Well I guess it just took 2 minutes to hack the Eu id app

Gotta watch those expensive numbskulls who blindly use AI lol :)

Hacking the #EU #AgeVerification app in under 2 minutes.

During setup, the app asks you to create a PIN.  After entry, the app encrypts it and saves it in the shared_prefs directory.

1.  It shouldn't be encrypted at all - that's a really poor design.
It's not cryptographically tied to the vault which contains the identity data.

So, an attacker can simply remove the PinEnc/PinIV values from the shared_prefs file and restart the app.

After choosing a different PIN, the app presents credentials created under the old profile and let's the attacker present them as valid.

Other issues:
1.  Rate limiting is an incrementing number in the same config file. Just reset it to 0 and keep trying.
2.  "UseBiometricAuth" is a boolean, also in the same file. Set it to false and it just skips that step.

Seriously @vonderleyen - this product will be the catalyst for an enormous breach at some point. It's just a matter of time.
