The sage advice used to be \u201cdon\u2019t tell the world you are on vacation via your outgoing answering machine.\u201d Then we pretty much eliminated answering machines and the advice pertained to voicemail. As we got more technology, the same message was don\u2019t tell the world you are on vacation via your emails auto responder.\n\nFor a few years now I\u2019ve been warning people about how vulnerable they are when they post their whereabouts in social media. And it looks like the bad-guy figured it out and is taking advantage of peoples\u2019 naivet\u00e9.\n\nIn Nashua, NH, police busted a bunch of burglars they say used Facebook as a tool to gather intelligence on who is home and who is not home.\n\n\u201cPolice said they recovered between $100,000 and $200,000 worth of stolen property as a result of an investigation. Police said there were 50 home burglaries in the city in August. Investigators said the suspects used social networking sites such as Facebook to identify victims who posted online that they would not be home at a certain time.\n\n\u201cBe careful of what you post on these social networking sites,\u201d said Capt. Ron Dickerson. \u201cWe know for a fact that some of these players, some of these criminals, were looking on these sites and identifying their targets through these social networking sites.\u201d\n\nIt is obvious to me that none of these homes had home security systems, alarms or cameras. Due to the fact they were successfully burglarized. And once an intruder enters your home and does their dirty deed, your \u201ccastle\u201d and how you feel in it is never the same.\n\nProtecting yourself is real simple. Be cautious about what you post on social media and consider an investment in a home security system.\n\nRobert Siciliano personal security expert to Home Security Source discussing Social Media and giving out to much information on the CBS Early Show.
