The American Bar Association reports that scammers are fooling people into sending money by using fake Caller ID displays. Please understand that all devices can be manipulated to display false information about the identity of the person making the call or sending the email.
Martha Neil writes (excerpt):
Scammers may be “spoofing” phone numbers of attorneys—tricking caller ID into displaying whatever phone number the scammer wants it to display. According to the state bar, when unsuspecting clients answer the phone, they are then told they need to pay additional money to their attorney and are given a toll-free phone number to call. When they call that number, they are told how to send money to the scammer.
