The cryptocurrency world was shaken once again as the hacker behind the infamous $82 million Orbit Chain hack resurfaced after months of silence.
On June 8, 2024, the exploiter moved a staggering $47.7 million (valued at around $48 million at the time) to the notorious cryptocurrency privacy mixer, Tornado Cash.
The Orbit Chain hack, which occurred on December 31, 2023, was one of the largest cryptocurrency thefts of the year.
The cross-chain bridge, which facilitates the transfer of assets between different blockchain networks, was drained of $81.5 million across several transactions during the final hours of 2023.

Following the exploit, the stolen funds remained dormant for nearly five months, leading many to speculate that the hacker had abandoned their ill-gotten gains.
However, the recent transfer of $48 million to Tornado Cash has reignited interest in the case and raised questions about the hacker’s motives.
Interestingly, the total value of the stolen funds has increased significantly since the initial hack, now estimated to be around $121 million due to the appreciation of cryptocurrencies like Ether and DAI stablecoins.
The hacker’s decision to move a portion of the funds has puzzled experts, with some suggesting it could be a response to Orbit Chain’s recent revival of certain bridging services.
Orbit Chain, which has strong ties to the Klaytn ecosystem, has been tight-lipped about the details of the hack.
While they have stated that they are working closely with relevant authorities to track the stolen assets, the protocol has yet to provide a definitive explanation for the attack.
In a blog post, Orbit Chain hinted that the actions of their former chief information security officer might have played a role in the exploit.
“It has come as a great shock to our employees, and we are currently taking the necessary civil and criminal measures,” the protocol wrote, without offering further details.
The Orbit Chain hack is part of a broader trend of increasing cryptocurrency theft and exploits. According to recent data, hackers managed to steal over $540 million in digital assets during the first quarter of 2024, marking a 42% increase compared to the same period in 2023.
The Decentralized Finance (DeFi) industry, with its decentralized exchanges and over $100 billion in total value locked (TVL), has proven particularly vulnerable to these attacks.
As the investigation into the Orbit Chain hack continues, the cryptocurrency community remains on high alert, eager to uncover the truth behind this audacious heist and the motivations of the elusive hacker.
