RITA (Real Intelligence Threat Analytics) in Jupyter Notebook

RITA is an open source framework for network traffic analysis sponsored by Active Countermeasures

RITA-J is the implementation of RITA features in Jupyter Notebook. The goal is to support all types of Firewall/Proxy/DNS logs that are in CSV, TSV, or JSON format, and make it easy to analyze, hunt and detect potential C2 activity without installing additional hardware and other components to maintain.

The sample dataset was shared by Ali Alwashali (@ali_alwashali). It contains:

• Zeek logs from malware-traffic-analysis.net PCAP files, from 2013 to 2021
• Suricata alerts triggered by the PCAP analysis

Features

• Beaconing Detection: Search for signs of beaconing behavior in and out of your network
• DNS Tunneling Detection Search for signs of DNS based covert channels (TO DO)
• Blacklist Checking: Query blacklists to search for suspicious domains and hosts (TO DO)
• More features will be added

Requirements

Firewall/Proxy logs that are in CSV or JSON format. If the logs are not parsed, parsing is required before analysis.
The notebook(s) support CSV files. JSON requires manuel mapping. Some helpful resources for reading and parsing JSON files:

• https://www.w3schools.com/python/pandas/pandas_json.asp
• https://towardsdatascience.com/how-to-parse-json-data-with-python-pandas-f84fbd0b1025
• https://towardsdatascience.com/how-to-convert-json-into-a-pandas-dataframe-100b2ae1e0d8

Acquiring Logs and Working with different log formats

There are several ways to acquire logs.

• Reading from SIEM / DB / API
  • https://infosecjupyterthon.com/workshops/day1/day1-2-Acquiring-data.html
• Export logs from SIEM in CSV/JSON
• Send logs to a Syslog server/connector -> parse -> export it to CSV/JSON file
• Export logs directly to a file, then convert it to CSV/JSON

An example for converting Fortinet logs:
