Hawkeye is a project security, vulnerability and general risk highlighting tool. It has a few goals:
- Designed to be entirely extensible by just adding new modules with the correct signature to lib/modules
- Modules return results via a common interface, which permits consolidated reporting and artefact generation
- Should be easy to run, be it via NPM, or Docker, on your Host, or in a CI Server
By all means continue to use this CLI to get scans in your pipeline, but now you can use this hosted version to get scanning even faster!. Some of the benefits of the hosted version are:
- Free (obviously)
- Links to GitHub and scans both Public and Private repositories
- GitHub "Push" scanning
- On-demand one-click scanning
- Scheduled scanning (great for continually checking for new issues in your deployed applications)
- Email notifications when we find new issues
- Consolidated dashboards
Modules are basically little bits of code that either implement their own logic, or wrap a third party tool and standardise the output. They only run if the required criteria are met, for example; the nsp
module would only run if a package.json
is detected in the scan target - as a result, you don't need to tell Hawkeye what type of project you are scanning. The modules implemented so far are:
- File Names (files): Scan the file list recursively, looking for patterns as defined in data.js, taken from gitrob. We're looking for things like
id_rsa
, things that end inpem
, etc. - File Content Patterns (contents): Looks for patterns as defined in data.js within the contents of files, things like 'password: ', and 'BEGIN RSA PRIVATE KEY' will pop up here.
- File Content Entropy (entropy): Scan files for strings with high (Shannon) entropy, which could indicate passwords or secrets stored in the files, for example: 'kwaKM@£rFKAM3(a2klma2d'
- Node Security Project (nsp): Wraps Node Security Project to check your package.json for known vulnerabilities.
- NPM Check Updates (ncu): Wraps NPM Check Updates to check your package.json for outdated modules.
- CrossEnv (node-crossenv): See Node Cross-Env Malware. Checks your package.json for known malicious modules which contain this malware.
- Constant Hash Tables (node-chs): See Node Constant Hashtable. Checks if your package.json can be run against vulnerable versions of node.
- Bundler Audit (bundlerAudit): Wraps Bundler Audit to check your Gemfile/Gemfile.lock for known vulnerabilities.
- Brakeman (brakemanScan): Wraps Brakeman for static analysis security vulnerability scanner for Ruby on Rails applications.
- Safety (safety): Wraps Safety to check your requirements.txt for known vulnerabilities. Unfortunately, safety does not provides a risk level classification of the vulneravilities, so every vulnerability is logged as high.
- Piprot (pythonOutdatedDepScan): Wraps Piprot to check your requirements.txt for outdated dependencies.
- Bandit (banditScan): Wraps Bandit to find common security issues in python code.
I really, really do welcome people writing new modules so please check out lib/modules/example-shell/index.js as an example of how simple it is, and send me a pull request.
- Entropy is disabled by default because it can return a lot of results, which are mostly misses, to run it please use the
-m entropy
switch. Personally I use this manually checking over code bases I have inherited. - We only look inside the contents of files up to 20kb, I plan to add configuration options in the future to allow you to change this.
I wanted Hawkeye to be as flexible as possible, as a result it supports numerous methods of execution.
There are two ways to run Hawkeye from the command line, the first is the easiest if you have nodejs on your host, simply type npm install -g hawkeye-scanner
which will add the hawkeye
binary to your path.
If you don't have nodejs on your machine, or simply don't want anything on your host, you can use docker with docker run --rm -v $PWD:/target stono/hawkeye
.
Note: If you opt for docker and you are on macosx, please be aware that the osxfs
is approx 20x slower than native filesystem access, so if you're scanning a particularly large project you may experience some slow down and the npm
choice would be a better option.
This is where Hawkeye is lovely, lets say you have project which has a Dockerfile
, with lines like this in:
COPY . /app
VOLUME /app
You could add hawkeye to your compose file like this:
services:
app:
build: .
hawkeye:
image: stono/hawkeye
command: scan -t /app
volumes_from:
- app
You can simply do docker-compose run --rm --no-deps hawkeye
. Woo hoo.
This is an example of running Hawkeye against one of your projects in GoCD:
<pipeline name="security-scan">
<stage name="Hawkeye" cleanWorkingDir="true">
<jobs>
<job name="scan">
<tasks>
<exec command="docker">
<arg>pull</arg>
<arg>stono/hawkeye</arg>
<runif status="passed" />
</exec>
<exec command="bash">
<arg>-c</arg>
<arg>docker run --rm -v $PWD:/target stono/hawkeye</arg>
<runif status="passed" />
</exec>
</tasks>
</job>
</jobs>
</stage>
</pipeline>
This is an example of running Hawkeye from package.json against a local repository before commit, failing the commit if high or critical issues are found:
{
"name": "demoproj",
"version": "1.0.0",
"description": "demo",
"main": "app.js",
"dependencies": {
"express": "4.16.2"
},
"devDependencies": {
"pre-commit": "^1.2.2"
},
"scripts": {
"hawkeye:pre-commit": "hawkeye scan -t ./src -m contents -m files -f high"
},
"pre-commit": [
"hawkeye:pre-commit"
],
"author": "",
"license": "ISC"
}
As of version 0.9.0
, you can use the familiar .hawkeyerc
and .hawkeyeignore
pattern in your project root.
This file takes all the same options as hawkeye scan --help
. In this example, we'll run the contents
, entropy
, files
, ncu
and nsp
{
"modules": ["contents", "entropy", "files", "ncu", "nsp"],
"failOn": "medium"
}
This file should be a collection of patterns to exclude from the scan, and is equivalent to running --exclude
.
^test/
README.md
There are a few options available:
Hawkeye by default will attempt to detect a .git folder in your target, if it is there it will only scan git tracked files. Further to that, if a .git-crypt folder is detected, we will also exclude files which are GPG encrypted. If there is no .git in the target directory, then all files will be scanned.
You can override this behaviour with the --all
flag, which will scan all files regardless.
From a pipeline perspective, the --fail-on
command is useful, you might not wish for low
items to break your build, so you could use --fail-on medium
.
By default Hawkeye will look in your current working directory. You can override this behaviour though by specifying a --target
If you want to run specific modules only, you can use the --module
flag, which can be specified multiple times. For example hawkeye scan -m nsp -m ncu
would run just the nsp and ncu modules.
The --json
paramter allows you to write a much more detailed report to a file. See the Json section below for more information
-s, --sumologic http://sumologic-http-collector: Send the results to SumoLogic
This will post the results to a SumoLogic HTTP collector. See the SumoLogic section below for more information.
This parameter (which can be specified multiple times) allows you to specify patterns you wish to be excluded from the scan. For example hawkeye scan -e "^test/"
would exclude all your test files. All paths are relative to the --target
.
There are some global exclusions in place, and those are "^.git", "^.git-crypt" and "^node_modules".
You can view the module status with hawkeye modules
. As previously mentioned you can see that entropy is disabled by default. If you want to run it, use the -m entropy
flag.

Here are some other handy examples:
(hawkeye scan >/dev/null) 2>&1 | tail -n +3 | grep critical
- output just critical items
Another option is for you to use a different output writer, for example...
You can output much more information in the form of a JSON artefact that groups by executed module.
Check out a sample here
The output of Hawkeye can be sent to a SumoLogic HTTP collector of your choice. In this example, I have a collector of hawkeye
, with a single HTTP source.
hawkeye scan --sumo https://collectors.us2.sumologic.com/receiver/v1/http/your-http-collector-url
...
[info] Doing writer: sumologic
[info] sending 16 results to SumoLogic
And in sumo logic, search for _collector="hawkeye" | json auto
:
The idea is that this project should be super extensible, I want people to write new handlers with ease. Simply create a handler in lib/modules
which exposes the following signature:
- key: A short alphanumeric key for your module
- name: The name of your module
- description: The description of your module
- enabled: True or Fale as to if this module should run by default, or if it needs to be specified with
--module
- function handles(path): A function to decide if this handler should run against the target path
- function run(results, done): The function which is called if handles returns true
The first argument passed is results
, this is where the module should send its results to, it exposes four methods for each 'level' of issue found, critical
, high
, medium
and low
. Those methods expect you to pass something like this:
results.critial('offender', 'description', 'extra', { additional: 'data' });
