Mobile security researchers have identified an aspect of Android 4.0.4 (Ice Cream Sandwich) and earlier models that clickjacking rootkits could exploit. Researchers at NC State in the US have developed a proof-of-concept prototype rootkit that attacks the Android framework and could be used to steal personal information. The rootkit, which could be bundled with an app and is said to be undetectable by anti-virus packages, would allow an attacker to replace a smartphone’s browser with a version that logs key strokes to capture bank card data.
