Cronos Blocks have been restored. The company disclosed that after the lending agreement Tectonic was attacked, the validators paused the network earlier in the day to prevent further losses. The network resumed bloking at block 90,896,189 on Sunday at 23:49 UTC.
Validator pauses the network and rolls back the state.
Cronos stated that this chain stop was an emergency measure taken under validator consensus. After discovering that Tectonic had been attacked, the team first restored the on-chain state to its position before the attack occurred, and then resumed normal block production after the repair was completed.
This means that Cronos chose to cut off the attack path by suspending the entire network and rolling back the status. Such a approach is not common in public blockchains and is usually only adopted when real-time attacks are still ongoing and there is a risk of further funds being drained.
Approximately $6 million has been transferred across chains.
Security agencies PeckShield estimate that attackers transferred approximately $74 million from Tectonic, but before the suspension of Cronos, the actual amount transferred across chains to Ethereum was about $6 million.
According to this statement, there is still approximately $60 million remaining within the original ecosystem, and the attackers were unable to transfer it further. Cronos The official team did not disclose more detailed information about the composition of the assets in this update, but emphasized that the emergency measures have been effective.
- The attack involved an amount of approximately 74 million US dollars.
- Approximately $6 million has been transferred across chains to Ethereum.
- Network recovery time is 23:49 UTC
Crypto.com claims that platform services have not been affected
Crypto.com, co-founder, and Kris previously stated that the Cronos team is working together with the Crypto.com security team to investigate this incident. He also mentioned that Crypto.com and App ensured that the exchange services remained operational during the incident, safeguarding the funds of platform users.
Cronos It should be noted that its beta application is now being reopened to test users, and more features will be gradually restored thereafter. The team also stated that they will release a comprehensive review of this attack as soon as possible, explaining the causes of the vulnerability and the process of handling it.
Additional information:In this incident, Cronos adopted a network-wide emergency chain suspension, rather than just pausing a single protocol. Subsequent attention from the outside world will focus on the cause of the vulnerability in Tectonic, as well as the impact of this rollback decision on on-chain governance.
