It cannot be said enough: hang up on callers whom you do not know, especially if they are trying to elicit any information from you. Better yet, if you don't recognize the phone number of the caller, don't pick up. Scam artists are less likely to try again if you're not answering.
Protect yourself and your employer by taking advantage of Caller ID service on your phone. Personally, if a call comes in to my cell phone from an unknown number, I let it go to voice mail.
It seems there is a new phone scam every day. Reported by Trustwave this week is a ruse that targets hotel and restaurant chains. This scam is perpetrated by a known cyber criminal gang that employs very convincing social engineering techniques like name-dropping and familiarity with other "insider" knowledge about your org chart.
When the caller reaches the hotel or restaurant's customer service line by phone, he/she claims to be a client who cannot log in to the reservations system. The caller may claim to know your boss or C-level executive.
