netcat is a general purpose networking tool that lets you easily create new network daemons and clients without doing the plumbing yourself.

It is popular for creating simple back doors that essentiall do 'run cmd.exe when you get a request on TCP/XXX'

Full details are at http://netcat.sourceforge.net/

Some other popular ones are Subseven, Back Oriface, Back Oriface 2000, Netbus, and Netbus II, but there are literally hundreds.


There's a really good overview at http://www.commodon.com/threat/threat-bground.htm

Also, to see details on lots of differnt trojans/backdoors, try http://xforce.iss.net/xforce/search.php and search for 'backdoor'.

Umm..hold up
You ask about netcat and are provided a link that explains how it works. Yet because it's not a tutorial you aren't satisfied?

Maybe you should google for ' A Lazy Mans Guide to Hacking.'






I will apologize to all involved if I have offended anyone ,but it seems an odd response to 'chris_calabrese's ' first excellant reply.

baburkhan,
This site does not allow request for trojan programming.  I will delete that portion of your request.  I need you to signify here within 72 hours that you understand this and will comply in the future.  Failure to do so will obligate me to turn your account over to site administration for review.
