Hackers have reportedly exploited Orbit Bridge, the bridging service of the cross-chain protocol Orbit Chain, for a total of $82 million, just three hours out before ringing in the new year.
In a Dec. 31 post to X (formerly Twitter), pseudonymous Twitter user Kgjr drew attention to the potential exploit, pointing to a series of large outflows from the Orbit Chain Bridge protocol. Onchain sleuth Officer CIA and blockchain security firm Cyvers have also posted similar information.

According to data from blockchain analytics platform Arkham Intelligence, the hackers appear to have made off with a total of $81.68 million in ill-gotten funds.
The purportedly stolen funds consist of $30 million in Tether (USDT), $10 million in USD coin, 9,500 Ether (ETH), 231 Wrapped Bitcoin (WBTC), and $10 million in the algorithmic stablecoin DAI (DAI), which have all been transferred to several fresh wallets.
This is a developing story, and further information will be added as it becomes available.
