Someone is sending text messages to multiple employees at my company impersonating our CEO asking them to go buy gift cards. I know this is a common scam, but what I can't figure out is how they are linking the random phone number they are using to his name. This is not a phone number that has ever been associated with my boss in any way, but almost everyone getting the message on an iPhone is having his name appear as the sender. Somehow the scammers are associating the number they're using with his info in the recipients' phone. How are they doing this? His legit details show up as found with Siri. Is this some sort of vulnerability tricking siri? Edit: Couple of other notes. It is SMS not iMessage, so I don't think anyone has hacked his Apple ID/iCloud. Also, checked his contact info in his contacts and in our company GSuite directory.
