Research in Motion has issued an announcement advising Blackberry users to disable their Javascript after a critical vulnerability loophole has been discovered, that could allow hackers access to Blackberry devices. The security hole could allow hackers to remotely execute malicious code on Blackberry devices and even access confidential data stored on the phones.
The announcement has been released after Research in Motion smartphones were hacked during the yearly Pwn2Own competition. The hack affects devices running BlackBerry 6 OS and allowed a contestant to steal a complete contact list and cache of pictures stored on the Blackberry device, even allowing them to write a file to the Blackberry’s storage system.
Research in Motion explains:
“Users of BlackBerry Device Software version 6.0 and later can disable the use of JavaScript in the BlackBerry Browser to prevent exploitation of the vulnerability,” “The issue is not in JavaScript but the use of JavaScript is necessary to exploit the vulnerability.”
Understanding the Vulnerability
The vulnerability discovered in BlackBerry 6 OS is particularly concerning because it allows for remote code execution. This means that a hacker could potentially run any code they choose on the affected device without the user’s knowledge. This could lead to a variety of malicious activities, such as installing spyware, stealing personal information, or even taking control of the device entirely. The fact that this vulnerability was exploited during the Pwn2Own competition highlights the seriousness of the issue, as this event is known for attracting some of the world’s most skilled hackers.
The use of JavaScript in web browsers is a common practice, as it allows for dynamic content and interactive features on websites. However, in this case, JavaScript is being used as a vector to exploit the vulnerability in the BlackBerry OS. By disabling JavaScript, users can protect themselves from this specific attack, although it may impact their browsing experience.
Steps to Protect Your Device
To mitigate the risk posed by this vulnerability, BlackBerry users are advised to take the following steps:
1. Disable JavaScript in the BlackBerry Browser: This can be done by navigating to the browser settings and turning off the JavaScript option. While this may affect the functionality of some websites, it is a necessary step to protect your device from potential attacks.
2. Update Your Device Software: Ensure that your BlackBerry device is running the latest software version. Research in Motion frequently releases updates that include security patches and improvements. Keeping your device up to date is one of the best ways to protect against known vulnerabilities.
3. Be Cautious of Untrusted Sources: Avoid downloading apps or files from untrusted sources. Hackers often use malicious software disguised as legitimate apps to gain access to devices. Only download apps from official app stores and trusted developers.
4. Use Security Software: Consider installing security software on your BlackBerry device. There are several reputable security apps available that can provide an additional layer of protection against malware and other threats.
5. Regularly Back Up Your Data: In the event that your device is compromised, having a recent backup of your data can help you recover more quickly. Regularly back up your contacts, photos, and other important information to a secure location.
The discovery of this vulnerability serves as a reminder of the importance of mobile security. As smartphones become increasingly integral to our daily lives, the need to protect them from potential threats becomes ever more critical. By taking proactive steps to secure your device, you can help safeguard your personal information and maintain your privacy.
In conclusion, while the vulnerability in BlackBerry 6 OS is a serious issue, users can take steps to protect themselves by disabling JavaScript, keeping their software up to date, and being cautious of untrusted sources. By staying informed and vigilant, you can help ensure that your BlackBerry device remains secure.
