Cosmos Hub validators restarted the network at 12:00 UTC on September 23 after a roughly 24-hour, 48-minute halt, restoring block production and normal operations, according to the Cosmos Hub’s official X account mirror. The first post-restart block transferred 1,227,121.374688 ATOM from a wallet linked to the Neutron attacker to a newly created address without a transaction signed by the wallet owner, PrimeXBT reported. Cosmos Hub said its own network had not been exploited.
Validators restart Cosmos Hub after 24-hour, 48-minute halt
The restart ended an interruption that began in the wake of an attack involving Neutron’s governance process. The Hub’s update said validators had resumed producing blocks and that normal operations had returned.
The episode put Cosmos Hub validators at the centre of a response to an incident outside the Hub itself. The restart restored the chain’s operations, but the subsequent transfer made clear that the response also extended to assets associated with the alleged attacker.
First post-restart block transfers 1,227,121 ATOM
The first block produced after Cosmos Hub restarted included a transfer of 1,227,121.374688 ATOM—about 1.23 million ATOM—from a wallet linked to the Neutron attacker to an address created for the transfer.
PrimeXBT reported that the transaction did not include a signature from the wallet’s owner.
Neutron proposal compromised 11 Astroport and Drop-linked contracts
Approximately $9.4 million in assets were exposed or drained after an expedited Neutron governance proposal gave an attacker control over 11 contracts connected to Astroport and Drop, according to Unchained.
Cosmos Hub validators halted and later restarted the network during the response.
Cosmos Hub said it was not itself exploited and that the affected funds were limited to assets moved from Neutron. The incident was a Neutron-related governance attack rather than an exploit of Cosmos Hub itself.
