 Files It copies itself to the following location:
   • %SYSDIR%\Monitor.exe



It deletes the initially executed copy of itself.



The following file is created:

– %WINDIR%\SoftWareProtector\monitor.pr

 Registry The following registry keys are continuously in an infinite loop added in order to run the processes after reboot.

–  HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
   • "Windows USB Hub Manager"="Monitor.exe"

–  HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
   • "Windows USB Hub Manager"="Monitor.exe"

–  HKCU\Software\Microsoft\Windows\CurrentVersion\Run
   • "Windows USB Hub Manager"="Monitor.exe"



The following registry keys are changed:

– HKLM\SOFTWARE\Microsoft\Ole
   Old value:
   • "EnableDCOM"=%user defined settings%
   New value:
   • "EnableDCOM"="N"

– HKLM\SYSTEM\CurrentControlSet\Control\Lsa
   Old value:
   • "restrictanonymous"=%user defined settings%
   New value:
   • "restrictanonymous"=dword:00000001

 Network Infection In order to ensure its propagation the malware attemps to connect to other machines as described below.

It drops copies of itself to the following network shares:
   • IPC$
   • C$
   • C$\windows\system32
   • c$\winnt\system32
   • ADMIN$\system32\
   • ADMIN$


It uses the following login information in order to gain access to the remote machine:

–Cached usernames and passwords.

– A list of usernames and passwords:

Exploit:
It makes use of the following Exploits:
– MS03-026 (Buffer Overrun in RPC Interface)
– MS03-039 (Buffer Overrun in RPCSS Service)
– MS04-007 (ASN.1 Vulnerability)
– MS04-011 (LSASS Vulnerability)
– MS05-039 (Vulnerability in Plug and Play)


IP address generation:
It creates random IP addresses while it keeps the first two octets from its own address. Afterwards it tries to establish a connection with the created addresses.


Infection process:
Creates a TFTP script on the compromised machine in order to download the malware to the remote location.


Remote execution:
–It attempts to schedule a remote execution of the malware, on the newly infected machine. Therefore it uses the NetScheduleJobAdd function.

 IRC To deliver system information and to provide remote control it connects to the following IRC Servers:

Server: voodoo.movie**********
Port: 4667
Server password: 420timeweedrocks
Channel: #Drug-Rulez
Nickname: Drug|Heads-%five-digit random character string%
Password: potrocks

Server: irc.splinters**********
Port: 4667
Server password: 420timeweedrocks
Channel: #Drug-Rulez
Nickname: Drug|Heads-%five-digit random character string%
Password: potrocks
