Speaking to Russian newspaper Vedomosti.ru, Victor Chebyshev from Kaspesky Labs complained that fake Kaspersky apps have shown up in the Android and Windows Phone Store.
The app, claiming to be "Kaspersky Mobile”, cost around $4 and pretended to scan the handset on Windows Phone (on Android the app simply displayed random text on a picture of Kaspersky’s logo).
The apps contained no malicious code, and were only downloaded around 50 times, due to Kaspersky’s vigilance, but the issue is emblematic of the problem with Windows Phone Store has had with fake apps, indicating Microsoft’s supervision of the Windows Phone Store is providing increasingly less protection.
With apps now also a lot more powerful in Windows Phone 8.1, one can imagine a malicious app uploading private documents from your My Documents folder or infecting files on your OneDrive and synchronizing these infected files with your desktop.
A representative of Microsoft said that the company enables developers to quickly contact them and complaints are promptly considered and, if necessary, the application is removed.
