Key Developments & Data
BitBox releases a firmware update patching two severe hardware wallet vulnerabilities.
Firmware version 9.26.5 fixes a memory corruption flaw in unconfigured BitBox02 and BitBox02 Nova devices.
A second vulnerability in the Silent Payments code allowed malicious hosts to lock Bitcoin $BTC to unintended addresses.
BitBox confirmed zero reports of active exploitation or lost user funds prior to the update.
The disclosure follows a separate flaw in Coldcard devices that led to over $112M swept from 8,600 addresses.
Self-custody keeps reminding everyone that eliminating middleman risk just shifts the entire attack surface to low-level microcontroller firmware.
