Security Breach: Cross-Chain Bridge Exploit Costs Orbit Chain $81 Million

Orbit Chain finds itself grappling with a significant setback, losing a staggering $81 million in the aftermath of a sophisticated cross-chain bridge exploit. The platform, celebrated for its interoperability across various blockchains, made the security breach public on X. The assailant tactically employed Tornado Cash, a sanctioned privacy protocol, to finance a wallet before setting their sights on Orbit Chain's Ethereum (ETH) vault. Following this breach, the ill-gotten gains were dispersed among multiple Ethereum wallets, holding 26,741.6 ETH ($64 million) and approximately $18 million in the DAI stablecoin.

Despite the breach, Orbit Chain underscores that the compromised funds have not been moved. DeFiLlama data exposes a significant downturn in the total value locked (TVL) on Orbit Chain, plunging from $152 million to $71 million, with net outflows amounting to $81.88 million.

As of now, the stolen assets remain unmoved.
Our team is constantly monitoring the stolen asset, and we promise to inform the community once the address associated with the stolen asset has taken action.

The platform's native token, ORC, faced a harsh reality with a more than 13% decline post-exploit. However, it has since shown resilience, bouncing back to a $36 million market cap, according to CoinMarketCap.

This incident adds to the prevailing narrative of security challenges within the cryptocurrency sector. In 2023, users encountered losses nearing $2 billion due to scams, rug pulls, and hacks, as outlined in the annual report from the security app De.Fi. While a reduction from 2022, this figure underscores the persistent vulnerability of the industry to security risks.

Notably, Taylor Monahan, a developer at Metamask, draws intriguing parallels between the tactics observed in the Orbit attack and the modus operandi of the Lazarus Group. This North Korean hacking collective, responsible for siphoning off $3 billion through hacks and exploits over the past six years, as detailed by cybersecurity firm Recorded Future, raises concerns about the evolving sophistication of cyber threats in the crypto landscape.

Looks like 2024 is going to be another year of handing DPRK billions of dollars on a silver platter. ????
