What happened
ePUAP handles electronic submissions and mailboxes for public offices across Poland. The digital affairs minister announced on November 10 that officials detected and stopped an attack and that Poland’s Internal Security Agency joined the investigation. A ministry spokesperson described the shutdown as a safety measure in an interview with Onet. The public statements do not identify an exploit, affected versions, stolen data or a confirmed attacker. The national impact comes from loss of access to the filing service.
