Skype for Android contains serious vulnerability
Users of Skype for Android have been left vulnerable to a code exploit that allows a hacker to access a user's personal information. The proof of concept exploit uncovered by Android Police would allow a hacker to deploy a rogue app in the Android Market that, once downloaded, would allow access to a Skype user's full name, date of birth, city/state/country, home phone, office phone, cell phone, email addresses, bio and other details. The vulnerability appears to be the result of left over files that contain improper permissions, which allows anyone or any app to read them.
According to Android Police blogger Justin Case, Skype is currently investigating the issue after he brought it to their attention. In his view, Skype can address the issue by using proper file permissions, implement an encryption scheme, and put their apps through a more robust security review prior to release.
Users of Skype for Android can download the proof of concept app to test their Skype application to see what data the vulnerability yields.
