The incident itself occurred on December 31, 2023, and the total damage from the hack amounted to more than $ 80 million. The South Korean company Ozys, which is behind the development of the cross-chain bridge, accused its former employee of facilitating the attack.
At the same time, Arkham recalculated the losses and concluded that the losses of the protocol exceeded $ 100 million.
"They stole over $100 million in ETH and DAI from the Orbit Chain five months ago and have remained silent ever since," the experts said.
The hacker's wallet still holds $66 million in ETH and more than $20 million in DAI and USDT stablecoins. The hacker also holds a small amount of wBTC, wETH, ORC and USDC.
After the attack, the Orbit team offered a maximum reward of $8 million for the return of funds or information about the hacker. However, this did not help in identifying the perpetrator.
According to DeFi Llama, the total value of funds blocked on the network is $37 million. Before the hack, the figure exceeded $150 million.
In January, Orbiter Finance announced plans to launch a second-tier Orbiter Rollup network based on zero-knowledge evidence.
Recall that in March, North Korean hackers used Tornado Cash to launder $147.5 million stolen from the HTX exchange in 2023.
In May, the person responsible for hacking the Poloniex cryptocurrency exchange transferred 100 ETH (about $308,000) to a mixer.
