I downloaded Meta's Muse about four weeks ago.

I stopped using it three days later.

Before using Muse, I considered trying other AI agents, like OpenClaw and Hermes, but I didn't feel I had enough cybersecurity knowledge to be confident using open-source agents .

When Muse came out, I saw it was a simple app on the App Store.

I also felt good about the security since it was coming from a trillion-dollar company like Meta.

I decided to give it a shot.

I used it once.

Then a few days later, the agent sent me an unexpected message.
