Having concerns finding Superfish throughout your enterprise? With the Ziften App for Splunk, you can discover contaminated endpoints with an uncomplicated Splunk search. Simply browse your Ziften data and filter for the keyword “superfish”. The query is just:

The following image reveals the results you would see in your Ziften App for Splunk if systems were contaminated. In this specific circumstance, we discovered several systems infected with Superfish.
The above outcomes likewise refer to the binary “VirtualDiscovery.exe”. As it turns out, this is the core process responsible for the infections. Along with the Superfish root certificate and VirtualDiscovery.exe binary, this software likewise puts down the following to the system:
A computer registry entry in:
INI and log files in:
% SystemRoot% SysWOW64VisualDiscovery.ini.
% SystemRoot% SysWOW64VisualDiscoveryOff.ini.
% SystemRoot% System32VisualDiscoveryOff.ini.
% TEMP% VisualDiscoveryr.log.

dir cert: -r|where Subject -match “superfish”.
If the system is contaminated with Superfish, you will see results similar to the following image. If the system is tidy, you will see no outcomes.
Some researchers have actually mentioned that you can just eliminate Superfish by getting rid of the root certificate revealed above with a powershell command such as:.
dir cert: -r|where subject -match “superfish”|Remove-Item.
