 Files It copies itself to the following location:
   • %SYSDIR%\MStools1.exe



It deletes the initially executed copy of itself.

 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
   • "Microsoft Service TOols"="MStools1.exe"

–  HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
   • "Microsoft Service TOols"="MStools1.exe"

–  HKCU\Software\Microsoft\Windows\CurrentVersion\Run
   • "Microsoft Service TOols"="MStools1.exe"

–  HKCU\Software\Microsoft\Windows\CurrentVersion\RunServices
   • "Microsoft Service TOols"="MStools1.exe"



The following registry keys are added:

– HKLM\SOFTWARE\Microsoft\Ole
   • "Microsoft Service TOols"="MStools1.exe"

– HKLM\SYSTEM\CurrentControlSet\Control\Lsa
   • "Microsoft Service TOols"="MStools1.exe"

– HKCU\Software\Microsoft\OLE
   • "Microsoft Service TOols"="MStools1.exe"

– HKCU\SYSTEM\CurrentControlSet\Control\Lsa
   • "Microsoft Service TOols"="MStools1.exe"

 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$
   • ADMIN$


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

– A list of usernames and passwords:

– MS03-049 (Buffer Overrun in the Workstation Service)
– MS04-007 (ASN.1 Vulnerability)
– MS04-011 (LSASS Vulnerability)


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 or FTP 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 Server:

Server: po1.exceed-**********
Port: 6522
Server password: supersecret
Channel: #superbawts#
Nickname: [}{]%six-digit random character string%
Password: superbots
