[Firehol Sweep]

Generate a CSV file containing possible malicious IP addresses using FireHOL's blocklist IP sets.

Description

Simply put, this gathers a list of possible malicious IP addresses using the datasets on GitHub gathered by FireHOL. This can be used in Splunk to sweep you environment or setup alerts when traffic is detected.

Prerequisites

• Bash
• Curl
• Git

Setup

Open a terminal and run the following commands:

git clone https://github.com/ecstatic-nobel/Firehol-Sweep.git
cd Firehol-Sweep

If you want to change the source of the IP sets:

• Navigate to FireHOL's blocklist-ipset GitHub project
• Paste the name of the IP set on a separate line in firehol_ipsets.txt

Create the Lookup Table

To run the script, run the following command from the project directory:

bash create_lookup.sh CLONEDIR OUTPUTFILE

The CLONEDIR is the directory where you want to clone the FireHOL blocklist-ipsets project. The OUTPUTFILE is the path to the new lookup table that will be generated. A sample lookup table can be found here.

Destroy

To remove the project completely, run the following commands:

rm -rf Firehol-Sweep
