I cannot tell for sure. I didn't have time to really look at the Linux applications and what they do exactly. My guess is that most of the sensitive stuff is done on mp1 (reading the card, verifying the pin etc.) and the Linux just acts as untrusted relay to the network. Denial of service should be possible in the sense that it could just put the system in a boot loop.

> Denial of service should be possible

That's sounds like an overcomplicatedengineer solution.

The 10x engineer uses a hammer to deny service.

Aside: I'm an artist-engineer. I like the performance art of using an oversized hammer to solve a problem that isn't obviously solved using a hammer - and I love the discovery process when my aims fail.
