Approximately 1,700 BTC Stolen by 10 Major COLDCARD Attack Groups, Largest Group Took Over 1,080 BTC

Odaily reported that, according to Bitcoin News monitoring, analysis by Galaxy Research (@glxyresearch) has identified distinct characteristics among various groups that exploited weakly secured COLDCARD seeds in their attacks. The 10 largest groups alone transferred approximately 1,700 BTC, with the biggest group moving over 1,080 BTC. Researchers differentiated the attackers based on patterns such as fee strategies, transaction timing, fund consolidation methods, and the destinations of the stolen BTC. Several of the largest groups are still suspected to hold nearly all of the stolen BTC.
