White Hats Seize Control of Stolen Bitcoin in Coldcard Vulnerability Rescue
A group of white hat hackers have successfully transferred Bitcoin they rescued from wallets exposed by a Coldcard vulnerability to a trust set up to return the funds to victims. The total amount transferred was 52.37 BTC, with approximately 40% of the associated Bitcoin from the second wave being swept by the white hats to protect the funds.
According to Alex Thorn, head of research at Galaxy Digital, 3.0134 BTC included in the transfer came from addresses that Galaxy had not previously tracked. Thorn stated that these funds were presumably also rescued from wallets affected by the Coldcard flaw, but could not confirm their origin.
Nick Bax, a security researcher and incident responder for SEAL 911, helped rescue about 50 Bitcoin at the end of July due to the imminent threat of theft caused by the Coldcard entropy flaw. The total number of BTC linked to the vulnerability is reportedly 1,830 across 9,162 addresses.
Those who may have been affected can enter their wallet addresses on the Crypto Recovery Trust website to determine if the trust controls their funds.
