⚡️🚨 UPDATE - MK4s are vulenerable but are millions of times harder to steal from. MK3s can be stolen from a decent laptop, mk4,5s and Q would need much more compute.
The model:
- attacker has a roughly 2^20 UUID range that it knows cold cards fall in
- checks a 16 button press variancer in user behavior before generating the seed
You should still promptly remove funds from mk4,mk5 and Q.
