Coldcard Security Bug Triggers Massive Bitcoin Movement

A serious security flaw in Coldcard hardware wallets has sent shockwaves through the Bitcoin market. Coinkite recently warned that certain firmware versions failed to generate sufficiently random seed phrases, leaving thousands of wallets vulnerable to theft. Analysts estimate that attackers have already drained over 1,300 Bitcoin, worth roughly 89 million dollars, across multiple waves of attacks.

In response to the news, Bitcoin holders began moving their assets in record numbers to prevent potential losses. Data shows that daily active addresses surged to nearly one million, a level not seen since late 2024. Market observers noted that this activity was driven by users migrating funds to new, secure wallets rather than signs of a general sell off. The sudden rush of transactions has temporarily distorted typical market signals and on chain metrics.

This incident has complicated recovery efforts, as investigators report that common AI security tools are blocking their attempts to track stolen funds. Safety guardrails on major American AI models reportedly flagged forensic data as malicious, preventing investigators from using them to trace the attackers. This forced teams to look for alternative, less restricted tools to help identify and contain the threat.

For now, the priority remains protecting remaining assets. If you hold a Coldcard device, it is critical to verify if your firmware is affected and move your funds to a new, secure wallet immediately. Analysts suggest watching for continued, unusual movement of older coins as users finalize their security migrations.
