UK may face large-scale hacktivist attacks amid conflict, warns security chief

What happened: Richard Horne, head of the National Cyber Security Centre, warned that the UK could experience widespread hacktivist attacks if involved in a conflict, with impacts comparable to recent major ransomware incidents. He noted that nation states are now behind the most significant cyber threats the agency handles.

Why it matters:

  • Potential large-scale cyber disruptions could affect critical UK infrastructure and services.
  • Government, businesses, and the public may face increased cybersecurity risks during geopolitical tensions.

MNN Take: The warning highlights the growing role of state-sponsored cyber threats and the importance of preparedness against large-scale digital attacks in times of conflict.
