Decrypt reported on Aug. 11 that an attack exploiting a Coldcard firmware vulnerability caused about $130 million in losses. Following the hack, 233,000 Bitcoin moved from long-term holder wallets.
That was more than 100 times the value of the funds stolen from Coldcard. “While hackers were attacking Coldcard, roughly $15 billion worth of Bitcoin quietly moved in search of safer storage,” the outlet wrote. Some of the transfers came from Coldcard users shifting funds to multisig wallets. Others came from Ledger and Trezor users prompted to act by the breach.
