My analytical colleagues from Block and Galaxy Research have presented important data that sheds light on one of the most high-profile thefts in the hardware wallet industry. This concerns the first wave of attacks on Coldcard devices, as a result of which the attackers withdrew 1,082.65 BTC. Apparently, the FBI managed to identify the organizers of this operation—and the key to the breakthrough was carelessness in using infrastructure for laundering funds.
The gist is that when moving the stolen assets, the hackers used an account with a paid blockchain data provider. This is not an anonymous service, but a commercial platform that keeps internal request logs. When the investigation matched these logs with the fund withdrawal transactions, the match was complete. In essence, the attackers left a digital trail themselves that led federal agents to them.
For me, this is a telling case that demonstrates a fundamental mistake many hackers make: they think that using paid tools guarantees anonymity, but in reality, such services are an ideal source of metadata for law enforcement. Every API request, every login log is a potential piece of evidence.
Why this matters for the market
First, this is a serious blow to Coldcard's reputation, which for a long time was considered a benchmark of security. Second, the FBI's success in this case is a signal to the entire crypto community: even the most well-thought-out fund withdrawal schemes can be exposed through the mundane logs of providers. I expect that after this news, pressure will increase on the KYC policies of paid blockchain services, and hackers will shift to more sophisticated mixing methods.
My verdict: this is not just a police operation, but a turning point in the fight against crypto crime. If the FBI actually detains the suspects, we will see a precedent that will change the approach to investigating such incidents—and force attackers to reconsider their operational risks. For investors, this is a reminder: the security of your assets depends not only on the hardware, but also on how you interact with external services.
