Back in 2014 I wrote a piece on how Avast! pulled personal information from wiped Android phones sold on eBay to demonstrate the dangers of selling off your old smart phone. Now it seems that trading in your iPhone with Apple has not been safe since 2015. The improvements in device encryption may severely limit the potential exposure of corporate email, texts and credentials from employee phones, but the steady escalation of data breaches and hacking attempts should make proper BYOD device disposal a requirement of you BYOD policy.
