More than $80m in crypto stolen in Orbit Chain hack

The blockchain platform is working with numerous agencies including the Korean National Police Agency to support its investigation.

South Korea’s Orbit Chain, a platform designed to function as a multi-asset blockchain hub, has confirmed it suffered a major breach on the last day of 2023.

The company confirmed there was an “unidentified access to Orbit Bridge”, its decentralised cross-chain protocol, which resulted in more than $80m worth of cryptocurrency being stolen.

In a series of posts on X, Orbit Chain revealed details of the hack, saying the hacker used cryptocurrency mixer Tornado Cash to fund an initial Ethereum wallet before attacking Orbit Chain’s Ethereum vault. Tornado Cash hit headlines last year when its co-founders were charged with money laundering.

The stolen funds were then sent to numerous Ethereum wallets. Blockchain analytics platform Arkham Intelligence showed Orbit Chain’s Bridge balance plummet from $115m to $31m between 31 December and 1 January.

In a post on X yesterday (2 January), Orbit Chain said the stolen assets “remain unmoved” at the time of posting and the team is constantly monitoring the stolen assets.

Furthermore, we are also discussing close cooperation with domestic and foreign law enforcement agencies,” the company said in a post.

“We sincerely request that all members of the Orbit Chain community and the Web3 ecosystem help spread this information as widely as possible.”
