Rustinel

Open-source endpoint detection. Three platforms. Your rules.
Run Sigma, YARA, and IOC detections on native Windows, Linux, and macOS telemetry.
Written in Rust, with local alerts and no cloud account required.

Why Rustinel?

• Use Sigma and YARA rules. Sigma for behavior, YARA for executables and process memory, and IOC lists for hashes, IPs, domains, and paths.
• Run on Windows, Linux, and macOS. One engine, one config format, and the same Sysmon-style field names everywhere. Coverage varies by platform.
• Keep your data. The agent sends nothing home. Alerts are local ECS NDJSON files that Elastic, Splunk, or any log pipeline can ingest.
• Test rules against recorded behavior. Capture activity once, then replay it on any machine as your rules change.
• See the gaps. rustinel sigma doctor explains which rules can fire, while rustinel doctor reports runtime health and events dropped under load.

Quickstart

Install into a local rustinel folder, then start it.

Linux (kernel 5.8+):

curl -fsSL https://rustinel.io/install.sh | sh
cd rustinel && sudo ./rustinel run

Windows, in an elevated PowerShell:

irm https://rustinel.io/install.ps1 | iex
Set-Location rustinel; .\rustinel.exe run

macOS (experimental) needs Full Disk Access first, see macOS permissions:

curl -fsSL https://rustinel.io/install.sh | sh
cd rustinel && sudo ./rustinel run

Run whoami in another terminal. The demo rule fires and the alert lands in rustinel/logs/alerts.json.<date>.

To install it as a service with a real rules pack, stop it with Ctrl-C and run sudo ./rustinel setup --yes from the rustinel folder (.\rustinel.exe setup --yes on Windows). See Deploy on an endpoint.

Capture once, replay as your rules improve

sudo ./rustinel capture --output ~/captures/session.ndjson   # Ctrl-C when done
sudo chown -R "$USER" ~/captures
./rustinel replay ~/captures/session.ndjson
./rustinel replay ~/captures/session.ndjson --config candidate.toml

Replay needs no privileges and works across platforms: a Windows recording replays on Linux. See Test rules with replay.

Platform support

Platform	Sensors	Telemetry	Status
Windows 10/11, Server 2016+	ETW + Windows Event Log	Process, image load, network, file, registry, DNS, PowerShell, WMI, service, task, Security audit events	Stable
Linux 5.8+	eBPF	Process, network, file, DNS	Stable
macOS 11+	Endpoint Security + /dev/bpf	Process, file, network, DNS	Experimental

Know the boundaries

Rustinel is built for endpoint monitoring, detection engineering, labs, and SIEM pipeline testing. It is not a replacement for a commercial EDR: it has no anti-tamper, no pre-execution blocking, and no management console. See the Security model.
