In this episode, Nik welcomes back Alex Thorn of Galaxy Research on the Coldcard key generation vulnerability and the theft that followed. Alex explains how a March 17, 2021 firmware change left the devices silently defaulting to a much weaker random number generator, a bug that went unfound for five years, and why the victims are self-custody holders who never leaked a key or made a mistake. He walks through Galaxy's on-chain tracing across three confirmed waves totaling roughly 1,350 bitcoin, or about $88 million, why the stolen coins are sitting inert, how cheap compute and open source AI models made the exploit trivial, and what Coldcard owners should consider doing now.
