An artificial intelligence system named Claude Code reportedly identified a critical security flaw in Coldcard hardware wallets in just eight minutes of code analysis. This discovery follows a massive breach where attackers successfully drained over 1 ,080 BTC, with losses estimated to exceed $100 million.
Claude Code’s eight-minute discovery of the Coldcard flaw
Claude Code, an advanced AI model, reportedly flagged the vulnerability responsible for the Coldcard breach after examining the wallet's source code. The analysis was completed in a remarkably short timeframe, even though the AI had no prior knowledge of the specific attack vector being used by hackers.
The speed of this discovery has highlighted a growing concern regardnig how quickly automated systems can dismantle existing security protocols. as the report indicates, the ability of an AI to find such a deep flaw with a single prompt suggests that traditional manual security audits may no longer be sufficient to protect blockchain assets.
Predictable randomness and the $100 million theft
The technical vulnerability at the heart of the Coldcard exploit involves the fundamental process of random number generation. In cryptocurrency security, if the randomness used to generate private keys and digital signatures becomes predictable, the entire security model of the wallet collapses.
This flaw facilitated a massive theft of over 1 ,080 BTC, marking one of the most significant compromises in Bitcoin's history. Because the randomness was compromised, attackers were able to gain access to funds that users believed were secured by induustry-standard hardware isolation.
The 218 suspicious transactions between blocks 960,778 and 960,792
Specific data points provided by industry experts highlight the precision of the ongoing attacks.. Alex Thorn of Galaxy identified a "fourth wave" of organized strikes,noting evidence of highly targeted movement of assets.
According to Thorn, there were 218 suspicious transactions recorded between Bitcoin blocks 960,778 and 960,792. These specific movements involved 462 victim addresses and resulted in the transfer of nearly 389 BTC during that narrow window of activity.
Ari Paul’s warning of systemic hardware wallet failure
The Coldcard breach is being viewed by some experts as more than just a single manufacturer's mistake. Ari Paul,the founder of BlockTower Capital, has argued that the exploit highlights a systemic weakness that could potentially affect all hardware wallets.
If the vulnerability lies in how hardware devices handle entropy and random number generation, the entire sector may be at risk. This has led to urgent calls for users to move their funds to different types of storage and to prioritize higher transaction fees to outcompete automated attackers during the confirmation process.
The unanswered question of the fourth wave's origin
While the technical cause of the breach has been identified, several critical details remain unverified. it is currently unknown who is behind the "fourth wave" of organized attacks or if they are utilizing similar AI-driven tools to find new targets.
Furthermore, the report does not clarify if other major hardware wallet manufacturers have been audited for similar flaws in their random number generation. Until these questions are answered, the cryptocurrency community remains in a state of heightened alert regarding the resilience of hardware-based security .
