Approximately $30 million stolen in the first 10 minutes, Coldcard vulnerability attacker prioritized highest-value wallets first

Odaily News, according to Bitcoin News monitoring, Chainalysis analysis of the Coldcard exploit involving over $38 million shows that the attacker deliberately targeted the highest-value wallets first, including one holding $1.8 million, indicating that victims had already been profiled before asset transfers began. Approximately $30 million was stolen in the initial 10 minutes, followed by around 500 wallets being drained within 25 minutes. Block's Clay Garrett stated that investigators also confirmed the attacker used a paid account with a well-known blockchain service provider to query victim addresses during the operation. The provider's internal logs match the request timestamps and sequence, but Block stated that no evidence was found suggesting the company knowingly assisted in the theft. Relevant information has been shared with authorities.
