BlackBerry Enterprise Servers vulnerable to TIFF Image based Exploit

BlackBerry Enterprise Servers vulnerable to TIFF Image based Exploit

If you are a BlackBerry Enterprise Network user, here is something you need to be careful about. BlackBerry Enterprise Server (BES) users have been warned that an image-based exploit could allow hackers to access and execute code on the servers used to support corporate users of BlackBerry smartphones.  The flaw that been rated as high severity and actual vulnerability in BlackBerry Enterprise Servers resulted from how the server processes image files. Scenario to Exploit Vulnerability :  A malicious person writes a special code and then embeds it in a TIFF image file. The person then convinces a Blackberry smart phone user (whose phone is connected to a corporate BES) to view the TIFF file. As soon as the image file loads on the phone, the code runs on the Blackberry Enterprise server and either opens up a back door in the network or causes the network to crash altogether as instructed in the basic code.

What if you could easily host malicious websites, send phishing emails, and manage compromised hosts across diverse internet addresses? This week's Cobalt Strike adds the ability to manage multiple attack servers at once.

Click a button to make that server active. It's a lot like using tabs to switch between pages in a web browser. To make use of multiple servers, designate a role for each one. Assign names to each server's button to easily remember its role. Dumbly connecting to multiple servers isn't very exciting. The fun comes when you seamlessly use Cobalt Strike features between servers. For example: Designate one server for phishing and another for reconnaissance. Go to the reconnaissance server, setup the system profiler website. Use the phishing tool to deliver the reconnaissance website through
