Orbit Chain Exploiter Moves $47.7 Million to Tornado Cash After Five Months of Silence

Orbit Chain

After five months of “silence,” the exploiter responsible for the $82 million Orbit Chain hack on New Year’s Eve shifted $47.7 million to Tornado Cash, a cryptocurrency privacy mixer.

Details of the Recent Transactions

Blockchain analytics company Arkham Intelligence reports that seven transactions on June 8 transferred 12,932 Ether (ETH) totaling $47.7 million to a new address, which then sent the funds to cryptocurrency mixer Tornado Cash. Despite widespread claims that the exploit cost $82 million in losses, recent posts by Arkham suggest that the actual cost was likely closer to $100 million.

“They haven’t said anything since they took over $100 million in ETH and DAI from Orbit Chain five months ago,” stated Arkham, one of the first companies to notice the transfer, in a June 8 X post. According to Etherscan data, the majority of the $47.7 million in Ether transferred via Tornado Cash came in batches of 100 ETH. The hacker did not remove the $20 million in Dai (DAI) or any other currencies from the cross-chain bridge.

Impact of the Hack on Orbit and Community Response

The hack occurred on December 31, 2023, at approximately 8:52 p.m. UTC, in the last hours of 2023. The next day, Orbit Chain acknowledged the exploit and declared that it was “actively engaging” with foreign law authorities. On January 11, Orbit Chain’s X account stated, “Those who provide decisive intelligence that leads to identifying the attacker or recovering stolen assets will receive the bounty.” The company announced a maximum reward of $8 million USD for any information leading to the recovery of the stolen assets.

The total value locked peaked at $313 million in August 2022.
