A new study has shown that one of the most common fixes to a stock smartphone ailment can be used to steal your data, and compromise your device. In the newly published paper, researchers from Israel's Ben-Gurion University of the Negev reveal how a replacement screen can easily be altered to override your mobile. By embedding a malicious integrated chip within a third-party touchscreen, the research team were able to manipulate the communications system on a Huawei Nexus 6P and LG G Pad 7.0. This essentially allowed them to record keyboard inputs, snap pictures of the user and forward them via email, install apps, and direct the user to phishing websites. A second class of attack also saw them exploit vulnerabilities in the handset's operating system kernel.
