NAME

Masscan::Scanner - A Perl module which helps in using the masscan port scanner.

VERSION

version 20200329.150259

SYNOPSIS

use Masscan::Scanner;

my @hosts     = qw(::1 127.0.0.1);
my @ports     = qw(22 80 443 1-100);
my @arguments = qw(--banners);

my $mas = Masscan::Scanner->new(hosts => \@hosts, ports => \@ports, arguments => \@arguments);

# Add extra hosts or ports
$mas->add_host('10.0.0.1');
$mas->add_host('10.0.0.0/24');
$mas->add_port(25);
$mas->add_port(110);

# Can add port ranges too
$mas->add_port('1024-2048');
$mas->add_port('3000-65535');

# Can add domains but will incur a performance penalty hence IP(s) and CIDR(s) recommended.
# When a domain is added to the list of hosts to be scanned this module will attempt to
# resolve all of the A records for the domain name provided and then add the IP(s) to the
# scan list.
$mas->add_host('averna.id.au');
$mas->add_host('duckduckgo.com');

# It is usually required that masscan is run as a privilaged user.
# Obviously this module can be successfully run as the root user.
# However, if this is being run by an unprivilaged user then sudo can be enabled.
#
# PLEASE NOTE: This module assumes the user can run the masscan command without
# providing their password. Usually this is achieved by permitting the user to
# run masscan within the /etc/sudoers file like so:a
#
# In /etc/sudoers: user averna = (root) NOPASSWD: /usr/bin/masscan
$mas->sudo(1);

# Turn on verbose mode
# Default is off
$mas->verbose(1);

# Add extra masscan arguments
$mas->add_argument('--rate 100000');

# Set the full path to masscan binary
# Default is the module will automatically find the binary full path if it's
# withing the users environment path.
$mas->binary('/usr/bin/masscan');

# Set the name servers to be used for DNS resolution
# Default is to use a list of public DNS servers.
$mas->name_servers(['192.168.0.100', '192.168.0.101']);

# Will initiate the masscan.
# If the scan is successful returns True otherwise returns False.
my $scan = $mas->scan;

# Returns the scan results
my $res = $mas->scan_results if ($scan);

METHODS

add_host

This method allows the addition of a host to the host list to be scaned.

my $mas = Masscan::Scanner->new();
$mas->add_host('127.0.0.1');

add_port

This method allows the addition of a port or port range to the port list to be scaned.

my $mas = Masscan::Scanner->new();
$mas->add_port(443);
$mas->add_port('1-65535');

add_argument

This method allows the addition of masscan command line arguments.

my $mas = Masscan::Scanner->new(hosts => ['127.0.0.1', '10.0.0.1'], ports => [80. 443]);
$mas->add_argument('--banners');
$mas->add_argument('--rate 100000');

scan

Will initiate the scan of what hosts & ports have been provided.
Returns true fi the scan was successful otherwise returns false.

my $mas = Masscan::Scanner->new();
$mas->hosts(['127.0.0.1', '::1']);
$mas->ports(['22', '80', '443']);
$mas->add_port('1024');

$mas->scan;

scan_results

Returns the result of the masscan as a Perl data structure.

my $mas = Masscan::Scanner->new();
$mas->hosts(['127.0.0.1', '::1']);
$mas->ports(['22', '80', '443']);
$mas->add_port('1024');

my $scan = $mas->scan;

if ($scan)
{
    my $res = $mas->scan_results;
}

SCAN RESULTS

The scan_results method returns a data structure like so:

{
    'scan_results' => [
                          {
                            'timestamp' => '1584816181',
