The Trojan Notetaker
Why "Agentic AI" is the Latest Logic Fail in the History of Shadow IT
The Silent Guest in the War Room:
In my 30+ years of networking and cybersecurity, I’ve seen the same story play out under a dozen different names. In the 90s, it was unauthorized modems. In the 2000s, it was “Bring Your Own Device.” Today, it’s the AI Notetaker.
We spend millions on end-to-end encryption, multi-factor authentication, and Zero Trust architectures to keep our strategic conversations private. Then, we let a free AI bot named “Otter” or “Fireflies” join the Zoom call to “take notes.”
Nobody invited it. Nobody explicitly consented to it. But there it is—a silent guest vacuuming up your intellectual property and streaming it directly to a third-party cloud you don’t own, don’t control, and definitely haven’t vetted.
The 800-Account Facepalm:
In my three decades in the trenches, I’ve learned that convenience is the greatest enemy of security. A recent audit uncovered a single organization where employees had created 800 unapproved AI notetaker accounts in just 90 days.
This isn’t just a “minor compliance hiccup.” These bots are “agentic”—they don’t just sit there; they integrate with calendars, ride on top of authenticated user sessions, and spread like a digital plague. One employee grants a single permissive SSO sign-on, and suddenly the bot is “helpfully” crashing every meeting on their schedule, inviting other participants to sign up and keep the snowball rolling.
The Logic Fail is Three-Fold:
Data Sovereignty is Dead: Most free versions of these tools reserve the right to use your meeting audio to train their LLMs. Your confidential strategy is now part of a public algorithm’s “education.”
The Waiver of Privilege: For my colleagues in legal and government work, this is a nightmare. Allowing a third-party bot into a privileged conversation can be argued as a waiver of attorney-client privilege. Once that transcript is on a vendor’s server, it is subject to discovery.
The “Prompt Injection” Vector: We are now seeing “agent-to-agent” attacks where a malicious bot joins a meeting as a “guest” specifically to trigger prompt injections that exfiltrate data from other bots in the room.
The Architect’s Kitchen: A Recipe for Sanity:
In my kitchen, if a recipe calls for a delicate roux, you don’t just toss in whatever is in the pantry and hope for the best. Security is no different.
If you want to stop the “Trojan Notetaker” from raiding your pantry, move past the theater and implement actual controls:
Kill the “Auto-Join”: Mandate that no bot can join a meeting unless it is explicitly invited by the host.
Domain-Level Blocking: Use your admin center to block known bot domains (e.g.,
fireflies.ai) from joining your tenant meetings.The CAPTCHA Defense: Require a CAPTCHA for any “guest” joining via a browser—it stops most bots dead in their tracks.
Bottom Line
After 30+ years of building infrastructures, the most consistent lesson is this: If you wouldn’t let a stranger sit in your boardroom with a notebook, don’t let their bot do it.
