Coldcard hacker moves $7.7 million in BTC, 45% of bitcoin stolen in third attack wave

The Coldcard hacker moved about $7.7 million in BTC, roughly 45% of the bitcoin stolen in a third wave of attacks tied to compromised Coldcard devices. On-chain consolidation of those funds increases the likelihood of laundering or attempts to cash out, raising near-term risk of sell pressure and traceability efforts by exchanges and investigators. The pattern underscores persistent supply‑chain and physical security vulnerabilities for hardware wallets and will drive tighter provenance checks and intensified monitoring across the Bitcoin ecosystem.
