Coldcard hardware wallets suffered an exploit leading to 584 Bitcoin, or $38 million, being stolen. The attack exploited a fundamental flaw in its key generation process, draining funds from 500 wallets in just 25 minutes. For any crypto user relying on cold storage for security, this shakes the core promise of hardware wallets.
How We Got Here
The key generation flaw within Coldcard hardware wallets was present in their firmware for an unspecified period. This underlying vulnerability only became apparent when 500 wallets were simultaneously drained of 584 Bitcoin.
The Numbers
- The exploit specifically targeted the seed phrase generation within Coldcard's firmware.
- Approximately $38 million in Bitcoin was removed from 500 distinct Coldcard wallets.
- The entire attack sequence, from exploit trigger to fund transfers, concluded in under 25 minutes.
What Happens Next
🇮🇳 Why This Matters for India
For the 50 lakh active Indian crypto investors, especially those holding significant assets in cold storage, this Coldcard exploit serves as a stark reminder of hardware wallet risks.
The Take
This incident fundamentally erodes trust in the core security premise of hardware wallets, far beyond the $38 million in losses. Expect a significant migration of retail crypto users back to centralised exchange custody within the next six months.
