Giving you the chance to rapidly respond and protect yourself and your users. 7 | 8 | For further reading about ChainAlert check out our [blog](https://medium.com/checkmarx-security/chainalert-our-response-to-npm-account-takeover-attacks-aa1d10a4fdbe). 9 | ### The Need 10 | 11 | Recent package takeover incidents such as [coa](https://checkmarx.com/blog/attackers-write-bugs-as-well/) and [ua-parser-js](https://checkmarx.com/blog/uaparser-js-attack-preparations/) have stressed the need for an alarm system to alert developers and users. 12 | 13 | Learning the lessons of these supply chain incidents we've created **ChainAlert**, a monitoring service that will help minimize the damages from those attacks by closing the gap between takeover to detection and mitigation. 14 | 15 | 16 | ### What It Does? 17 | 18 | ChainAlert cloud service continuously monitor and analyse new releases of packages: 19 | - Detection of newly added auto install scripts such as `install`, `preinstall`, `postinstall` 20 | - Checking the consistency of the version and if presented in the package's linked git repository tags 21 | - Changes in package maintainers 22 | 23 | ![Group 468](https://user-images.githubusercontent.com/1287098/144894054-1ca132cf-e3f2-448a-bfdb-d04b00cbd02c.png) 24 | 25 | 26 | If ChainAlert finds a suspicious activity of a package, it will automatically open GitHub issues on: 27 | - The package's linked GitHub repo, to notify the maintainers of that activity 28 | - Any package dependents' GitHub repo who's opted-in via [this GitHub action](https://github.com/marketplace/actions/chainalert) 29 | 30 | ![111](https://user-images.githubusercontent.com/1287098/144894036-8b414468-8a93-464f-bbf9-6961043c91b8.png) 31 | ![Frame 240](https://user-images.githubusercontent.com/1287098/144136718-200904ca-c01f-4bd8-825a-add9762e40dc.png) 32 | 33 | 34 | ### How Do I Opt In? 35 | 36 | You need to add our [GitHub action](https://github.com/marketplace/actions/chainalert) to your project as a cron job. 37 | 38 | Create a dedicated workflow file under `.github/workflows/chainalert.yml` 39 | 40 | ```yml 41 | name: ChainAlert 42 | on: 43 | schedule: 44 | - cron: '0 0 * * *' 45 | push: 46 | branches: [ master ] 47 | jobs: 48 | chainalert: 49 | runs-on: ubuntu-latest 50 | steps: 51 | - uses: actions/checkout@v2 52 | - uses: checkmarx/chainalert-github-action@v1 53 | ``` 54 | - 💡 This action and service are only available for public GitHub projects 55 | - 💡 If our service stops receiving for more than 2 days, we will automatically opt you out 56 | 57 | 58 | ### Features 59 | - NPM packages support 60 | 61 | #### WIP 62 | - PyPi packages support 63 | - Private repos support 64 | - Automatic pull-requests 65 | 66 | 67 | ### Contact 68 | For any further question please feel free to open an issue or contact us at supplychainsecurity@checkmarx.com 69 | 70 | -------------------------------------------------------------------------------- /LICENSE.txt: -------------------------------------------------------------------------------- 1 | Apache License 2 | Version 2.0, January 2004 3 | http://www.apache.org/licenses/ 4 | 5 | TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 6 | 7 | 1.
