Wi-Fi vulnerability found in iOS, Android, BlackBerry and Windows Mobile devices

Wi-Fi vulnerability found

Mobile phone security is a big concern these days when everyone has a smartphone that they have grown dependent on. According to Help Net Security, Security Expert Raul Siles has revealed an inherent weakness in smartphones that run on Android, iOS, BlackBerry and Windows Mobile operating systems. The weakness exists in the method these devices use to detect and connect to Wi-Fi networks.

According to Siles, 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. In simpler terms, instead of listening for signals, the devices shout out and hope for a network to shout back so that they can connect.

Because of how these devices connect to a network, a skilled hacker can create a fake network that can capture a device and manipulate it. This mainly happens because 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 problem was originally acknowledged on Android devices back when the operating system numbered at 2.x (Éclair, Frozen Yoghurt and Gingerbread) and 3.x (Honeycomb), but hasn’t been fixed as of yet, despite the OS reaching version 4.x (Ice Cream Sandwich and Jelly Bean). The vulnerability also exists in all versions of iOS, and BlacKBerry 7.x. Although, BlackBerry 7 users can resolve the issue by enabling the “SSID broadcasted” option from the advanced Wi-Fi settings of their devices.

“In some cases, there are options that can be changed to avoid this issue but on most devices when a Wi-Fi network is added manually it presents the vulnerable behavior and few users are aware of the security implications” Siles adds.






  1. saya benar” newbie, langkah pertama apa yang harus saya lakukan agar bisa membuat aplikasi berbasis android?

  2. I purchased an ACER A500 from China which is running around the Android Operating System. Regrettably, it’s all default applications which i have no need for, plus i can not download everything from the android market. Same with there anyway i’m able to set the program so its like i purchased it make up the U.S.?

    To explain, software differ slightly between regions, so there’s the U.S. form of the Android Operating System, along with a Chinese form of the Android U.S. My tablet automatically has got the Chinese form of the Android Operating System, since i have purchased from China, but i wish to U.S. form of the android O.S.

    Altering the nation with the configurations doesn’t work BTW. Its a massive problem since i have can’t read everything from china form of the android market.

  3. Personally, i prefer androids. Opinions?
