Coldcard Hardware Wallet Hack Hits $100M in Stolen Bitcoin Across 3 Attack Waves — Here's What You Need to Know
4h ago · 1 source
Galaxy has confirmed that over $100 million in Bitcoin has been stolen through three distinct attack waves targeting Coldcard hardware wallets. The thefts represent one of the largest hardware wallet security breaches in crypto history, raising serious questions about the security assumptions many users place in cold storage devices.
WHY IT MATTERS
Think of a hardware wallet like a physical safe for your Bitcoin — it's a small device that stores your crypto keys offline, away from hackers on the internet. Coldcard was considered one of the most secure safes you could buy. This news is like finding out that a top-rated home safe brand had a hidden flaw that allowed burglars to crack it open — and they did it three separate times, stealing over $100 million total. If you own crypto and store it yourself (called 'self-custody'), this is a wake-up call that no single device is foolproof. Experts recommend using something called 'multisig,' which is like requiring two different keys from two different safes to open your vault — so even if one is compromised, your funds stay protected.
