Multichain Crosschain Router Protocol (formerly Anyswap) urges users to revoke approvals for six tokens to avoid loss due to a "critical vulnerability" that is currently being exploited by malicious individuals.
Users that have approved weth, peri, omt, wbnb, matic and avax on the multichannel platform are now at risk, experts warn. To avoid loss, the Multichain team advises users to cancel all of the approvals given to the specified tokens so that they can protect their crypto assets.
Multichain also published a step-by-step tutorial on how users can easily revoke approvals. In a tweet, the company also advised users not to transfer the affected tokens before revoking the approvals.
The vulnerability was first detected by a security firm called dedaub and was reported to the multichannel team. The issue was then solved, and multichain reports that all digital assets their v2 bridge and v3 router are secure.
However, at present, hackers still exploit the vulnerability to access user funds. At the time of writing, Multichain reports that a total of 445 WETH ($1,412,274.25) is affected.
Please revoke your approvals at your earliest opportunity. Somebody's exploiting this. https://t.co/fFGcrjNN0e

In the meantime, reports indicate that hackers and scams took more than $10.2 billion from users in 2021. However, despite the losses, the community takes appropriate measures to adapt. CEO and founder of security Immunefi, Mitchell Amador recently told Cointelegraph that “Despite the appearance of entirely new vulnerabilities in the on-chain economy, the community is adapting rapidly.” Amador says the community is sharing "best practices" to secure their digital assets.
Aside from immunefi, many digital asset security firms are on the lookout for possible hacks, scams, and carpet runs. Earlier this month, Certik identified Arbix Finance as a rug pull, warning users to stay away from the project to protect their digital assets.
