Now we heard that a serious security vulnerability was recently discovered that could wipe everything off of some Samsung phones. Although Samsung issued a patch for the Galaxy S III, it turns out it's not just Samsung devices that are affected. Here's how to find out if your Android device is vulnerable.
Essentially, some phones support special dial codes called USSDs (e.g., dialing *#06# to display the phone's IMEI number). Through malicious links in a website, SMS, NFC beam or QR code, hackers can perform a factory reset on your phone, lock the SIM card, and more—without warning.
