Not long after he arrived on the Stanford University campus in 2022 as a 17-year-old freshman, Theo Baker received a tip about the school’s president, the neuroscientist Marc Tessier-Lavigne. Baker, the son of two prominent Washington, D.C., journalists, had joined the staff of The Stanford Daily and was looking for a story he could dig into. And here it was: On a website called PubPeer, a forum for discussing scientific papers, critics were claiming that papers coming out of Tessier-Lavigne’s lab contained manipulated and fraudulent data. And that it had been going on for years.
THE HASHFLARE “CLOUD MINING” PONZI SCHEME (GLOBAL/ESTONIA)
Date: February 13, 2025 (Guilty Pleas) Perpetrators: Sergei Potapenko and Ivan Turogin
Case Description: This $577 million cryptocurrency fraud remains one of the largest digital asset scams in history, with major legal developments concluding in 2025. Potapenko and Turogin operated “Hashflare,” which they marketed as a massive cryptocurrency mining operation. Hundreds of thousands of victims worldwide purchased “mining contracts,” believing they were renting hash power to mine Bitcoin. In reality, the duo was running a sophisticated Ponzi scheme.
They created fake customer dashboards that showed “real-time” mining profits, but the money being paid out was simply the capital of newer investors. They laundered the proceeds through shell companies to purchase luxury real estate and a fleet of high-end vehicles. After a massive international investigation involving the FBI and Estonian authorities, the pair agreed to forfeit over $400 million in assets. This case underscores the “Cyber-enabled Fraud” warning issued by the FATF in early 2026: as technology evolves, the scale of fraud moves from local millions to global billions in the blink of an eye.
