Threat Model
In security engineering, the process of systematically identifying potential attackers, attack paths and asset vulnerabilities. It has traditionally centered on malicious actors; autonomous AI agents introduce a new subject: automated tools that have no malicious intent but may cause substantial harm.

At runtime, REVA injects three types of precomputed information into the LLM: a precomputed threat model for the module in question, lightweight static analysis findings, and call graph information.
Traditional threat models often layer attackers by capability, such as script kiddies, organized crime, and nation-state APTs, and design controls of differing strength for each layer.
The core of reassessing the threat model is not simply adding an 'AI attacker' line, but re-judging the capability boundaries of attackers at each layer and checking whether existing controls can still cover the raised lower bound.
If an Agent acts on credentials or permissions from memory with full confidence, an attacker does not need to directly compromise the system; they only need to block or delay the propagation of updates to indirectly control the Agent's behavior.
The paper's threat model assumes the attacker possesses the exact same vision-language encoder and knows the geometric layout of the page.
The distortion bounds derived in this study apply to an omniscient attacker: one who can observe the entire parameter trajectory, knows all training samples except the target record, and has access to the overall distribution of the training data.
In its statement, OpenAI used the phrase 'attacking real-world targets,' framing the AI agents' runaway behavior as active attacks rather than passive failures.
