There is a easy way to prevent this type of attack. Just remove the sd-card after booting the device.

I wanted to find out how hard it is to manipulate the @SeedSigner
. It was easy as expected. Never give it out of hand! Simple swap to a manipulated sd-card and it logs your seed to it. Later the attacker can collect the sd-card and get your seed words.
Total lines added to the code are six.
Needless to say, it writes the seed also to sd-card if you scan your backup seed.

Wow I got ~1000 followers here on Nostr.
For now I just follow people that I think I know.
I followed too many on other social platforms. Which racked my feed.

The Mastodon instance http://bitcoinhackers.org got shut down. So I moved back to https://mastodon.social/@emzy "emzy@mastodon.social"
