NAME

unhide-tcp — forensic tool to find hidden TCP/UDP ports

CONTENTS

SYNOPSIS

unhide-tcp [options]

DESCRIPTION

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.
Note : If iproute2 is not available on the system, option -n or -s SHOULD be given on the command line.

OPTIONS

-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
-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.
