Three separate investigations of Android’s data deleting systems found it was possible to recover information in almost every instance.
Tesco’s Hudl tablet was singled out as a particularly egregious offender, having been found to contain a flaw that let attackers get at data saved to onboard memory. That’s because of a known bug in the Rockchip processor that powers the Hudl, reported IT Pro Portal.
The research was carried out on second-hand devices sold via auction sites such as eBay. Using a freely available software tool, penetration tester Ken Munro was able to easily read data from Hudl tablets to which the factory reset facility had been applied.
