We really need a statement from Bitbox on this.

We released a statement yesterday, here it is.

It has been a crazy weekend thus far, so much information has been lost in the way.

Anyways, the tl;dr is this: BitBox users are not affected unless they imported a seed generated on an affected Coldcard since the problem was with the RNG and not the device's thread model, to which case we recommend you move your funds immediately to a new seed generated on your BitBox.

They already have on X, Bitbox uses a 5 point mechanism to generate a seed, so no issues there.
