Jelly Bean App Encryption Breaks Thousands Of Apps In The Play Store - Google Disables DRM For Now

Piracy is a major issue for Android, and even more so for Android developers, which is why Jelly Bean introduced App Encryption. But this may be a case of the cure being worse than the disease: hundreds of developers of paid apps have chimed in on a Google Code thread, claiming that the encryption (or more accurately, the location of installed and encrypted apps from the Google Play Store) makes their apps entirely unusable, as account information and other stored data is removed after a device reboot.

Android Jelly Bean's Face Unlock "Liveness Check" Circumvented With Simple Photo Editing

If you're serious about security on your Android phone or tablet, you probably know that the Face Unlock feature introduced in Ice Cream Sandwich is a long way from secure. While Google didn't make any claims to the contrary, it looks like the extra "Liveness check" (which requires the user to blink after the initial scan) is almost as susceptible.

Security Researcher Demonstrates GPS Vulnerability That Could Let Hackers Track Users' Location, Take Over Phone

Over at Black Hat USA 2012, security researcher Ralf-Phillip Weinmann demonstrated a vulnerability in several Android devices that utilized A-GPS to send illicit messages to the device which could, he explained, be used to send a report of the device's location any time an A-GPS message was sent or even be used to gain complete control of the device.

In describing the attack, Weinmann pointed out that, for example, a malicious WiFi network could instruct a phone to relay all future A-GPS requests, even once the device has left the WiFi network's range.

Research Team Creates "Clickjack Rootkit" For Android That Can Hijack Apps, Exploit User Input

Xuxian Jiang, along with his research team at North Carolina State University, has cooked up a proof-of-concept "clickjack rootkit" which targets Android. The rootkit is unique not only in that it can function without a device restart, but also in that it targets Android's framework, not requiring deep modifications to the underlying firmware or kernel.

Clickjacking, for those unfamiliar, is a malicious technique typically used on the web to "trick" users into handing over control of their device or confidential information.

Taking advantage of that test period, security researchers Charlie Miller and Jon Oberheide have evidently found ways past Bouncer (which they will be presenting at the Summercon conference in New York this week).
