Seems like the classic drainer scam. You connect your wallet to the service, give it the needed permissions without checking what you are actually doing, and they drain your wallet of any valuable tokens. I have seen similar ads on Twitter about projects promising to return all the fees you spent on the Ethereum network. It's all a scam, of course, but obviously one that manages to trick enough people.
These types of scams are becoming more prevalent and it is concerning reading about how regular they are becoming. There is no way effective way to clamp down on them therefore people have to remain vigilant. Any sort of plugin people do not know too much about should not be downloaded especially one that will try to connect to a wallet. People should just a make a policy of not trusting them unless they are from a verified source with excellent ratings, reviews or feedback.
This scam project was widely promoted by numerous unscrupulous influencers. The ZKHAMSTER project exploited the wave of angry trends on Platform X against the ZkSync project due to their unfair airdrop. They aimed to deceive and drain users' funds through their rug project, which claimed to offer a refund for ZkSync users' fees using the scam $ZKHAMSTER token and their phishing website.
It is worth noting that any projects or sites claiming to offer a refund for cryptocurrency gas fees are a clear scam, as we have seen before with phishing sites claiming to refund Ethereum gas fees. Therefore, caution is advised, and it is essential not to follow the recommendations and tweets of influencers, as they are likely to be partners in this scam with the perpetrators of these fraudulent projects.
Maybe those are the star attractions that make gullible people fall for the scam in the first place. It is sad reading about any victim of wallet draining scams.
