Samson Mow Calls on Coldcard Users to Immediately Migrate Funds
Samson Mow warned in a post that users of any firmware version or MK of Coldcard should immediately migrate their funds.
The attack is ongoing, and action is needed quickly; temporarily use AquaBitcoin or Blockstream App until a new hardware wallet is obtained, and notify relevant parties as soon as possible.
The hardware wallet vulnerability incident in the Bitcoin security market has triggered a large-scale migration of funds from affected cold wallets to temporary software solutions or new hardware; trust in Coldcard is under pressure, while alternative wallets and secure migration services benefit, driving a repricing of self-custody risks.

As a Bitcoin advocate and CEO of JAN3, Samson Mow has long focused on hardware security and network risks. His call for a complete migration from Coldcard continues his vigilance regarding potential systemic vulnerabilities in self-custody, following previous public warnings about BIP and other hardware.
In terms of capital flow, users are forced to migrate assets from potentially compromised seeds to newly generated wallets, shifting resources from reliance on a single hardware to rapid alternative solutions; the motivation is to minimize losses while the attack window remains open, while adhering to self-custody principles.
Similar patterns can be seen in past large-scale migrations following hardware incidents like Ledger, as well as urgent transfers after software wallet private key leaks. Currently, Bitcoin self-custody is at a stage of "historical firmware risk concentration exposure."
The structural judgment belongs to technological substitution: when the entropy source defect of specific hardware is widely exploited, user trust shifts from "device is absolutely secure" to "flexible solutions that can be quickly migrated," leading to short-term demand premiums for temporary software wallets and new hardware in the supply chain.

Migration speed determines the scale of losses while attacks persist.
Any version may be implicated by historical vulnerabilities.
The ultimate insurance for self-custody is the ability to transfer quickly.
