"The next wave of high-impact incidents will not look like traditional breaches. They will look like perfectly authorized activity producing catastrophic outcomes." [perfectly authorized activity]
This sentence directly names the structural shift: incidents will originate from agents acting within their permissions, not from attackers bypassing controls. This reframes the threat model from external compromise to internal authorization failure.
Reasoning from this article
The article supports this with concrete examples: agents making mistakes that cascade across systems, exposing data and breaking compliance before detection. The mechanism is the growing gap between instruction and intent—agents can reinterpret and chain actions dynamically, turning small ambiguities into systemic failures. This represents a fundamental change in how security organizations must model risk: the adversary is no longer external, but the authorized agent itself operating under incomplete or conflicting instructions.
