Hardware wallet attacks have been climbing the stack: seed phishing, then software supply chains, now physical implants and firmware exploits.
Each escalation increases the per-target cost to the attacker, and quorum architectures blunt every one of those classes simultaneously, because they all produce at most a single key.
There is no known remote attack that defeats a 2-of-3 with a separately gated cosigner.
