The NCSC issued an alert telling critical national infrastructure (CNI) providers to act now against severe cyber threats, aiming to reduce the risk of disruptive attacks on essential services. The guidance urges operators to monitor threats and network activity, increase situational awareness, and harden network defences. It matters because the warned-for attacks could shut down critical operations, damage Industrial Control Systems (ICS), or erase data so recovery becomes impossible.
