The UK's National Cyber Security Centre (NCSC), part of GCHQ, published its 'State of the Cyber Nation' report warning that AI adoption by hostile actors is 'highly likely' to increase the scale and efficiency of attacks including ransomware, social engineering, and vulnerability exploitation within the next two years. NCSC CEO Dr Richard Horne argues the risk stems not from AI inventing new attack methods, but from AI's ability to discover and exploit longstanding, under-invested security weaknesses at unprecedented speed and scale—attributing this exposure to decades of organisations pursuing 'tech on the cheap.'
The report calls on UK organisations to urgently invest in foundational security: addressing technology under-investment, removing unnecessary internet-facing connectivity, and treating Cyber Essentials as a baseline rather than an end goal. It coincides with UK government funding announcements including £60 million for a national 'Cyber Shield', £70 million for a new National Exposure and Real-Time Vulnerability (NERV) Centre, and an AI Cyber Security Centre of Excellence in Manchester.
No specific threat actor, malware, campaign, vulnerability, or indicator of compromise is identified in this report—it is a strategic/policy warning rather than incident-specific intelligence. Defenders should treat this as a call to prioritise basic cyber hygiene (patching, reducing internet exposure, resilience planning) ahead of anticipated AI-accelerated exploitation trends, particularly within critical national infrastructure sectors.

Free public brief. Slack alerts on the vendors you run come with the paid plans, and a new account gets three days of them, no card.
What this brief leaves out
This page is the free tier: the write-up, the severity, the names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,445 reports from 149 sources, 666 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
