Patrick Steven Yarmoch, a supervising FBI special agent who worked in intelligence at the bureau's national headquarters, has been arrested after a federal filing accused him of stealing more than $1 million in cryptocurrency.

According to CoinDesk's report on the filing, Yarmoch allegedly told FBI colleagues that he pulled crypto keys from bureau systems and used them to move funds from accounts tied to foreign individuals he had investigated. The filing says he held a top secret clearance and worked in counterintelligence on a unit focused on an unnamed adversary nation.

The reported transfers were not described as a protocol exploit. Instead, the allegation is closer to an insider-access case: a law-enforcement employee with sensitive investigative access allegedly using that access to take digital assets. CoinDesk reported that the assets were handled through accounts involving Kraken, Suilend on Sui, and a Slush wallet.

Investigators also cited searches and records suggesting possible travel plans, including questions to AI tools about leaving the United States with about $1 million and becoming a resident or citizen of an EU country. Yarmoch was reportedly fired and arrested on July 31, then placed in detention in Alexandria, Virginia.

The case is still an accusation, not a conviction. But it is notable for crypto security teams because the alleged risk was not a smart contract bug or phishing kit. It was the custody of keys and investigative data inside a trusted institution.
