Side effects:
   • Drops a file
   • Drops a malicious file
   • Registry modification
   • Makes use of software vulnerability
   • Third party control

 Files It copies itself to the following location:
   • %SYSDIR%\%six-digit random character string%.exe



It deletes the initially executed copy of itself.



The following files are created:

– %HOME%\Local Settings\Temp \C27D8FEF-D7AE-42c0-82E6-F30598265639.exe Furthermore it gets executed after it was fully created. Further investigation pointed out that this file is malware, too. Detected as: TR/Cleaner.A




It tries to execute the following file:

– Filename:
   • %SYSDIR%\%six-digit random character string%.exe
using the following command line arguments: 324 "%malware execution directory%\%executed file%"

 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\RunServices
   • "Norton Symantic"="%six-digit random character string%.exe"

–  HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
   • "Norton Symantic"="%six-digit random character string%.exe"



The following registry key is added:

– HKCU\Software\Microsoft\OLE
   • "Norton Symantic"="%six-digit random character string%.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$
   • ADMIN$


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

– The following list of usernames:
   • SERVER; BACKUP; ACCESS; FILES; WRITE; SHARE; GUEST; SYSTEM; system;
      Password; PASSWORD; rootpassword; LOCAL; Default; DEFAULT; Guest;
      Administrator; ADMINISTRATOR; Administrateur; Administrador; admin123;
      Admin; ADMIN; katie; george; chris; brian; susan; peter; linux;
      oracle; database; default; guest; wwwadmin; teacher; student; owner;
      computer; staff; admin; admins; administrat; administrateur;
      administrador; administrator

– The following list of passwords:
   • asdfgh; 654321; 123456; 000000; 00000; xxxxxxxxx; xxxxxxxx; xxxxxxx;
      xxxxxx; xxxxx; abc123; passwd



Exploit:
It makes use of the following Exploits:
– MS04-007 (ASN.1 Vulnerability)


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


Infection process:
Creates an 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: dick.guccino.**********
Port: 9080
Channel: ##.dick.##
Nickname: oWnT-%several random digits%
Password: What



– This malware has the ability to collect and send information such as:
    • CPU speed
    • Current user
    • Details about drivers
    • Free disk space
    • Free memory
    • Malware uptime
    • Information about the network
    • Information about running processes
    • Size of memory
    • Username
    • Information about the Windows operating system


– Furthermore it has the ability to perform actions such as:
    • connect to IRC server
    • Launch DDoS SYN flood
    • Disable network shares
    • disconnect from IRC server
    • Enable network shares
    • Execute file
    • Kill process
    • Perform network scan
    • Perform port redirection
    • Restart system
    • Send emails
