Less than two months ago, Duo Security released a DARPA-funded Android app called X-Ray, which looks for known privilege escalation vulnerabilities that could potentially give malicious apps access to root privileges on your device. Since launch, the company has already collected results from over 20,000 Android devices worldwide, and initial results show that over half of Android devices worldwide have unpatched vulnerabilities that could be exploited by a malicious app or hacker.

Sounds lovely. The hell with the “walled garden”, open rules.
