COLDCARD Mk3 Security Advisory. If you generated a seed on a Mk3 after firmware 4.0.1, your funds may be at risk. Mk4, Q and Mk5 are not affected based on our early analysis.Read the advisory and migrate carefully:

The attack is ongoing and may effect other versions as well. It is definitely impacting people as there are multiple tweets I have seen from people who lost funds.

Good that I never heard about this "Coldcard wallet" before,not that I own any BTC though😅!
And even if I did,I wouldn't use such kind of "wallet"!
Of course,this is very bad for people using it,I feel sorry for them!

I believe it's extremely important to stress that even users who IMPORTED or generated a seed with DICE are vulnerable, if they use the following features:
