Warsaw/Washington. Cyberattacks targeting water treatment plants and industrial control systems are emerging as a serious threat to public safety and national security, with Poland reporting organised intrusions into several water facilities and the United States facing similar risks to its water and energy infrastructure.
Poland Reports Attacks on Water Treatment Plants
According to a report released by Poland’s Internal Security Agency, at least five water treatment facilities were targeted over the last two years. The agency said attackers attempted to infiltrate systems responsible for controlling water flow, chemical balance and supply operations.

Officials warned that the attacks were not limited to data theft but appeared aimed at critical operational systems. Security agencies said timely intervention prevented possible disruption to water quality, public health and essential civic services.
Critical Infrastructure Under Wider Threat
Poland’s security agency also reported intensified cyber activity targeting other critical sectors, including power grids, military installations, transportation systems and government networks. Officials described the pattern as part of a broader strategy of digital sabotage rather than isolated hacking attempts.
The report did not directly name any country. However, Poland has remained alert to suspected Russia-linked cyber activity, especially amid growing geopolitical tensions in Europe.
US Water and Energy Systems Face Similar Risks
The threat extends beyond Poland. In the United States, a 2021 incident at a water treatment facility in Oldsmar, Florida, saw hackers attempt to raise sodium hydroxide levels in the water supply. Operators detected the change in time and prevented a possible public safety crisis.
US agencies, including the FBI and the Cybersecurity and Infrastructure Security Agency, have warned that water and energy systems remain soft targets for foreign cyber attackers. American authorities have also reported Iranian-linked hacking attempts targeting programmable logic controllers used in water and energy facilities.
Cybersecurity experts warn that industrial networks connected to internet-based systems are becoming more vulnerable. If attackers gain control of such systems, they could disrupt water supplies, alter chemical levels or shut down operational networks. Experts say the rising threat reflects a shift toward hybrid digital warfare, where cyberattacks on essential infrastructure are used to destabilise nations and weaken public trust.
