Arrival Details

This Trojan Spy arrives on a system as a file dropped by other malware or as a file downloaded unknowingly by users when visiting malicious sites.

Installation

This Trojan Spy drops the following copies of itself into the affected system:

• If sample executed without administrative privileges:
  • %AppDataLocal%\{string1}{string2}\{string1}{string2}.exe
• If sample executed with administrative privileges:
  • %System%\{string1}{string2}.exe

(Note: %AppDataLocal% is the Local Application Data folder, which is usually C:\Documents and Settings\{user name}\Local Settings\Application Data on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\Users\{user name}\AppData\Local on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit).. %System% is the Windows system folder, where it usually is C:\Windows\System32 on all Windows operating system versions.)

It adds the following processes:

• {malware file path}\{malware file name}.exe --{8-random characters}
• If sample executed without administrative privileges:
  • %AppDataLocal%\{string1}{string2}\{string1}{string2}.exe
  • %AppDataLocal%\{string1}{string2}\{string1}{string2}.exe --{8-random characters}
• If sample executed with administrative privileges:
  • %System%\{string1}{string2}.exe
  • %System%\{string1}{string2}.exe --{8-random characters}

(Note: %AppDataLocal% is the Local Application Data folder, which is usually C:\Documents and Settings\{user name}\Local Settings\Application Data on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\Users\{user name}\AppData\Local on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit).. %System% is the Windows system folder, where it usually is C:\Windows\System32 on all Windows operating system versions.)

It creates the following folders:

• If the sample is executed without administrative privileges:
  • %AppDataLocal%\{string1}{string2}

(Note: %AppDataLocal% is the Local Application Data folder, which is usually C:\Documents and Settings\{user name}\Local Settings\Application Data on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\Users\{user name}\AppData\Local on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit).)

It executes then deletes itself afterward.

It adds the following mutexes to ensure that only one of its copies runs at any one time:

• Global\I{Volume Serial Number}
• Global\M{Volume Serial Number}

Autostart Technique

This Trojan Spy registers itself as a system service to ensure its automatic execution at every system startup by adding the following registry entries:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\{string1}{string2}
ImagePath = %System%\{string1}{string2}.exe

It adds the following registry entries to enable its automatic execution at every system startup:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\
Windows\CurrentVersion\Run
{string1}{string2} = %AppDataLocal%\{string1}{string2}\{string1}{string2}.exe

Propagation

This Trojan Spy does not have any propagation routine.

Backdoor Routine

This Trojan Spy does not have any backdoor routine.
