This NCSC Assessment (NCSC-A) is a forward-looking strategic threat assessment rather than an incident report, examining how AI will shape cyber intrusion capability through to 2028. It presents three plausible scenarios - baseline, pessimistic, and optimistic - built around five drivers: geopolitical tensions, UK CNI cyber defence maturity, pace of AI development, availability of AI-cyber capability to threat actors, and workforce AI/cyber literacy. The assessment is explicitly probabilistic and not predictive, intended to inform proactive security strategy rather than describe current exploitation.
Key judgements include that by 2028 it is highly likely Russia, China and other nation states will routinely use AI-enabled cyber capability for geopolitical goals, increasing the scale and speed of sophisticated attacks against the UK. It is assessed almost certain that many systems will remain vulnerable to AI-cyber tools that identify and exploit weaknesses, lowering attackers' caution about losing access since replacement cost is minimal. The assessment judges it likely that attackers will target known vulnerabilities in CNI legacy technology and new attack surface created by AI deployment within CNI, and highly likely that AI-powered malware will be used in a ransomware attack against UK CNI before 2028. The pessimistic scenario raises the prospect of autonomous, self-replicating AI-driven cyber actors operating outside operator control, and wider criminal-market access to jailbroken AI models lowering the barrier for inexperienced actors.
For defenders, this is strategic foresight content with no specific IOCs, CVEs, malware samples, or named incidents - it is intended to guide long-term investment in patching cadence, legacy CNI system replacement, defensive AI tooling, and workforce AI-security literacy rather than immediate tactical response.

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.
