Poland: Hackers Attacked Water Treatment Plants — Threat to Water Infrastructure

Colleagues, I want to highlight a cybersecurity concern: Poland’s Internal Security Service detected attacks on five water treatment plants, where attackers may have accessed industrial control systems and affected water quality.

- Essence: intelligence neutralised sabotage attempts; perpetrators not disclosed.
- Similar threat: in the US in 2021 an intruder tried to alter water chemistry at Oldsmar; federal agencies warn of weak protection at water utilities.
- Trend: PLCs and control systems at water and power facilities are being targeted.

Why it matters: critical‑infrastructure vulnerabilities risk public health and system resilience.

Which protective measures for critical infrastructure do you consider priorities?
