A firmware vulnerability in Coldcard hardware wallets compromised the random number generator used to derive private keys. Attackers reconstructed victims' private keys without accessing the devices. The estimated loss: $88.6 million in Bitcoin. Hardware wallets are marketed as the gold standard for cryptocurrency security. The assumption is that private keys never leave the device. This incident breaks that assumption at the firmware level. The RNG was the weak link, and it was compromised before the keys were ever generated. For security leaders evaluating hardware-based trust models: firmware integrity is the foundation. If you cannot verify that the cryptographic primitives inside a hardware security module are operating correctly, you are trusting the manufacturer's claim, not your own validation. cybersecuritynews.com/coldcard… #Cybersecurity
