BlackBerry PlayBook Jailbreak
Adrian Stone, the Director of the BlackBerry Security Incident Response Team at Research In Motion, this team is responsible for security issues and vulnerabilities that may impact RIM’s products, has made a post on the Inside BlackBerry Blog about jailbreaking.
In this post it becomes clear that since the 2.0 release there are no more jailbreaks possible on the BlackBerry Tablet Operating System.
So, what is a jailbreak on a PlayBook?
“Jailbreaking”, or gaining root access to a device, has become common place in both the mobile and gaming industries. Essentially, gaining this deeper level of access to the core functions of the device allows the user to do things not originally intended by a manufacturer, such as install software outside of “official” channels. Unfortunately, gaining this level of root access may increase the security risk. For this reason, most device manufacturers, including RIM, strongly discourage jailbreaking while understanding that whole communities exist for just that purpose. At RIM, we take these issues very seriously. Let’s walk through how we assess and respond to jailbreaking reports.
From a user perspective, there are two primary ways to jailbreak a device. First, there is the method where the user voluntarily makes changes that require: a) the device to be tethered to a computer; b) access to an authorized user account on the device; and c) may even require the user to make changes to the device’s default settings by putting it into developer mode (which can also compromise security). This method cannot be used by remote attackers to compromise user data or the integrity of the device as it requires both possession of the device and valid user credentials for the device. The second method involves less interaction on the user’s part. For example, a software bug may be exploited from a web page to gain root access to any mobile device and not require any interaction from the user except visiting the page.
We all know about the “DigleBerry” exploit and many have got this working, but I think it was not useful because there was not much possible.
Also this was not a real jailbreak in my opinion due to the fact that an USB connection was needed to do get root access and after gaining this access there was not much to do.
Seen some themes, heard of the android marketplace, but nothing really impressive stuff released or posted.
The developer of DingleBerry also states that his exploit no longer works, and RIM has worked and communicated on this exploit.
And in this post on the Inside BlackBerry Blog also comes with this statement that the manufacturer warranty will be void if jailbreak tools are used on the device:
To be clear, RIM recommends against installing any jailbreaking tool. Customers who use a jailbreaking tool on BlackBerry products void the manufacturer warranty and also increase the long-term risk of negatively impacting the stability and user experience of their BlackBerry products. Use of a jailbreaking tool could also amplify the impact and severity of a future security issue, making your personal data more vulnerable to theft and more difficult to protect. If new jailbreaks for BlackBerry products are reported, rest assured that we will evaluate them and take appropriate action to help protect customers.
