Federal prosecutors have indicted three individuals in connection with a multi-million dollar crypto theft scheme that relied on so-called “wrench attacks” — brazen physical threats used to force victims to hand over their digital wallets. The indictment, unsealed this week in California, marks the latest escalation of violent crime tied to cryptocurrency holdings.
The charges
Prosecutors allege the defendants targeted multiple victims across California, using intimidation and force to gain access to crypto accounts. The term “wrench attack” — drawn from a hypothetical scenario in crypto security circles where an attacker threatens someone with a wrench until they give up their private keys — has become a grim reality in cases like this one. The indictment does not specify the exact amount stolen, but sources describe the haul as multi-million dollar.
The three defendants face federal charges including conspiracy to commit wire fraud and kidnapping in aid of extortion. They are expected to appear in court in the coming days.
How it worked
According to court documents, the scheme involved surveilling victims — many of whom had public profiles as crypto investors or traders — then confronting them at home or on the street. In at least one instance, a victim was forced to transfer funds at gunpoint. The attackers then moved the stolen crypto through multiple wallets and exchanges to obscure the trail.
Prosecutors described the attacks as “brazen” and “calculated,” noting that the defendants allegedly researched their targets’ holdings before striking. The case was investigated by the FBI and the IRS Criminal Investigation division.
A growing problem
While crypto theft is often associated with hacks and phishing scams, physical coercion has become a persistent concern in the industry. The term “wrench attack” entered the vernacular after a 2018 BitcoinTalk post asked: “Given enough time and a 5mm wrench, can a motivated attacker get your private keys?” The question is no longer hypothetical.
California has seen a string of similar incidents this year, with local police departments issuing warnings to crypto holders about the risks of posting large holdings publicly. The indictment this week is one of the first federal cases to focus specifically on a coordinated, multi-victim wrench attack ring.
What happens next
The three defendants remain in custody pending a detention hearing scheduled for next week. Their attorneys have not yet filed any motions. If convicted on all counts, they face decades in prison. The case also raises unresolved questions about how crypto holders can better protect themselves from physical threats — and whether exchanges and wallet providers should offer more robust tools for emergency account freezes.
