That makes sense. And even though every address’ activity is relatively transparent, one can infer that a BlockClock owner with a non-local setup (Start9, Umbrel, etc.), may be an owner of at least one ColdCard device (if they were a fan of the ecosystem)… and that device might be part of the subset of devices that generated insufficient entropy in their seeds.
With that foreknowledge in mind, that filters the set of vulnerable addresses significantly in the attackers favor. 🤦🏽♂️
