Poland's Internal Security Agency has detected attacks on five water treatment plants where hackers could have taken control of industrial equipment, including tampering with the safety of the water supply.
The report said Polish intelligence thwarted multiple acts of sabotage from Russian government spies and hackers targeting military facilities, critical infrastructure, and civilian targets.
Poland's experience is part of a growing global pattern of attacks on water and energy infrastructure, with Iranian-backed hackers also targeting U.S. utilities.
The attacks against Poland follow a strategy by the Russian government to destabilize and weaken the West through cyberattacks and cyberespionage.
