Fogo halted its mainnet after detecting unauthorized activity linked to a compromised wallet, with an unknown attacker transferring 400 million FOGO tokens, according to the Fogo Foundation.
The foundation announced the incident on X early Aug. 29 and said it had alerted cryptocurrency exchanges. Law enforcement and forensic experts are also investigating the breach.
The foundation said the blockchain itself was not affected before the halt. The network was paused as the team worked to contain the incident and assess the extent of the compromise.
