Episode Details

Coldcard Bitcoin wallets are under a fourth wave of attacks exploiting a firmware flaw dating back to March 2021—this time, attackers can override pending transactions by paying higher fees to steal funds before they’re confirmed. Unlike earlier waves that targeted specific addresses, this round uses fresh addresses per victim, bypassing multi-sig protections. If you used an affected Coldcard version before the fix, move your funds immediately to a new wallet and monitor unconfirmed transactions.
