An unknown actor compromised the Fogo Foundation and transferred 400M FOGO tokens to an attacker-controlled destination. Fogo has not disclosed the specific attack vector, affected Foundation wallet, or how authorization over the tokens was obtained. The Fogo blockchain itself was not initially compromised; the network was subsequently halted as a precaution to prevent movement of the affected tokens and upgrade the network to restrict associated addresses

The Fogo Foundation experienced a compromise by an unknown actor, resulting in 400 million FOGO tokens being sent to a bad actor. The Foundation immediately alerted exchanges, law enforcement, and forensic experts. Initially stated no impact on the blockchain, but later halted the mainnet as a precaution to restrict associated addresses and prevent further asset movement. Mainnet was later restarted after recovering and permanently removing 237 million tokens.
