Cosmos Hub Rebooted After Neutron Governance Attack Unleashes Chaos

The Cosmos Hub network was restarted after a nearly 24-hour halt caused by an attack on Neutron's governance process. Validators resumed block production and normal operations at 12:00 UTC on September 23, according to the Cosmos Hub's official X account mirror.

The first post-restart block transferred 1,227,121 ATOM from a wallet linked to the attacker to a newly created address without a signature from the owner. The transfer was part of an effort to restore the chain's operations and respond to the incident, which affected assets associated with the alleged attacker.

The attack compromised 11 contracts connected to Astroport and Drop through an expedited Neutron governance proposal. Approximately $9.4 million in assets were exposed or drained as a result.
