The National Cyber Security Centre has issued an urgent alert to operators of Britain's critical infrastructure following coordinated cyber-attacks on Poland's energy systems in December. Jonathan Ellison, NCSC's director for national resilience, warned that attacks disrupting essential services aren't "far-fetched" and urged immediate action.

The warning covers energy, water, transport, health, and telecommunications sectors. NCSC defines severe threats as deliberate attacks aimed at shutting down operations, damaging industrial control systems, or erasing data to prevent recovery.

Recommended defenses include patching vulnerabilities, implementing multi-factor authentication, and strengthening network monitoring. The upcoming Cyber Security and Resilience Bill will help manage the UK's collective vulnerability against modern threats.
