Resumption of Operations by Interoperability Service Socket and Bridging Platform Bungee

The interoperability service Socket and its bridging platform Bungee recommenced operations early Wednesday following a suspected $3.3 million exploit which had led to a temporary halt in trading activities.

Details of the Apparent Exploit

The event unfolded as attackers targeted wallets with infinite approvals to Socket contracts, according to the developers. Approvals practice as permissions for blockchain-based instruments that grant applications the ability to access tokens, or a particular token, in a user's wallet. Security researcher @speekaway, who remains anonymous, was the first to highlight the exploits at approximately 18:20 UTC on Tuesday. A wallet associated with the exploit, believed to belong to the attackers, contains nearly $3 million in ether (ETH) and around $300,000 worth of other tokens.

Response to the Exploit

In response to the exploit, Socket halted operations to prevent the attack from spreading further. Early on Wednesday, Socket developers reported that the problem had been resolved and activities had been resumed. They further revealed that compensation plans were being devised.

Risks Associated with Cross-Chain Bridges

Cross-chain bridges like Bungee offered by Socket enable users to transfer tokens between different blockchains, however, they have been frequently exploited in the market. At the beginning of January, the new year's first crypto exploit resulted in an $81 million hack of Orbit Chain, a cross-chain bridge linking Ethereum$2,315 -2.42% to other networks. Attacks of this nature continue to be prevalent owing to the intricate nature of cross-chain tools, according to leading developers.

Advice for Bridge Users

Chainlink$15.6 -4.61% co-founder Sergey Nazarov noted in a message to the source that cross-chain security has multiple facets, which users should be cognizant of when opting for a bridge. He cautioned that like data oracles, there are numerous bridge variants that do not offer genuine security and do not elucidate their working beyond describing them as ‘decentralized' and ‘secure'. He advised users to question the security of their chosen bridge critically and to understand its position on the cross-chain security spectrum.
