Coldcard Vulnerability-Linked Funds Peak at $130 Million, White Hat Moves 52.37 Bitcoin to Crypto Recovery Trust

Odaily News: On September 21, a white hat actor transferred 40.71 BTC linked to the Coldcard vulnerability in a single transaction valued at approximately $3.31 million. The transaction consolidated funds from 11 addresses and included an OP_RETURN message pointing to the Crypto Recovery Trust.

Alex Thorn, head of Galaxy Research, disclosed that the broader consolidation involved a total of 52.37 BTC across multiple clusters of attacker addresses, accounting for approximately 2.8% of the funds tied to the vulnerability. A firmware flaw in Coldcard devices dating back to March 2021 resulted in insufficient mnemonic seed randomness, with the total funds involved peaking at approximately $130 million. (Decrypt)
