Only a few hours before the new year started, cybercriminals exploited Orbit Bridge, a bridging service of the cross-chain protocol Orbit Chain, resulting in the theft of about $82 million worth of cryptocurrencies. Orbit Chain officially confirmed the attack today (Monday) but did not furnish any details of the loss.
According to the official confirmation, the attackers exploited the protocol on “Dec-31-2023 08:52:47 PM +UTC.” The developers are now analyzing “the root cause of this issue” and “actively engaging with international law enforcement agencies.”

Orbit Chain was launched in South Korea in 2018 and enables cross-chain transfers between different decentralized protocols. The protocol has strong links to the Klaytn network, a modular layer-1 blockchain, and is used to transfer assets between EVM-compatible networks and Klaytn.

Arkham Intelligence, a blockchain analysis platform, pointed out that a total of $81.68 million in cryptocurrencies were siphoned from the protocol in five separate transactions. The largest transaction made by the attackers was $30 million in Tether, while the others are $10 million in USD Coin, 9,500 Ether worth over $21.6 million, 231 Wrapped Bitcoin (WBTC) worth about $9.8 million, and the rest $10 million in algorithmic stablecoin DAI. The cryptocurrencies were siphoned to fresh wallet addresses.
Attacks on crypto platforms are common. Despite the constant efforts of the developers, hackers find ways to exploit the crypto platforms. According to a recent report, crypto users lost nearly $2 billion to scams, rug pulls, and hacks in 2023. Notably, this figure becomes even more substantial when factoring in the $40 billion lost…
