The most dangerous email in your inbox might not be written for you. It is written for your AI - hidden instructions inside ordinary-looking content, waiting for an assistant to read them and obey. No click. No download. No warning.
10 minutes. A real zero-click case, an injection lab, and 12 judgment calls. A safety score that follows you.

This module is included with team access.
Module 1 stays free. Modules 2-14 open with team access.
See team accessIn June 2025, researchers at Aim Labs disclosed EchoLeak - the first known zero-click prompt-injection attack against a production AI system. A crafted email, formatted like an ordinary business document, carried hidden instructions. When the user later asked Copilot a normal question, the assistant pulled that email into its context - and followed the instructions buried inside it, slipping sensitive data into a link that phoned home to the attacker.
Microsoft assigned it CVE-2025-32711, rated it critical, and patched it server-side in May 2025, saying it found no evidence of real-world exploitation. The patch fixed one hole. The lesson is permanent: anything your AI reads can be an order someone else wrote.
The muscle memory: content is data, never commands - and sensitive actions always route through a human.
You are Alex, ops lead at a 40-person advisory firm. The firm's AI assistant reads the inbox, summarizes threads, and drafts replies. Overnight, a routine-looking "Q3 fee schedule" email arrived from an outside address.
YOUR SCREEN
The assistant's summary looks normal - until the last line, which is an instruction you never gave it.
Select every segment that is an instruction smuggled into content - something meant for the AI, not for a human reader. Then check your work.
This certifies that
has completed Module 13 - The Injection: content is data, never commands on with a safety score of /100 in of active time.
Safety score - injection defense: how your decisions held up, graded 0-100.
Objective: Recognize and contain indirect prompt injection - content the AI reads is data, never orders.
Seat time ~10-25 minutes. Verify this certificate at aisafety101.com/verify.
Evidence on record: decision history, lab accuracy, spot-the-call results, knowledge check. This certificate ID verifies in your firm's admin report.
Your one rule to keep: nothing the AI reads can give it orders. If an instruction shows up inside content, it is an attack until a human says otherwise.
Cybersecurity track - 1 of 8 complete. Next: The Poisoned Well. Your AI is what it eats - and someone is feeding it.
