A firmware bug quietly introduced into Coldcard hardware wallets in 2021 has let attackers drain an estimated 1,600 to 2,000 bitcoin, over $100 million, from cold storage addresses that sat untouched for years.
Galaxy Digital's Alex Thorn has been tracing the exploit in real time, and in this clip he breaks down exactly how the random number generator meant to secure private keys "failed silently" into "way too weak entropy," and lays out the wave-by-wave forensic trail he is using to track the attacker.
Alex Thorn identifies three confirmed attack waves and a possible fourth, and Chris Perkins makes the case that even a "trustless, permissionless" system still requires trusting something, in this case, a hardware wallet's own firmware.
