Git AV Scan Action

Action and Dockerfile to scan Git HEAD or commit history using ClamAV. ClamAV® is an open-source antivirus engine for detecting trojans, viruses, malware & other malicious threats.

Disclaimer

This is a proof of concept, and does not provide any guarantee that carefully hidden objects will be scanned. Strong endpoint security, access, and code review policies and practices are the most effective way to ensure that malicious files or code is not introduced into a repository.

This project is not affiliated with the official ClamAV project.

Example usage

uses: djdefi/gitavscan@main
with:
  full: '--full'

Example workflow

Deep history scan. Scans each commit in the repositry history. Slow but thorough:

on: [push]

jobs:
  gitavscan:
    runs-on: ubuntu-latest
    name: History AV Scan
    steps:
    - uses: actions/checkout@v3
      with:
        fetch-depth: '0'
    - name: Git AV Scan
      uses: djdefi/gitavscan@main
      with:
        full: '--full'

Scan current HEAD only. Only the most recent commit pushed will be scanned. Best used with an enforced linear history, or by disabling PR merges in a repository. Fast but misses deeper history:

on: [push]

jobs:
  gitavscan:
    runs-on: ubuntu-latest
    name: AV scan
    steps:
    - uses: actions/checkout@v3
    - name: Git AV Scan
      uses: djdefi/gitavscan@main

Running locally with Docker

Build:

docker build -t gitavscan .

Run full scan:

docker run --rm -it -v /path/to/repo:/scandir gitavscan --full
