Hardware wallet maker Coldcard has released new firmware to address a seed-generation attack issue. The update includes version 5.6.1 for the Mk4 and Mk5, and version 1.5.1Q for the Q series.
In late July, Coldcard was hit by a hacking attack targeting a flaw in random-number generation. Estimated losses were 1,778 BTC, or $112 million.
