The Coldcard RNG failure was not due to a weakness in HW/SE RNGs.

The CC firmware’s multiple layers of complexity meant that the secure RNG was swapped for an insecure one. (They also never used SE RNG in Mk3)

I estimate that there is only <64 bits of entropy in these seeds

⚠️ I have strong reasons to believe Mk4/5 is also at risk, with those devices only having somewhat more entropy.

CHANGE YOUR SEEDS!!
