Ghost XP works by exploiting a flaw in the way the Windows Registry handles ACLs (access control lists). ACLs are used to specify which users and groups have access to a particular registry key. Ghost XP uses a specially crafted registry key to grant itself access to a system-level registry key that is normally protected from unauthorized access.
Once it has access to this system-level key, Ghost XP can run any code it wants with elevated privileges. This can allow an attacker to take control of the computer, install malware, or steal sensitive data.
Ghost XP is a very serious exploit that can have a significant impact on the security of a Windows computer. Microsoft has released a patch to fix this exploit, but many computers have not yet been patched. If you are running Windows, it is important to make sure that you are using the latest security updates to protect yourself from this exploit.
Here are some ways to protect yourself from Ghost XP:
* Make sure that you are using the latest Windows security updates.
* Do not open attachments or click on links in emails from people you do not know.
* Be careful about what websites you visit.
* Use a strong password and do not share it with anyone.
If you think that your computer may have been infected with Ghost XP, you should immediately scan it with a reputable antivirus program.
