Infection Points

This Spyware arrives as a file downloaded from the following URLs:

• http://{BLOCKED}.ru/sloader/updates/own/file.exe

Installation

This Spyware drops copies of itself in the Windows system folder and appends garbage code to the dropped copy to avoid easy detection. The dropped copies uses the following file names:

• sdra64.exe

It creates the following folders with attributes set to System and Hidden to prevent users from discovering and removing its components:

• %System%\lowsec

(Note: %System% is the Windows system folder, which is usually C:\Windows\System on Windows 98 and ME, C:\WINNT\System32 on Windows NT and 2000, or C:\Windows\System32 on Windows XP and Server 2003.)

It drops the following files:

• %System%\lowsec\local.ds
• %System%\lowsec\user.ds

(Note: %System% is the Windows system folder, which is usually C:\Windows\System on Windows 98 and ME, C:\WINNT\System32 on Windows NT and 2000, or C:\Windows\System32 on Windows XP and Server 2003.)

It stays memory-resident by injecting codes into the following processes:

• SVCHOST.EXE
• WINLOGON.EXE

Autostart Technique

This Spyware modifies the following registry entries to ensure it automatic execution at every system startup:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows NT\CurrentVersion\Winlogon
Userinit = "%System%\userinit.exe, %System%\sdra64.exe,"

(Note: The default value data of the said registry entry is %System%\userinit.exe,.)

This Spyware adds the following registry keys:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows NT\CurrentVersion\Network
UID = "{Computer name}_{Random numbers}"

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\SharedAccess\Parameters\
FirewallPolicy\StandardProfile
EnableFirewall = "0"
