Known Wi-Fi Vulnerability in BlackBerry 7; Here's How to Fix it - N4BB
Was looking for some news for those of us still on 7.1 and stumbled upon this.
Security Expert Raul Siles from Help Net Security has revealed a vulnerability in all major mobile operating systems, except BlackBerry 10. The vulnerability*exists in the method the devices use to detect and connect to Wi-Fi networks.
Siles says that every time the Wi-Fi of a device is turned on, the device starts checking through 802.11 probe requests for networks on a periodic basis. The probe requests search for networks on the device�s Preferred Network List (PNL), and once an appropriate response is obtained, it tries connecting to the network.
With the way the devices connect to a network, a skilled hacker could create a fake network thereby*capturing a device and manipulate it. The reason being due to the network discovery process is performed by sending out a generic probe request as an open broadcast with specific requests.
�This situation has been known since 2004; Microsoft fixed it for Windows XP in 2007 and recently in Windows Phone devices but it seems the other mobile device vendors are not as concerned,�*says Siles.
The issue does not appear to be prevalent in BlackBerry 10. However, users of BlackBerry 7.x*can resolve the issue by enabling the �SSID broadcasted� option from the advanced Wi-Fi settings of the device.
