Hacker stripped more than $50 million from Uranium crypto exchange, spent it on trading cards

U.S. prosecutors charged Jonathan Spalletta (aka “Cthulhon”/“Jspalletta”) for two 2021 hacks of the Uranium Finance cryptocurrency exchange: an initial exploit that drained roughly $1.4M (with a negotiated partial return) and a later exploit across 26 liquidity pools that extracted about $53.3M, prompting the platform to shut down. Authorities allege he laundered funds through a cryptocurrency mixer and spent proceeds on high‑value collectibles; he faces computer fraud and money laundering charges with potential decades of imprisonment.
