ME News reported on Aug. 16 (UTC+8) that Bitcoin News monitoring, citing analysis from Galaxy Research (@glxyresearch), found identifiable behavioral fingerprints among attacker groups exploiting poorly secured COLDCARD seed setups. The ten largest clusters have moved an estimated 1,700 BTC in total, led by one group that transferred more than 1,080 BTC.
Researchers distinguished the groups by indicators including fee-setting tactics, transaction timing, consolidation patterns, and the final destinations of stolen coins. Several of the largest groups are believed to still control most of the misappropriated BTC.
