What happened
Reports indicate a likely use of services from a major blockchain service provider by the attacker during the breach.
Why it matters
The recommendation to urgently move funds indicates a serious perceived security threat for bitcoin holders using popular cold storage hardware.
According to a report published by Bitcoin Magazine, experts have concluded that the thief who stole bitcoins from Coldcard devices likely utilized the services of one of the leading blockchain service providers. Based on this data, specialists recommend that owners of cryptocurrency stored on Coldcard devices immediately move their funds to another location.
The significance of the situation lies in the potential vulnerability of the infrastructure used to manage cold wallets, even if the device itself is physically secure. If the attacker indeed managed to bypass security through a third-party service, this jeopardizes the assets of all users relying on similar supply chains or software.
