The Coldcard Disaster Gets Worse: The Hack May Have Reached $88.6M
That’s a massive increase from earlier estimates of the total losses of around $38 million, and it looks like the figure could be even higher as the attack continues. What’s very telling about this attack is that the person or people responsible seem to be maintaining a level of operational discipline. In all of the known transactions generated by the exploit, the attacker hasn’t spent any of the stolen coins.The coins have been accumulated in 4,585 addresses, which have been left unspent so far despite the high value of the deposits.
