Calls from scammers pretending to be from Apple and Amazon have been appearing lately. In the case of Apple, some of them mention suspicious iCloud activity.
In both scenarios, the scammers say you can conveniently press 1 to speak with someone (how nice of them!). Or they give you a phone number to call. Don’t do either. It’s a scam. They’re trying to steal your personal information, like your account password or your credit card number.
