Via a Tweet from Ry we have still more info on the security issues with Android (emphasis in the original):
The Bluebox Security research team – Bluebox Labs – recently discovered a vulnerability in Android’s security model that allows a hacker to modify APK code without breaking an application’s cryptographic signature, to turn any legitimate application into a malicious Trojan, completely unnoticed by the app store, the phone, or the end user. The implications are huge! This vulnerability, around at least since the release of Android 1.6 (codename: “Donut” ), could affect any Android phone released in the last 4 years1 – or nearly 900 million devices2– and depending on the type of application, a hacker can exploit the vulnerability for anything from data theft to creation of a mobile botnet.
While the risk to the individual and the enterprise is great (a malicious app can access individual data, or gain entry into an enterprise), this risk is compounded when you consider applications developed by the device manufacturers (e.g. HTC, Samsung, Motorola, LG) or third-parties that work in cooperation with the device manufacturer (e.g. Cisco with AnyConnect VPN) – that are granted special elevated privileges within Android – specifically System UID access.
Installation of a Trojan application from the device manufacturer can grant the application full access to Android system and all applications (and their data) currently installed. The application then not only has the ability to read arbitrary application data on the device (email, SMS messages, documents, etc.), retrieve all stored account & service passwords, it can essentially take over the normal functioning of the phone and control any function thereof (make arbitrary phone calls, send arbitrary SMS messages, turn on the camera, and record calls). Finally, and most unsettling, is the potential for a hacker to take advantage of the always-on, always-connected, and always-moving (therefore hard-to-detect) nature of these “zombie” mobile devices to create a botnet.
I’ve known there were lots of security issues with Android but this is much bigger than I imagined. If you were concerned about various three letter agencies sucking up data about you (or even your snail mail) then you should be even more concerned that just about anyone that is technologically competent can take complete control of your Android phone.
A little over two years ago I purchased a Android phone with thought of developing apps for it. I never got around to it and after releasing Field Ballistics for Windows Phone I gave it further consideration. I decided not do pursue Android as an alternate platform. I’m glad I made that decision. Would you want everyone and their brother looking at the map on your phone showing your location and the location of your next target? At Boomershoot that would be an invitation to have “your” target poached.
