I haven't done much research on the company itself, but a Google search for "conduit toolbar" will show you just how many people search for this crapware, and how many people have created a "how-to" in order to uninstall the application. The company (Conduit) has a very plain page without offering much detail and appears to be affiliated with a company called Como, which helps businesses create smart phone apps. Whatever, I don't care. I just want the network indicators.
The main reason why I created this post was to, obviously, show you some network indicators for this toolbar. I had a hard time finding any kind of information about indicators for the toolbar; almost all of the sites that I found had information on how to uninstall the toolbar. What does the toolbar do? Well it is pretty malicious and transmits sensitive data to a remote server. File analysis shows that it will attempt to see if a virtual machine is running (anti-forensics), will steal private information from your web browser, fingerprint your system (BIOS, MachineGUID), and even modify your proxy settings. Yeah, this is a nice piece of software. On to the network indicators!
