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 allways 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
- 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.
- if no hidden port is found,
- if one or more hidden TCP port(s) is(are) found,
- if one or more hidden UDP port(s) is(are) found,
- if one or more hidden TCP and UDP ports are found.
