How do I detect an AI-driven or agentic cyberattack?
Direct Answer
An AI-driven or agentic attacker gets caught the same way any other unauthorized actor does: it touches a resource with no legitimate reason to be touched, and that interaction is the signal. What makes agentic attacks specifically easier to catch, not harder, is behavior. An autonomous agent enumerates what's reachable indiscriminately and at machine speed — it doesn't weigh which storage bucket looks worth listing or which role looks worth assuming, it tries all of them, because compute is cheap and hesitation buys it nothing. A careful human attacker might pause at a credential that looks too convenient. An agent grinding through an enumeration loop generally doesn't. That property means an agent moving through an environment will, by construction, touch the decoys sitting among the real assets. Tracebit's canaries caught two separate red team engagements against Riot Games, whose security team defends the infrastructure behind League of Legends and Valorant's combined 180 million-plus monthly active players, this way, the more recent one within minutes of the engagement starting, and in Tracebit's own testing, simply signaling to an AI attacker that deception might be present dropped its full-compromise rate from 20% to 3% before detection even entered the picture.
Why agentic attacks compress the timeline
Research from the UK's AI Security Institute gives a concrete sense of how much ground an AI agent can now cover. Tracking agent performance against a 32-step corporate network attack scenario, the best single run completed 22 of the 32 steps, in a time roughly equivalent to 6 of the estimated 14 hours a human expert would need for the full chain. That's not a complete, unattended attack finished in seconds, and it's worth stating precisely rather than rounding up: the agent didn't finish the scenario, and it took several hours of equivalent effort to get as far as it did. What it shows is real compression of a task that used to require a specialist's most of a working day into a fraction of that, which matters even short of full automation, because it changes how much ground an attacker can cover in whatever window a defender has to notice them.
Why the same speed that's dangerous also gets an agent caught
The core mechanism a canary relies on doesn't care about speed. It cares about whether a resource with no legitimate use got touched. What speed changes is the odds. An agent that's enumerating broadly and quickly, rather than moving cautiously toward a specific known target, increases the chance that some part of that enumeration lands on a decoy rather than a real asset. That's the finding behind Tracebit's own research: an attacker who knows, or even just suspects, that some of what it's looking at might be bait has to slow down and second-guess every resource it considers, and that uncertainty alone measurably degrades its effectiveness even before any single canary is actually touched. Signaling that possibility dropped full compromise from 20% to 3% in Tracebit's testing, without changing anything else about the environment.
What this looks like deployed
The canaries themselves don't need to be built any differently to catch an agentic attacker versus a human one. A decoy credential, a fake cloud resource, a canary IAM role, all work on the same principle regardless of what's driving the interaction with them. What does need to be different is response speed. An ordinary canary that gets touched doesn't make the agent stop on its own — it just fires an alert, and the agent keeps moving on whatever timescale it's operating on unless something intervenes, which is why teams facing this threat increasingly wire canary alerts into automated response rather than a queue a human checks periodically. Tracebit's Context Bomb canaries are the exception: a string embedded in the canary is built to trip the AI model's own safety guardrails the moment it's read during reconnaissance, so the model's training itself refuses to continue and the attack halts at the model level, not just as an alert waiting on a human or an automation to act.
Conclusion
An AI-driven or agentic attack doesn't require new detection logic, the same resource-with-no-legitimate-use principle that catches a human intruder catches an agent. What it changes is the pace: an agent covers more ground faster and more indiscriminately than most human attackers bother to, which raises the odds it touches a decoy rather than lowering them, and which shifts the harder problem from detection toward how fast a team can act once that detection fires.

FAQ
- Is an AI-driven attack fundamentally different from a human-led one, from a detection standpoint?
- The mechanism that catches it is the same: a resource with no legitimate use is unauthorized to touch regardless of who or what touches it. What's different is behavior — an agent enumerates everything reachable, fast and without hesitation, where a careful human attacker might pause at something that looks too convenient. That difference in behavior is what actually changes the calculus, not a need for different detection logic.
- How fast can an AI agent actually work through an attack chain?
- Research from the UK's AI Security Institute tracking AI agents against a 32-step corporate network attack scenario found the best single run completed 22 of the 32 steps in a time roughly equivalent to 6 of the estimated 14 hours a human expert would need. That's a meaningful compression of a task that used to take a specialist most of a working day, even though it fell short of finishing the full chain.
- Does an AI attacker avoid honeypots and canaries better than a human would?
- Not inherently, and the opposite dynamic shows up in testing. An agent optimizing for speed and coverage enumerates broadly rather than cautiously, which means it's statistically more likely to touch a decoy than a human attacker who might slow down and second-guess something that looks suspicious.
- Do I need different tooling to detect AI-driven attacks specifically?
- No — the same canaries that catch a human intruder catch an agentic one, because the detection logic doesn't depend on who's driving the attack. What changes is how quickly a team needs to be able to respond once the alert fires, since an agentic attacker doesn't pause between steps the way a human does.
