What are the security risks of smartphone disposal?

Hackers and cybercriminals are increasingly interested in gaining access to mobile devices because of the rapid growth of data they carry. What are the risks of data recovered from used smartphones or tablets? How do you avoid becoming vulnerable to data leaks from these obsolete devices? Google (Android) and Apple (iOS) have built in security options, like encryption and a factory reset, but is that secure enough? What is really necessary for secure smartphone disposal, and is it the same if you handle large disposal quantities?

In our report we look at the requirements for sanitisation of used mobile devices. Security means understanding the risks and limits of the data protection. In the report you will also find out more about flash storage in relation to data erasure, what is needed if the data stored on an iOS or Android device, if it is encrypted, and about the limits of certified erasure software for mobiles.

Data security on smartphones, in particular iPhones, became a hot topic in summer 2021 when it was revealed that Pegasus was able to transform them into complete spying tools. On our website you can find our full story about Pegasus and a report about built-in iOS security to protect data, focusing on the protection of encryption keys.
