The company at the centre of a Bitcoin hack has warned that artificial intelligence failed to detect the software flaw that was exploited to steal users\u2019 funds, now estimated at $130 million.<\/p>\n
Canada-based Coinkite, whose affected Coldcard wallets were drained late last week, said the vulnerability the hackers discovered \u201cis a warning for every company building Bitcoin hardware and software, not only us.\u201d Firms using AI to monitor security-critical code should undertake immediate reviews, Coinkite said in a blog post on its website.<\/p>\n
\u201cIf your team relies on AI review of security-critical code, we recommend you test it specifically against build and sub-module boundaries,\u201d Coinkite said. \u201cWe believe many Bitcoin projects, including those that rely on open-source code, require immediate review.\u201d<\/p>\n
The Coldcard hack has unnerved crypto investors because so-called \u201chard\u201d wallets, which use physical hardware to store private keys and are not connected to the internet, are considered one of the safest ways to secure digital tokens. The breach has put scrutiny on self-custody, one of crypto\u2019s founding principles.<\/p>\n
\u201cSelf-custody is a hallmark of digital assets, but Coldcard shows how one point of failure can shake trust in the whole model,\u201d said Nikhil Raghuveera, chief executive officer of Predicate, a blockchain compliance infrastructure provider. \u201cThe repercussions could be long-lasting because the ecosystem is built on the promise of being trustless. Over time the bigger risk is that investors move away from digital assets entirely.\u201d<\/p>\n

Following the hack, roughly 728 000 Bitcoin wallets moved funds in a single day, according Ki Young Ju, founder of CryptoQuant. The rush to move the tokens was significant enough to push down the \u201cmean coin age,\u201d a measure of the average number of days tokens have remained dormant, for the first time this year, he wrote in a post on X.<\/p>\n
\u201cThe excess likely reflects a move to safer storage,\u201d he wrote.<\/p>\n
Galaxy Research estimates that four suspected attack waves in the Coldcard hack have resulted in losses of about $130 million, according to its latest analysis.<\/p>\n
Coinkite said the bug appears to have lived in the part of the firmware where two separate software components interact, not in the parent code or cryptographic logic that are subject to most reviews.<\/p>\n
It\u2019s important for the broader ecosystem to understand how the bug arose and why it evaded detection, \u201cso they can avoid similar consequences,\u201d it said.<\/p>\n

\u201cWe\u2019ve run AI-assisted review against our critical codebases, including in the weeks before the exploit,\u201d Coinkite said. \u201cIt did not catch this vulnerability.\u201d<\/p>\n
Since the incident, Coinkite has tested its code against several frontier AI models, and \u201cnone of them caught it,\u201d the company said.<\/p>\n
\u201cIt\u2019s a reason for us, and anyone else relying on AI tools, to be specific about what they currently catch and what they might not.\u201d<\/p>\n
