The attacker sent a fabricated NEAR block that required a deposit of 5 ETH (over $7,850 at the time of writing). According to Shevchenko, the unknown expected Saturday morning that it would be difficult for the developers to respond to the attack.
6/15 Transaction successfully sent on Ethereum blockchain at block 15378741 Aug-20-2022 04:49:19 +UTC. Pay attention to the time of the attack: An attacker expected early Saturday morning that it would be complicated to react to the attack.

The system automatically rejected the fabrication block 31 seconds after the transaction was sent. As a result, the hacker lost his deposit, the user funds remained safe.
Shevchenko added that they are trying to carry out a similar attack on May 1. He suggested that the attacker participate in the NEAR network’s Layer 2 (L2) protocol bounty program rather than “suffer from stealing users’ funds and laundering them”.
14/15 And onward, dear attacker, it’s great to see the event from your side, but if you really want to do something good, instead of having a very hard time stealing users’ money and laundering it; you have an alternative – bug bounty: https://t.co/w67Y5AhRoH

The NEAR Protocol team launched the Aurora L2 protocol to interact with Ethereum in May 2021.
In May 2022, Aurora developers opened an approximately $90 million fund to accelerate the creation of DeFi applications. Later, the 1inch Network project announced the integration of the Ethereum platform with its virtual machine.
Recall that in August Matt Henderson, Product Manager of Aurora Labs, uncovered an “exciting and sophisticated” cryptocurrency scam scheme. OTC– a deal that he almost fell victim to.
