Technical Description:

Trojan.Obfuscated.LA is a trojan downloader. It tries to download a file from 

hxxp://upd.host-domain-look.com/upd/check?version=0.1unk&fxp=9025<hex chars>

 

In order not to be detected by the firewall the program injects a part of it's code into a new process (iexplorer.exe) that it previously created. After the new malware is downloaded and put into execution Trojan.Obfuscated.LA exits.

 

Currently at the above URL address the program encounters an HTTP error (304 Not Modified).
