One of the default options is the installation as a persistent threat. In most cases this means that the virus engine will be started every time the computer is powered on. In some cases it can also disable access to the recovery boot options which makes recovery even more difficult.

The next module which is started is the anti-analysis function which will scan the memory and hard disk contents looking for active security software that can potentially block or remove the GootKit Trojan. All found apps will be bypassed or entirely deleted from the system. Examples of such include virtual machine hosts, antivirus software, firewalls, intrusiedetectiesystemen en etc. As this is related to advanced system interaction the following actions can be caused:

  • werkwijze Hookup — The GotKit Trojan can hookup to existing (lopend) processes that include both system and third-party ones.

  • System Wijzigingen — As a result of the GootKit Trojan installation its engine can be configured into editing out system configuration files, editing the user preferences or making edits to the Windows Registry values. This can result in serious issues when interacting with the computer, performance problems, loss of data and even unexpected errors.

One of the newer releases of the GootKit Trojan adds in a further module that will bypass Windows Defender by using a complex technique. First it will check if the service is running and if this checks as positive a Registry entries will be added that is related to a weakness in the system. It allows the whitelisting of services at boot-up. Using a malware dropper that has been specially made for this purpose the Windows Defender service will be shut down.
