Dateien Eine Kopie seiner selbst wird hier erzeugt:
• %SYSDIR%\IRQconf.exe

Die anfänglich ausgeführte Kopie der Malware wird gelöscht.

Es werden folgende Dateien erstellt:

– c:\a.bat Des weiteren wird sie ausgeführt nachdem sie vollständig erstellt wurde. Erkannt als: BAT/REG.Zapchast

– C:\DOCUME~1\name1252\LOCALS~1\Temp\1.reg Des weiteren wird sie ausgeführt nachdem sie vollständig erstellt wurde. Enthält von der Malware genutzte Parameter. Erkannt als: TR/TCPParams.D.3

Registry Die folgenden Registryschlüssel werden in einer Endlosschleife fortlaufen hinzugefügt um die Prozesse nach einem Neustart des Systems erneut zu starten.

– [HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
   • "IRQ Assigning Agent"="IRQconf.exe"

– [HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices]
   • "IRQ Assigning Agent"="IRQconf.exe"

Folgender Registryschlüssel wird hinzugefügt:

– [HKCU\Software\Microsoft\OLE]
