COLDCARD hacker identified by researchers through fixed-rate and other on-chain patterns

Odaily Planet Daily News According to Bitcoin News monitoring, Galaxy Research's Alex Thorn stated that researchers initially identified the first wave of COLDCARD theft incidents through a unique on-chain pattern: thousands of automated asset transfer transactions used the same fixed rate and exhibited identical transaction behavior. This characteristic enabled analysts to trace attacker activity through Bitcoin UTXO history and map out multiple rounds of coordinated theft.
