The UK's National Cyber Security Centre warns the country could face large-scale hacktivist attacks if drawn into a conflict, with potential impact matching recent major ransomware incidents.

Richard Horne, chief executive of the NCSC, cautioned that nation states represent the most significant cyber threats facing the UK currently. However, hacktivist groups could pose a serious secondary risk during periods of international tension or conflict. The warning highlights how cyber attacks have evolved from isolated incidents to coordinated campaigns capable of disrupting critical infrastructure and essential services. Recent high-profile ransomware attacks have demonstrated the scale of damage possible, affecting healthcare systems, utilities, and government operations. The NCSC's alert comes as geopolitical tensions remain elevated globally. Officials stress the need for heightened vigilance among critical infrastructure operators and private sector organizations to strengthen defenses against potential coordinated attacks. The agency continues advising organizations to implement robust security protocols, including regular backups, multi-factor authentication, and incident response planning to mitigate risks from both state-sponsored and hacktivist threats.
