Cosmos Hub Restarts After 24‑Hour Halt, 1.23 Million ATOM Shifted from Attacker Wallet

The Cosmos Hub experienced a prolonged outage, failing to produce blocks for 24 hours and 48 minutes before the network resumed normal operation.

Outage Details

During the downtime, the blockchain did not generate any new blocks, effectively pausing transaction processing across the network.

Attacker Activity

An attacker associated with the incident moved approximately 1.23 million ATOM from a wallet linked to the Neutron exploit.

Prior to the outage, the attacker purchased voting power using 20,199 USDC and staked that amount only 12 minutes before an expedited Neutron governance proposal closed.

Implications

• The halt highlights vulnerabilities in the Hub’s governance and staking mechanisms.
• Large‑scale ATOM movement may affect market sentiment and liquidity.
• Rapid acquisition of voting power suggests potential exploitation of fast‑track proposals.
