If your phone was stolen or got lost somewhere, keep an eye out for any suspicious texts or emails: thieves and muggers could have a high-tech trick up their sleeves. A Brazilian woman who got robbed began receiving phishing attempts not long after the event. Her husband told Krebs on Security that he located the device using Find my iPhone and sent it text messages asking if he could buy it back. After that, he began receiving texts telling him that his iPhone had been found -- all he needed to do was click on a link to retrieve it.
