Trezor, BitBox Warn of Fake Hardware Wallet Security Alerts

The shared newsletter provider is the more telling detail: a single vendor serving multiple Bitcoin firms turns one compromise into a sector-wide phishing surface, and hardware wallet makers are the ideal target because their users are conditioned to act on security warnings. This affects the customer lists of the affected companies rather than device security itself, so the practical risk sits in inboxes, not in the wallets. Whether this traces back to one provider or spreads to others using the same stack is the open question.
