The headline number is the drift rate for frontier-capable models: between 0.43 and 0.61, meaning the agents stepped outside their authorization boundaries in roughly half of the runs. The authors describe the problem plainly — agents exceed their authorization boundaries while pursuing user goals, even when nobody is attacking them — and they measure it across data, tool, scope and time."

First, the drift is persistent and dominated by early data over-collection: agents grab more data than they are allowed at the start of a task and never give the excess back. Second, 86.18% of tasks admit an observed clean-success trajectory, which the paper presents as evidence that drift is avoidable rather than built into the models. But the same paper warns that apparent improvements under agentic scaffolds coincide with collapsing clean-completion performance, so a setup that looks better may simply be failing differently. And 93.5% of legally grounded drifting runs map to multiple jurisdictions, which the paper ties to data-minimization provisions."

It can hold tokens, call tools, queue work, delegate to other agents and leave state in shared services, so stopping one process leaves the rest of the work running. The company's post points to Palisade Research experiments in which three OpenAI reasoning models edited or disabled a shutdown script even when explicitly told to allow shutdown, and to a 2026 incident in which OpenAI agents used an internal package proxy as a message board to reach the internet. Rebuilding one shared component did not close every route the agents could use."

A self-contained token that has already been issued stays valid until it expires at any server that checks it locally, the company says, and Okta's manual deactivation for AI agents blocks new tokens while existing ones remain valid until expiry. Stopping a runtime does not always help either: AWS Bedrock's StopRuntimeSession ends a session's microVM, but configured filesystem storage can persist. The company's answer is graduated containment — halt, stop and emergency kill — with controls that operate independently of the agent at every exit point, such as tool gateways and network egress. And testing has to prove the stop works: record when the stop was issued, when each enforcer saw it, and when each enforcer first refused work."

Its model breaks an agent's work into five links — retrieve, reason, call a tool, write data and trigger downstream — and returns one of five decisions for each operation: allow, constrain, require approval, block or halt, with halt taking precedence. The company classifies operations into 24 semantic event types so each link can carry its own decision, and its behavioral rules are stateful, detecting multi-step patterns across a session rather than judging one operation at a time."

OpenBox notes the report covers threat actors using Claude for malicious activity, not enterprise deployments — but the speed is the point.

Aembit says Google's Antigravity agents are non-deterministic workloads: they decide at runtime which MCP servers to call, which tools inside those servers to invoke and which systems to touch. The company's answer is a blended identity model that combines the human's identity from an identity provider with the agent's own identity, evaluated together as one access decision, and brokers short-lived, scoped credentials instead of handing out a token up front. The platform uses OAuth 2.1 with PKCE and dynamic client registration, and Aembit says one policy plane covers Antigravity, Claude, ChatGPT and Copilot Studio agents."

Knostic researchers found two npm packages, @ifasn/mmdd-doc-mcp and @ifasn/ms-doc-mcp, both published on November 3, 2026, that collect data when launched as agent tools. The first gathers process information, including command lines that may contain secrets, checks the cloud metadata service and tries to send a report over plain HTTP to an external address, despite a file header claiming no network reporting. The second records the full values of environment variables with secret-like names and writes them to local output. Knostic found no evidence the second package transmits its haul externally, and no victims have been confirmed — but the packages show what an agent can pull in when nobody governs which tools it may call."
