Selling used Android phones poses huge identity theft risk, expert says



Android users who are looking to sell their old devices should be wary of the possible consequences. McAfee identity theft researcher Robert Siciliano warned that personal data from Android devices is not completely removed after a user activates the built-in wipe option, The Los Angeles Times reported on Friday. “What’s really scary is even if you follow protocol, the data is still there,” Siciliano said. If you have a BlackBerry or Apple device, Siciliano said your data can be fully deleted by following the manufacturer’s directions. As for smartphones running the Android operating system and computers running Windows XP, Siciliano recommends that people don’t bother with selling them at all. “Put it in the back of a closet, or put it in a vise and drill holes in the hard drive, or if you live in Texas take it out into a field and shoot it,” he said. “You don’t want to sell your identity for 50 bucks.” To test the security of various platforms, Siciliano purchased 30 smartphones and computers from Craigslist. The researcher was able to access personal data from 15 of the 30 devices through his own hacking efforts and the help of a forensic expert. The data obtained included bank account information, Social Security numbers, child support documents and credit card account log-ins.

I never think about this... very valuable information, at least for me.

It's right. Before selling used Android phones, we need to wipe all data on android phones without recovery in case of personal information leak.  Cause there are so many android data recovery program online to recover deleted data.

The biggest issue is that the phone has a "Hard Drive" so if someone really wants to steal your info they can use various different Hard drive recovery programs to try and retrieve erased data. There is always some data left behind.
