unhide-tcp — forensic tool to find hidden TCP/UDP ports
unhide-tcp is a forensic tool that identifies TCP/UDP ports that are listening but are not listed by /sbin/ss (or alternatively by /bin/netstat) through brute forcing of all TCP/UDP ports available. Note1 : On FreeBSD ans OpenBSD, netstat is always used as iproute2 doesn't exist on these OS. In addition, on FreeBSD, sockstat is used instead of fuser. Note2 : If iproute2 is not available on the system, option -n or -s SHOULD be given on the command line.
-h --help Display help --brief Don't display warning messages, that's the default behavior. -f --fuser Display fuser output (if available) for the hidden port On FreeBSD, instead of fuser command, displays the output of the sockstat command for the hidden port. -l --lsof Display lsof output (if available) for the hidden port -n --netstat Use /bin/netstat instead of /sbin/ss. On system with many opened ports, this can slow down the test dramatically. -s --server Use a very quick strategy of scanning. On system with a lot of opened ports, it is hundreds times faster than ss method and ten thousands times faster than netstat method. -o --log Write a log file (unhide-tcp-AAAA-MM-DD.log) in the current directory. -V --version Show version and exit -v --verbose Be verbose, display warning message (default : don't display). This option may be repeated more than once. Exit status: 0 if no hidden port is found, 4 if one or more hidden TCP port(s) is(are) found, 8 if one or more hidden UDP port(s) is(are) found, 12 if one or more hidden TCP and UDP ports are found.
