NAME

Net::Abuse::Utils - Routines useful for processing network abuse

VERSION

version 0.27

SYNOPSIS

    use Net::Abuse::Utils qw( :all );
    print "IP Whois Contacts: ", join( ' ', get_ipwi_contacts($ip) ), "\n";
    print "Abuse.net Contacts: ", get_abusenet_contact($domain), "\n";

DESCRIPTION

Net::Abuse::Utils provides serveral functions useful for determining information about an IP address including contact/reporting addresses, ASN/network info, reverse dns, and DNSBL listing status. Functions which take an IP accept either IPv6 or IPv4 IPs unless indicated otherwise.

CONFIGURATION

There is a @RESOLVERS package variable you can use to specify name servers different than the systems nameservers for queries from this module. If you intend to use Google's nameservers here, please see This issue on GitHub for a note of caution <https://github.com/mikegrb/Net-Abuse-Utils/issues/9#issuecomment-24387435>.

FUNCTIONS

The following functions are exportable from this module. You may import all of them into your namespace with the ":all" tag.

get_asn_info ( IP )

Returns a list containing (ASN, Network/Mask, CC code, RIR, modified date) for the network announcing "IP".

get_all_asn_info ( IP )

Returns a reference to a list of listrefs containting ASN(s), Network,Mask, CC code, RIR, and modified date fall all networks announcing "IP".

get_peer_info ( IP )

IPv4 Only. Returns an array of hash references containing (ASN, Network/Mask, CC code, RIR, modified date) for the peers of the network announcing "IP".

get_as_description ( ASN )

Returns the AS description for "ASN".

get_as_company ( ASN )

Similiar to "get_as_description" but attempts to clean it up some before returning it.

get_soa_contact( IP )

Returns the SOA contact email address for the reverse DNS /24 zone containing "IP".

get_ipwi_contacts( IP )

Returns a list of all email addresses found in whois information for "IP" with duplicates removed.

get_rdns( IP )

Returns the reverse PTR for "IP".

get_dnsbl_listing( IP, DNSBL zone )

IPv4 Only. Returns the listing text for "IP" for the designated DNSBL. "DNSBL zone" should be the zone used for looking up addresses in the blocking list.

get_ip_country( IP )

Returns the 2 letter country code for "IP".

get_asn_country( ASN )

Returns the 2 letter country code for "ASN".

get_abusenet_contact ( domain )

Returns the abuse.net listed contact email addresses for "domain".

is_ip ( IP )

Returns true if "IP" looks like an IP, false otherwise.

get_domain ( IP )

Takes a hostname and attempts to return the domain name.

get_malware ( md5 )

Takes a malware md5 hash and tests it against http://www.team-cymru.org/Services/MHR. Returns a HASHREF of last_seen and detection_rate.

DIAGNOSTICS

Each subroutine will return undef if unsuccessful. In the future, debugging output will be available.

CONFIGURATION AND ENVIRONMENT

There are two commented out lines that can be uncommented to enable Memoize support. I haven't yet decided whether to include this option by default. It may be made available in the future via an import flag to use.

DEPENDENCIES

This module makes use of the following modules:

Net::IP, Net::DNS, Net::Whois::IP, and Email::Address::XS

BUGS AND LIMITATIONS

There are no known bugs in this module. Please report problems to Michael Greb (mgreb@linode.com)
