Technical Description:

When started, the malware copies itself to the following location:
%windows%\[malware_name].exe

It creates the following registry entry:
HKCU\Microsoft\Windows\CurrentVersion\Run\"[malware_name]" = "%windows%\[malware_name].exe"

A few examples of [malware_name] are:
"msserv"
"msssecurity"


It synchronizes the current computer time by executing the following commands:
w32tm.exe /config /synffromflags:manual /manualpeerlist:time.windows.com,time.nist.gov
w32tm.exe /config /update

The malware adds itself as a Windows Firewall exception by executing the following command:
netsh firewall set allowedprogram %windows%\[malware_name].exe

The virus registers the compromised computer as a peer in its malware network and uses a randomly chosen UDP port to communicate with the other peers. It also sends to its network an unique ID for the compromised computer from the registry key:
HKLM\Microsoft\Windows\ITStorage\Finders\"config"

It drops a list of the initial peers to the configuration file:
%windows%\[malware_name].config
The malware updates this list by communicating with url-s like:
cadeaux-avenu[hide]/getbackup.php

The malware also has backdoor capabilities and can perform actions like:
- send spam emails by using its SMTP engine
- send system information from the compromised computer
- download and execute other malware
- update itself

It searches email addresses from files with the following extensions:
".wab"
".txt"
".msg"
".htm"
".shtm"
".stm"
".xml"
".dbx"
".mbx"
".mdx"
".eml"
".nch"
".mmf"
".ods"
".cfg"
".asp"
".php"
".pl"
".wsh"
".adb"
".tbb"
".sht"
".xls"
".oft"
".uin"
".cgi"
".mht"
".dhtm"
".jsp"
".dat"
".lst"

"@microsoft"
"rating@"
"f-secur"
"news"
"update"
"anyone@"
"bugs@"
