title: "Default Credentials and Missing MFA: Inside the Poland Energy Cyberattack"
description: "This major incident in Poland is a useful reminder that attackers don't always need \"clever\" exploits - they often just need easy access.
On 29 December 2025, coordinated destructive cyberattacks hit 30+ wind and solar sites in Poland and a large Combined Heat-and-Power (CHP) plant serving nearly half a million customers. The focus was on operational visibility and recoverability rather than electricity generation itself."
