Based on the latest estimate, there are over 7,700 affected Bitcoin addresses. The previous reports included fewer compromised wallets and lower losses, suggesting that investigators are still finding more affected wallets as they continue to analyze the blockchain.

The updated statistics underscore the extent and significance of the theft, which continues to grow and impact the broader Bitcoin community.

The new data has been assembled by tracking the transaction on the blockchain and not from the open disclosures of the impacted users themselves. This research has continued on to track derogatory funding and search for addresses involved in the exploit.

COLDCARD has long been considered one of the top hardware wallets for Bitcoin users looking for the most control over their funds. But the recent event has sparked the debate about the security of self-custody devices again.

Unlike centralized exchange hacks, the attacks on hardware wallets can target individual users, especially if there are weaknesses in its firmware or wallet creation technology. Repeatedly, security experts have stated that continuing to keep firmware updated and adhere to recommendations from the manufacturer is still very important in reducing risk.

With several high-profile exchange failures in recent years, Bitcoin investors have increasingly turned towards self-custody which comes at a time when the auction is underway.

Self-custody gives counterparty risk away, but it also means that the security is up to the wallet owner and device manufacturer. The COLDCARD incident has once again made us aware that hardware, firmware, and operations security are essential to ensuring digital asset security.

With ongoing investigation of on-chain activity, users and wallet providers will likely experience even more pressure to improve security measures and mitigate possible risks for larger exploits in the future.
