Avast finds personal data on phones sold at pawn shops

Many people sell their used smartphones but fail to ensure their personal data is wiped away.

A year and half ago, Avast mobile security researchers bought 20 used phones from online consumer-to-consumer sites, like eBay and Amazon, in the USA. Using easily available recovery software, they were able to access more than 40,000 personal photos, emails, and text messages.
