UK AI Institute: Autonomous Cyber AI Capability Doubles Every 4.7 Months
The UK AI Safety Institute reports that autonomous AI cyber capabilities may now be doubling every 4.7 months, much faster than before. This quick growth appears to make it harder for defenders to keep up, as attackers might improve faster than security teams can respond. Some models, like Claude Mythos, solved hard problems in more than half of tests, and AI agents are now able to complete starter-level cyber tasks about 50 percent of the time. Experts suggest that defenders may need to act in minutes instead of hours to match the speed of new AI threats. Analysts also note that current tests might underestimate the real dangers.
