Multichain Recovers Nearly 50 Percent of Stolen Funds
According to a report on February 18, Cross-chain router protocol Multichain announced the recovery of nearly 50 percent of stolen funds worth nearly $2.6 million in cryptocurrency after a month-long battle with an ongoing breach. The team also released a compensation plan to compensate users for their losses.
On January 10, blockchain security expert Dedaub warned Multichain of two vulnerabilities in its liquidity pool and router contracts, affecting eight cryptocurrencies, including Wrapped ETH (WETH), Wrapped BNB (WBNB), Polygon (MATIC) and Avalanche (AVAX).
A week later, on January 18, the Multichain team advised users to revoke the approval of the vulnerable smart contract to contain the damage immediately. However, this announcement encouraged more hackers to exploit the vulnerability, resulting in more than $3 million in losses.
According to Multichain, the liquidity pool’s vulnerability was addressed by upgrading the affected tokens’ liquidity to the new contract, adding:
“However, the risk remains for the users who have yet to revoke approvals for the affected router contracts. Importantly, users themselves have to be the ones to revoke the approvals.”
On February 18, Multichain reported that 4,861 of the 7,962 affected users had revoked approval and advised the remaining 3,101 addresses to take action as soon as possible. Of the stolen funds of 1,889.6612 WETH and 833.4191 AVAX, the team was able to recover 912.7984 WETH and 125 AVAX (worth nearly $2.55 million and $10,000 respectively).
