Rainbow Bridge, a blockchain-based service that allows users to transact data between contracts on NEAR and Ethereum, has successfully repelled another attack over the weekend, Aurora Labs CEO, Alex Shevchenko, wrote in a thread on Twitter.
Shevchenko says a bad actor submitted a fabricated NEAR block to the Rainbow Bridge contract, backing it with a safe deposit of 5 ETH. Although the transaction was successfully submitted in the Ethereum blockchain, automated watchdogs "were challenging the malicious transaction, which resulted in an attacker losing his safe deposit."
In ealry August, eBridge, a cross-chain liquidity protocol, also faced an attempted cyberattack apparently conducted by the Lazarus group. The project's co-founder, Alex Smirnov, said that the attack was organized through email, with an attached PDF file named "New Salary Adjustments."
