Analysis of malicious VBscript:


Yesterday, AntiVir detects a vbscript as :VBS/Dldr.Agent.sver

I try had a hand with that and try to find what it is actually doing:

Malicious script

Formatted script using malzilla

If you look at the script, it set the site name as nosensetoblock and temp folder location as tfolder. It loads a cmd file in temp location as follows:

 var genesis is equal to "%TEMP%\\keybtc.cmd", autorotatedomain="images";

 Use the Try catch method for auto reply (refer the image).

 Its good detect these kind of scripts :).
