Usually, scams in the field of cryptocurrency only involve phishing so that hackers can get in, so most of the time we have to be cautious to avoid phishing link issues. Now, when it comes to extension wallets, we should still do your research first because we are also the poor ones in the end.
Find out about legitimate extension wallets, like Metamask and Phantom. So far, these two are okay, in my opinion, because I haven't seen any problems in the times I've used them.
