No matter what mobile OS you have, they will all suffer from some issue at one time or another, and Windows Phone 7 is no different, as there is an SMS bug. This is a very serious problem, as attackers are able to disable messaging on these affected handsets. However, there is a simple fix, which we will get to a little later.
The way in which the attackers gain access to these phones is by simply sending an SMS to any WP user. You will know if you have been attacked, as your Windows Phone 7.5 will reboot and then you are unable to send any text messages. WinRumors has tested the problem on a number of models running different versions of Windows Phone, including Mango.
This bug will not just affect the SMS feature, as other areas will also come under attack in other ways, such as locking your device via live tile and Facebook, which WinRumors will elaborate more on. You can get around this issue, but only if you are fast when you boot your device up, as you have a limited amount of time to get past the lock screen.
As for the SMS bug, the only workaround for this is a hard reset of your handset — now that seems a little drastic. The likes of iOS and Android have also had SMS bugs, for the former attackers were able to gain total control over an iPhone, the issue with the latter was not as bad, as attacker could only manage to knock the phone offline.
Let’s not start panicking just yet, as we are told that the problem is not a security issue, just the way how Windows Phone handles SMS; we should expect some sort of update, but first we await a response from Microsoft.
