The researchers tested a range of second-hand Android devices running Android versions from Android 2.3 to Android 4.3 and found that in all cases they were able to recover account tokens – which are used to authenticate you once a password is entered the first time – from service providers such as Google, Facebook and WhatsApp. In a staggering 80 percent of cases, they were able to recover the master token.
Must admit ive sold phones before after doing a basic factory reset and not thought anything of it. There are probably thousands of 2nd hand phones for sale all over the country, wonder how many are at risk?
