Megatron is a tool implemented by CERT-SE which collects and analyses log files with bad machines, e.g. from Shadowserver. Apart from abuse mail handling, Megatron can be used to collect statistics, convert log files, and do log file analysis during incident handling.
Major features:
- Flexible parsing: many input sources are supported without any coding. Regular expressions are used to extract tokens which are bound to variables. A variable corresponds to a field in the database and can be used in for example filters and templates.
- Organization matching: Megatron tries to match every input record to an organization using its IP-blocks, ASNs, and domain names. Each organization have a priority which makes it possible to filter out important records.
- Database: input records are stored in a relational database (MySQL is default), making data mining possible.
- Filtering: a wide variety of filters can be used to filter input records.
- Data decoration: data may be added to the record before it is saved to the database. Types of lookups: IP to ASN, IP to country code, IP to hostname, hostname to IP, URL to hostname, hostname to country code, and IP to geolocation (longitude, latitude, and city). Three of MaxMind's databases are supported (ASN, City, and Country).
- Performance: large data volumes can be handled. All lookups except DNS queries are local, for instance ASN lookups uses database queries by importing a BGP routing table to the database.
For all features, see readme-general.txt
Convert a file with IP addresses to a pipe-separated file with IP, AS, country code, and hostname:
$ megatron.sh --job-type ip-flowing --export --no-db test-data/multiple-ips-per-line3.log
As above but output file is tab-separated and contains geolocation data:
$ megatron.sh --job-type ip-flowing-verbose --export --no-db test-data/multiple-ips-per-line3.log
Prints information about two IP addresses (hostnames or URLs works as well):
$ megatron.sh --whois 130.238.7.133 217.21.237.35
IP | AS | CC | Hostname | AS Name | Organization
130.238.7.133 | 1653 | SE | live.webb.uu.se | SUNET Swedish University Network | Uppsala universitet
217.21.237.35 | 29672 | SE | stockholm.se | S:t Erik Kommunikation AB | Stockholms stad
Prints information about URLs in specified file:
$ megatron.sh --whois infection-urls.txt
Process file and save result in the database:
$ megatron.sh --job-type shadowserver-drone test-data/2009-06-08-drone-report-se.log
Preview of mail to be sent:
$ megatron.sh --job shadowserver-drone_2013-06-22_160142 --id 4242 --mail-dry-run
Send emails for the job:
$ megatron.sh --job shadowserver-drone_2009-06-22_160142 --id 4242 --mail
Megatron is designed to automate day-to-day abuse handling. Running Megatron from the command line is only necessary in special cases.

Megatron is cross-platform as it is implemented in Java and Python. It has been tested on Windows 7 and Ubuntu 12.04. Megatron requires a MySQL database. Do not worry, the installation is easy and described in detail in this document: readme-install.txt
