Zircolite is a standalone tool written in Python 3 that allows you to use SIGMA rules on:

• MS Windows EVTX (EVTX, XML, and JSONL formats)
• Auditd logs
• Sysmon for Linux
• EVTXtract
• CSV and XML logs

• Fast Processing: Zircolite is relatively fast and can parse large datasets in just seconds.
• SIGMA Backend: It is based on a SIGMA backend (SQLite) and does not use internal SIGMA-to-something conversion.
• Advanced Log Manipulation: It can manipulate input logs by splitting fields and applying transformations, allowing for more flexible and powerful log analysis.
• Flexible Export: Zircolite can export results to multiple formats using Jinja templates, including JSON, CSV, JSONL, Splunk, Elastic, Zinc, Timesketch, and more.

You can use Zircolite directly in Python or use the binaries provided in the releases.

Documentation is available here (dedicated site) or here (repo directory).

The project has only beek tested with Python 3.10. If you only want to use base functionnalities of Zircolite, you can install dependencies with : pip3 install -r requirements.txt. But pip3 install -r requirements.full.txt is strongly recommended.

The use of evtx_dump is optional but required by default (because it is -for now- much faster), If you do not want to use it you have to use the --noexternal option. The tool is provided if you clone the Zircolite repository (the official repository is here).

⚠️ On some systems (Mac, Arm, ...) the evtx library may need Rust and Cargo to be installed.

Check tutorials made by other (EN, SP and FR) here.

Help is available with:

python3 zircolite.py -h

If your EVTX files have the extension ".evtx" :

# python3 zircolite.py --evtx <EVTX FOLDER or EVTX FILE> --ruleset <SIGMA RULESET> [--ruleset <OTHER RULESET>]
python3 zircolite.py --evtx sysmon.evtx --ruleset rules/rules_windows_sysmon_pysigma.json

• The --evtx argument can be a file or a folder. If it is a folder, all EVTX files in the current folder and subfolders will be selected.
• The SYSMON ruleset used is a default one, intended for analyzing logs from endpoints with SYSMON installed.

# For Auditd logs
python3 zircolite.py --events auditd.log --ruleset rules/rules_linux.json --auditd
# For Sysmon for Linux logs
python3 zircolite.py --events sysmon.log --ruleset rules/rules_linux.json --sysmon4linux
# For JSONL or NDJSON logs
python3 zircolite.py --events <JSON_FOLDER_OR_FILE> --ruleset rules/rules_windows_sysmon_pysigma.json --jsononly

• The --events argument can be a file or a folder. If it is a folder, all event files in the current folder and subfolders will be selected.

# Pull docker image
docker pull wagga40/zircolite:latest
# If your logs and rules are in a specific directory
docker run --rm --tty \
    -v $PWD:/case/input:ro \
    -v $PWD:/case/output \
    wagga40/zircolite:latest \
    -e /case/input \
    -o /case/output/detected_events.json \
    -r /case/input/a_sigma_rule.yml

• Replace $PWD with the directory (absolute path only) where your logs and rules/rulesets are stored.

python3 zircolite.py -U

The Mini-GUI can be used totally offline. It allows you to display and search results. You can automatically generate a Mini-GUI "package" with the --package option. To learn how to use the Mini-GUI, check the docs here.
