Übertragungsdetails

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

Installation

Schleust die folgenden Eigenkopien in das betroffene System ein:

• If sample executed with administrative privileges:
  • %System%\{String1}{String2}.exe
• If sample executed without administrative privileges:
  • %AppDataLocal%\{String1}{String2}\{String1}{String2}.exe

(Hinweis: %System% ist der Windows Systemordner. Er lautet in der Regel C:\Windows\System unter Windows 98 und ME, C:\WINNT\System32 unter Windows NT und 2000 sowie C:\Windows\System32 unter Windows 2000(32-bit), XP, Server 2003(32-bit), Vista, 7, 8, 8.1, 2008(64-bit), 2012(64bit) and 10(64-bit).)

Fügt die folgenden Prozesse hinzu:

• {Malware file path}\{Malware file name}.exe --{8 Random Characters}
• If sample executed with administrative privileges:
  • %System%\{String1}{String2}.exe
  • %System%\{String1}{String2}.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}

(Hinweis: %System% ist der Windows Systemordner. Er lautet in der Regel C:\Windows\System unter Windows 98 und ME, C:\WINNT\System32 unter Windows NT und 2000 sowie C:\Windows\System32 unter Windows 2000(32-bit), XP, Server 2003(32-bit), Vista, 7, 8, 8.1, 2008(64-bit), 2012(64bit) and 10(64-bit).)

Erstellt die folgenden Ordner:

• If the sample is executed without administrative privileges:
  • %AppDataLocal%\{String1}{String2}

Wird ausgeführt und löscht sich dann selbst.

Fügt die folgenden Mutexe hinzu, damit nur jeweils eine ihrer Kopien ausgeführt wird:

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

Autostart-Technik

Registriert sich als Systemdienst, damit sie bei jedem Systemstart automatisch ausgeführt wird, indem sie die folgenden Registrierungseinträge hinzufügt:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\{String1}{String2}
ImagePath = %System%\{String1}{String2}.exe

Fügt folgende Registrierungseinträge hinzu, um bei jedem Systemstart automatisch ausgeführt zu werden.

HKEY_CURRENT_USER\SOFTWARE\Microsoft\
Windows\CurrentVersion\Run
{String1}{String2} = %AppDataLocal%\{String1}{String2}\{String1}{String2}.exe
