$100M Coldcard Hack Won’t Break Bitcoin’s Rally
Bitcoin’s price has shrugged off the largest hardware wallet exploit in crypto history, with the self-custody hack draining over $100 million from Coldcard devices since late July, yet markets have remained largely unmoved. The incident—which compromised an estimated 7,300 addresses across multiple attack waves and could ultimately total $130 million in losses—has exposed a critical...
Coldcard Exploit Drains $116M Bitcoin From 5,200 Wallets in Days
An attacker has systematically drained 1,816 Bitcoin worth approximately USD 116 million from over 5,200 Coldcard hardware wallet addresses since July 30, exploiting a five-year-old firmware vulnerability that crippled the device’s random number generation. The breach, which accelerated through multiple coordinated waves of theft, exposes a critical vulnerability in the self-custody narrative that has anchored...
Coldcard Hack Exposes $130M Bitcoin Theft as Market Watches
A five-year-old vulnerability in Coldcard hardware wallets has triggered three waves of coordinated attacks over the past week, with blockchain-monitoring firms now estimating total losses at more than $130 million in Bitcoin stolen from approximately 4,585 addresses. The exploit, which affected firmware version 4.0.1 released in March 2021, compromised the wallet seed generation process on...
Coldcard Breach Exposes $100M Bitcoin Theft, Fuels Custody Shift
Bitcoin and Ethereum markets are digesting one of the worst self-custody security failures in cryptocurrency history, as attackers exploited a five-year-old firmware vulnerability in Coldcard hardware wallets to steal over $100 million in Bitcoin across thousands of supposedly secure accounts. The exploit represents a watershed moment for the custody debate, potentially accelerating institutional adoption at...
Coldcard Hack: $116M Bitcoin Theft Tilts Custody Debate
Bitcoin hardware wallet users suffered nearly $116 million in losses after a critical flaw in Coldcard devices enabled hackers to drain over 5,200 addresses in coordinated waves since July 30. The breach, stemming from a 2021 firmware vulnerability that generated wallet seeds with insufficient entropy, has reignited a debate within the crypto industry about the...
$86M Coldcard Hack Reignites Self-Custody Security Debate
Approximately 1,367 Bitcoin worth $86 million to $89 million has been stolen from more than 4,500 Coldcard hardware wallet users following a firmware vulnerability discovered in devices manufactured by Canada-based Coinkite Inc. The breach, which unfolded in three distinct waves beginning July 30, 2026, has reignited debate over the security trade-offs inherent in self-custody while...
Coldcard Hack Exposes $70M Vulnerability in Hardware Wallets
A critical vulnerability in Coldcard hardware wallets has exposed a design flaw that allowed attackers to steal approximately 594 bitcoins—worth roughly $38 million at theft time, though later analysis suggests the total may exceed $70 million—from nearly 500 single-signature wallets in a 25-minute window on July 30. The breach, disclosed by Canadian hardware wallet manufacturer...
