Short description

The trojan serves as a proxy server.

Installation

When executed, the trojan creates the following files:
  • %system%clbcoko.dll
  • %system%driversmrxoko.sys
  • %temp%w3oko.bat
The trojan registers itself as a system service using the following filename:
  • DHCP Shortcut List Redirector
The trojan executes the following commands:
  • netsh firewall add allowedprogram name="ST330 OKO service" program="%SystemRoot%system32svchost.exe" mode=ENABLE
  • netsh firewall add portopening tcp 8085 "MyOKOPort" ENABLE
The performed command creates an exception in the Windows Firewall.

The following Registry entries are created:
  • [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServices
    swoko]
    "FailureActions" = 00000000000000000000000003000000140000000100000060EA00000100000060EA00000100000060EA0000
  • [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServices
    swokoParameters]
    "ServiceDll" = "%system%clbcoko.dll"
  • [HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersion
    Svchost]
    "termsvc" = "swoko"


The trojan deletes the original file.
