Coldcard thief prioritizes emptying third wave of vaults, has moved 97.09 BTC worth approximately $7.7 million

Odaily reported that, according to Bitcoin News monitoring, the Coldcard thief is prioritizing emptying the largest portion of the third wave of vaults. Galaxy Research stated that these wallets have transferred out 97.09 BTC, worth approximately $7.7 million, accounting for about 45% of the assets in this batch. The attacker created 293 2/2 vaults themselves and previously moved some tokens via THORChain on September 2, followed by multiple rounds of CoinJoin over the weekend. The vulnerability stems from a 2021 firmware flaw that reduced seed entropy to a minimum of 40 bits. Of the tokens stolen in this exploit, approximately 82% remain unmoved.
