ARStack61850 is an IEC 61850 engineering and laboratory toolkit. Report suspected vulnerabilities privately so maintainers can investigate without exposing operators or deployments.

Use GitHub's Report a vulnerability / private security advisory option for this repository if it is available. If private reporting is unavailable, contact the repository maintainer through a private channel rather than posting exploit details, secrets or sensitive packet captures in a public issue.

A useful report includes the affected release/commit, relevant component, reproduction steps, observed impact and a minimal non-sensitive test case. Do not include live substation addresses, passwords, private keys or customer engineering files.

The latest Stable release is the recommended published version. Earlier releases and development branches may differ; security fixes, when available, will be documented with their release.

Perform network tests only in an isolated laboratory or with explicit permission from the system owner. ARStack simulation of a PTP Grandmaster does not establish GPS traceability, an approved field clock reference, or certification for production protection systems.

For routine bugs, feature ideas or interoperability reports that do not disclose a vulnerability, use the public issue tracker.
