Using NtCreateThreadEx for Remote Thread Execution in System Process for Vista & Windows7
Author: tnagareshwar # Views: 57315

Some times back I wrote article on using lesser known method, NTCreateThreadEx for remote thread execution. This is better alternative compared to CreateRemoteThread especially for Vista & Windows 7. As you may aware CreateRemoteThread was the popular method used for DLL Injection.

Here are some of the highlights of this technique

* Major advantage is that it can work across session boundaries while CreateRemoteThread cannot.

* User need to have sufficient privileges to perform tasks such as DLL injection using this method.

* It is UNDOCUMENTED-  there is a risk but it is worth it.

This article explains everything you need to know about NtCreateThreadEx with complete code example.
