How to detect Skyrecon software in IAG

  • 아티클

By default, IAG is capable of detecting a wide range of software on the client side. What happen if the software I want to check is not in the list ?

I had that constraint with one of my partners, Skyrecon

Here is the methodology we used :

1) asked the partner to create a VBS that will do the checks and will display at the end the result (wscript.echo “XXX”)

2) implement this script in IAG, replace the “Wscript.echo” by “RESULTS”

=> If you are not familiar about how to extend client-side analysis in IAG, check this post :click

Here is the script that we have implemented. WARNING : this script is not supported and is supplied AS IS :

Comments

As you can see at the end, we just put in remark the “wscript.echo” created by the developper of the script (skyrecon) and use the RESULTS function to send this variables/values back to IAG server.
