Nazwa: W32.Wapomi.C
Typ: Robak
Źródło: Symantec
System: Windows

Działanie:
Po uruchomieniu sprawdza statusy usług:

Kod: Zaznacz cały

    * AppMgmt (appmgmts.dll)
    * BITS (qmgr.dll)
    * Browser (browser.dll)
    * CryptSvc (cryptsvc.dll)
    * EventSystem (es.dll)
    * FastUserSwitchingCompatibility (shsvcs.dll)
    * helpsvc (pchsvc.dll)
    * Netman (netman.dll)
    * Nla (mswsock.dll)
    * Ntmssvc (ntmssvc.dll)
    * RemoteRegistry (regsvc.dll)
    * Schedule (schedsvc.dll)
    * SSDPSRV (ssdpsrv.dll)
    * Tapisrv (tapisrv.dll)
    * upnphost (upnphost.dll)
    * WmdmPmSN (mspmsnsv.dll)
    * xmlprov (xmlprov.dll)



Gdy znajdzie nieuruchomioną usługę, podmienia jej DLL ze swoją kopią i restartuje usługę.

Tworzy plik i ukrywa w nim Hacktool.Rootkit:
%Windir%\[RANDOM CHARACTERS].sys

Dodaje klucze rejestru:

Kod: Zaznacz cały

    * HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\[RANDOM CHARACTERS]\"ImagePath" = "%SystemRoot%\[RANDOM CHARACTERS].sys"
    * HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\[RANDOM CHARACTERS]\"Start" = "3"
    * HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\[RANDOM CHARACTERS]\"Type" = "1"


Zmienia wpisy w rejestrze aby wyłączyć ochronę antywirusową:
