I will describe how to find a little guide a Terminal Server service and perform a dictionary attack dintrun Linux.Metode system are many, here I will describe only one. I will use that tool for rdesktop 1.4.1. Linux will be added to make a patch for dictionary attack.
Rdesktop 1.4.1 pueti you find on the internet but this will put a link where you can take with tabs and a built-in patch
The first thing you need to do is to find a terminal server, which is a default on TCP port 3389
You can use the following command for Nmap, or depends on what scanner you use.
TerminalServer.txt-oN nmap-p 3389 - open 192.168.0.0/24
where instead of 192.168.0.0/24 IPs you specify that you want to scanners. Nmap will save all tabs TerminalServer.txt meet.
Another command is:
PS3389-nmap-iR 0-p 3389 - open-oN TerminalServer.txt
instead of 0 put each ip you want to scan. (The default 0 will scan forever) And in this case saves everything TerminalService.txt Nmap, The - - is open to only show open service.
Once you have enough targets to phase No. 2 passing attack Dictionary.
You have to remove the archive with the command
Then go where you opened the archive,
And give the following command for patch
Now you have to compile:
. / Configure
after you have finished give rdesktop command and will show all the options.
rdesktop-u administrator-p 192.168.1.1 pass.txt
dictionary of words which is pass.txt
An administator will set it so that some will allow only a few attempts and close the rest.
This is illegal, you should be licensed before doing a scan on any network.
Everything can be saved In a log file.
