Yes, itโs real.
A new attack called EchoLeak just changed how we think about AI security.
No clicks. No downloads.
Just an email in your inbox.
And Copilot does the rest:
It scans it.
Follows hidden instructions.
And leaks your data silently.
This is the first zero-click attack on Microsoft 365 Copilot.

๐ง Copilot can read your chats, files, Teams, OneDrive
๐ต๏ธ A hacker email tricks it into sending that data out
๐ Traditional security? Useless here
๐งจ Even DLP can break Copilot's features
If you work in banking, healthcare, or defense โ this is your wake-up call.
๐ก Every AI agent in your business is now a potential leak.

๐ก๐ฒ๐ ๐ฅ๐๐น๐ฒ ๐ณ๐ผ๐ฟ ๐๐๐ฆ๐ข๐:
Trust, but verify.
And NEVER let AI read your inbox without real safeguards.
