Intel Search

Quickly search CrowdStrike Falcon Intelligence data for string matches. Displays lists of matches and extended details for individual records when only one result is returned. When a value for output prefix (-o) is provided, results will also be written to individual files in CSV format.

Running the program

In order to run this demonstration, you you will need access to CrowdStrike API keys with the following scopes:

Service Collection
Scope

Actors (Falcon Intelligence)

READ

Indicators (Falcon Intelligence)

READ

Reports (Falcon Intelligence)

READ

Required Python libraries

In addition to FalconPy (crowdstrike-falconpy), this application requires the following Python packages:

  • pyfiglet

  • tabulate

  • termcolor

Execution syntax

This sample leverages simple command-line arguments to implement functionality.

Basic usage

Search for all actors, indicators and reports containing the string spider.

python3 intel_search.py -k $FALCON_CLIENT_ID -s $FALCON_CLIENT_SECRET -f spider

Providing a file prefix with the -o argument will also output the results in CSV format to individual files.

python3 intel_search.py -k $FALCON_CLIENT_ID -s $FALCON_CLIENT_SECRET -f spider -o example

Result

Searching Falcon Threat Intelligence for spider.
