A Bitcoin theft linked to a 2021 Coldcard hardware wallet firmware flaw has resulted in confirmed losses of about 714.8 Bitcoin, worth over $115 million as of August 16, 2023. The flaw allowed attackers to predict wallet seeds and steal private keys, with most thefts occurring between 2021 and 2022. Galaxy Research identified distinct transaction patterns and grouped victims into waves, tracing stolen coins back to the flawed firmware release date of March 17, 2021.
