#BinanceWeb3Wallet #MaliciousCode

I'm new to crypto and my main intention is to get airdrop tokens a little by little from different projects completing required tasks.

Recently I participated a few airdrop events in Web3 and did everything as it needed to be done. Everything fine. But two days ago for a reason I was checking web3 wallet history and found total 3 transactions like in the image below. I don't know what are these and how did this happened, and what to do now.

Can anyone explain this whether I should be worried or need to do anything? Have you anyone ever faced this issue?
