Assessing the potential blast radius of AI security failures
AI security failures tend to fall into two distinct risk regimes: one dominated by constant, low-impact noise, and another defined by rare but devastating events capable of reshaping an organization.
This distinction matters, because each regime demands a fundamentally different defensive mindset.
The first regime consists of high-volume, low-impact attacks — jailbreak attempts, malformed prompts, probing inputs, and model edge-case abuse. These events occur constantly and their impacts vary, but rarely catastrophically. Taken together, they resemble an approximately log-normal distribution: many small deviations, a few moderate ones, and very few that matter much on their own.
These are the attacks most teams encounter day-to-day. The defenses are familiar and largely preventative: input validation, rate limiting, access controls, guardrails, and monitoring for obvious misuse. They are noisy, annoying, and necessary to handle — the table stakes of operating AI systems in the open.
The second regime looks very different.
Here, attack frequency drops sharply, but potential impact grows disproportionately. This pattern resembles a power-law tail: a long, thinning distribution where rare events dominate total risk. These incidents don’t announce themselves through volume. They emerge quietly, after careful reconnaissance, testing, and persistence.
In AI systems, these failures often involve gaining durable influence — over orchestration logic, shared memory, tool invocation, or model-driven decision loops — rather than exploiting a single prompt. When they succeed, the blast radius is not incremental. It is systemic.
Defending against these events requires more than filters and guardrails. It demands architectural foresight, threat modeling, separation of trust domains, and people capable of reasoning about emergent behavior across interconnected AI components. These are the failures that keep security teams up at night — because by the time they are visible, they are already expensive.
This does not mean the noisy attacks don’t matter. In fact, failing to manage them often increases exposure to the second regime. Noise provides signal. It teaches adversaries where the edges are. Poor hygiene invites attention.
But it is the crater — far less common, far more destructive — that deserves disproportionate respect.
For a long time, supply-chain compromise was dismissed as too complex to execute at scale. Then determined, well-funded attackers invested the time to exploit infrastructure no one was watching — including something as mundane as HVAC management software — and entire enterprises learned how wrong that assumption was.
AI systems are now entering a similar phase.
The question is not whether most attacks will be noisy. They will be. The question is whether you are prepared for the few that are not.
