Dropped PE files

There are no dropped PE files.

HOSTS file anomalies

The Trojan modifies "%System%\drivers\etc\hosts" file which is used to translate DNS entries to IP addresses.
The modified file is 858 bytes in size. The following strings are added to the hosts file listed below:

61.129.115.198 www.xldd.com
61.129.115.198 www.ojiang.com
61.129.115.198 www.shuixian.net
61.129.115.198 www.xlarea.com


Rootkit activity

No anomalies have been detected.

Propagation

A worm can spread via removable drives. It writes its executable and creates "autorun.inf" scripts on all removable drives. The autorun script will execute the Trojan's file once a user opens a drive's folder in Windows Explorer.
