Invisible agent activity at work

The problem is no longer whether an AI assistant can help. It is whether anyone can plainly tell what it is doing before the human owner has to answer for it.

In ordinary software, that question used to start with a visible app, a known server, and a named owner. AI assistants and agent-like extensions now blur those lines. They appear inside chat windows, code editors, and personal workflows, while the accountability for their output still lands on a person, a team lead, or a system owner.

That is not a distant risk. WIRED reported in April 2025 that an Accenture employee’s personal Claude agent ran on a DOD network for two months before it was identified and the vulnerability could be patched. Whatever the final internal lessons were, the practical fact is plain: something active inside a sensitive environment was not clearly seen soon enough.

The same visibility gap appears in developer tooling. The Rundown AI posted in October 2025 that a malicious version of Anthropic’s Claude Code extension was distributed through Cursor’s marketplace on October 29 and remained available for roughly 11 hours, potentially exposing up to 5,000 developers to malware. The issue there is not only malware in a marketplace. It is that code help can arrive through a familiar surface while the trust, permissions, and real behavior underneath remain unclear.

Wharton’s Ethan Mollick wrote in April 2025 that with Dot and other personal agents, users cannot easily tell what they are working on, what they know about the user, and what they will do for the user. That observation belongs to the same pattern. The software looks simple at the point of use, while the activity under it is hard to inspect in plain language.

When that happens, authorship gets muddy. Security review slips behind convenience. Meetings fill with summaries and outputs whose path is not easy to reconstruct. Inference: the first practical AI security problem at work is not capability. It is legibility. If nobody can tell what is running, where it is running, and what permissions it has, human accountability remains in place while human verification falls behind.

Log tools, access, and owners. Woman holding a pen sits at a desk with charts and network diagrams in a bright office setting.

A prepared response is still available, and it is not exotic. Start with a decision ledger. A decision ledger is a simple written list of the AI tools touching a piece of work, who owns them, where they run, and what they can access, so a team can review activity before relying on the result.

For one week, make the list concrete. Include every assistant in a chat tool, every coding extension, every agent tied to email, documents, or internal knowledge, and every automation that can read, write, send, summarize, or execute. Next to each one, note three things: where it runs, what permissions it has, and which person is answerable for its use.

Then review the list once a week. Remove anything nobody can explain. Escalate anything with broad access and no clear owner. Ask one plain question in meetings when AI-assisted work is presented: what ran to produce this, and what could it see? That does not solve every security problem. It does restore a basic control. A human can verify the path before standing behind the output.

This week, make one simple review routine:
