaboration with the Polish Computer Security Incident Response Team (CSIRT NASK) and the Polish Military Computer Security Incident Response Team (CSIRT MON); the investigation into the incident is underway.
