Very often, scammers try to trick you into granting them a Token approval to get your ENS name. While it is not possible to recover names that have already been stolen (i.e. Owner transferred), you can explore your token approvals and revoke them to prevent further damage.
Resources for revoking permissions:
Explore the revoke.cash's FAQ (also, revokecash.eth.limo) to decide whether you need to revoke permissions that shouldn't be there.
Explore Etherscan.io's article on Token Approvals and decide whether to revoke permissions through their tool etherscan.io/tokenapprovalchecker
Note: Revoking permissions is not a solution if your wallet has been compromised and your seed phase exposed.
