The peak amount of funds involved in the Coldcard vulnerability reached 130 million USD, with white hats transferring 52.37 bitcoins to Crypto Recovery Trust

White hat actors transferred 40.71 bitcoins related to the Coldcard vulnerability into a single transaction, valued at approximately 3.31 million dollars. This transaction aggregated funds from 11 addresses and included OP_RETURN information pointing to the Crypto Recovery Trust.

Alex Thorn, head of Galaxy Research, revealed that a larger aggregation transferred a total of 52.37 bitcoins, involving multiple clusters of attacker addresses, accounting for about 2.8% of the funds involved in the vulnerability. A firmware flaw in Coldcard devices from March 2021 led to insufficient randomness in the mnemonic phrases, with the peak amount of funds involved being approximately 130 million dollars.
