The Coldcard hack has now resulted in $130 million U.S. of stolen Bitcoin (CRYPTO: $BTC), according to market data and online updates.
Hackers have stolen an estimated $130 million U.S. in BTC from Coldcard hardware wallet users after exploiting a security flaw.
Nearly half ($70 million U.S.) of that Bitcoin was stolen in the first 41 minutes of the cyberattack. The situation has shone a light on cybersecurity when it comes to digital assets.
Analysts say it has also reinforced the benefits of exchange-traded funds (ETFs) that let people track the price of Bitcoin and other crypto without having to own it outright.
The Coldcard incident is the latest in a wave of crypto hacks this year. TRM Labs says there have been more than 200 hacks and nearly $950 million U.S. in losses this year.
Other crypto firms peg the first-half 2026 losses from hacks and cyberattacks at more than $1 billion U.S.
While it’s unclear who is behind the Coldcard attack, the hackers pulled off the theft by exploiting seed phrases, or keys, that act as a digital signature for the owners of the Bitcoin.
Coldcard was created by Toronto company Coinkite. It markets itself as “cold storage” for long-term Bitcoin users who want to keep their keys offline.
Security experts previously praised Coldcard as one of the most secure places to store BTC.
Victims of the Coldcard hack have flooded social media with pleas to return their stolen Bitcoin.
BTC was trading at $64,000 U.S. early on Aug. 5.
