The Hawkeye scanner-cli is a project security, vulnerability and general risk highlighting tool. It is meant to be integrated into your pre-commit hooks and your pipelines.



# Running and configuring the scanner



The Hawkeye scanner-cli assumes that your directory structure is such that it keeps the toolchain's files on top level. Roughly, this is what it boils down to:



* **Node.js** projects have a `package.json` on top level

* **Ruby** projects will have a `Gemfile` on top level

* **Python** projects will have a `requirements.txt` on top level

* **PHP** projects will have a `composer.lock` on top level

* **Java** projects will have a `build` (gradle) or `target` (maven) folder, and include `.java` and `.jar` files

* **Kotlin** projects will have a `build` (gradle) or `target` (maven) folder, and include `.kt` and `.jar` files

* **Scala** projects will have a `target` (sbt with `sbt-native-packager` or `sbt-assembly` plugins) folder, and include 

`.scala` and `.jar` files. Check [this repo](https://github.com/csokol/scala-hawkeyesec-scanner-demo) for a running demo. 

* **Rust** projects will have a `Cargo.toml` on top level



This is not exhaustive as sometimes tools require further files to exist. To understand how the modules decide whether they can handle a project, please check the [How it works](https://github.com/hawkeyesec/scanner-cli#how-it-works) section and the [modules](lib/modules) folder.



#### Docker (recommended)



The docker image is hands-down the easiest way to the scanner. Please note that your project root (e.g. $PWD) needs to be mounted to `/target`.



```bash

docker run --rm -v $PWD:/target hawkeyesec/scanner-cli:latest

```



If you are using the scanner to write a JSON (via the `-j` and `--json` CLI flags and the `json` setting in the `.hawkeyerc`), **make sure that it uses the correct UID and GID** via `docker run -u $(id -u):$(id -g)`. Otherwise this might leave you with undeletable files, e.g. when running in Jenkins.



The docker build is also the recommended way to run the scanner in your CI pipelines. This is an example of running Hawkeye against one of your projects in GoCD:



```xml



  

    

      

        

          

            pull

            hawkeyesec/scanner-cli

            

          

          

            -c

            docker run --rm -v $PWD:/target hawkeyesec/scanner-cli:latest

            

          

        

      

    

  



```

#### npm



You can install and run hawkeye in a Node.js project via



```bash

npm install --save-dev @hawkeyesec/scanner-cli

npx hawkeye scan

```



This method is recommended in a Node.js project, where the other toolchains (e.g. python, ruby) are not required.



With this method, it is also recommended to invoke the scanner in a git pre-commit hook (e.g. via the [pre-commit](https://github.com/observing/pre-commit) package) to fail the commit if issues are found.



#### Configuration Files (recommended)



You can configure the scanner via `.hawkeyerc` and `.hawkeyeignore` files in your project root.



The `.hawkeyerc` file is a JSON file that allows you to configure ...



* the modules to run,

* the writers to use, and

* the failure threshold



```json

{

    "all": true|false,

    "staged": true|false,

    "modules": ["files-ccnumber", "java-owasp", "java-find-secbugs"],

    "sumo": "http://your.sumologic.foobar/collector",

    "http": "http://your.logger.foobar/collector",

    "json": "log/results.json",

    "failOn": "low"|"medium"|"high"|"critical",

    "showCode": true|false

}

```



The `.hawkeyeignore` file is a collection of *regular expressions* matching **paths** and **module error codes** to exclude from the scan, and is equivalent to using the `--exclude` flag. Lines starting with `#` are regarded as comments.



**Please note that any special charaters reserved in regular expressions (-[]{}()*+?.,\^$|#\s) need to be escaped when used as a literal!**



Please also note that the module error codes are usually not shown, since they are not primarily relevant for the user. If you want to exclude a certain false positive, you can display the module error codes with the flag `--show-code` or the `showCode` property in the `.hawkeyerc`.

Use `hawkeye scan` to kick off a scan:



```

> npx hawkeye scan --help

[info] Version: v1.3.0

Usage: hawkeye-scan [options]



Options:

  -a, --all                                       Scan all files, regardless if a git repo is found. Defaults to tracked files in git repositories.

  -t, --target [/path/to/project]                 The location to scan. Defaults to $PWD.

  -f, --fail-on [low|medium|high|critical]        Set the level at which hawkeye returns non-zero status codes. Defaults to low.

  -m, --module [module name]                      Run specific module. Defaults to all applicable modules.

  -e, --exclude [pattern]                         Specify one or more exclusion patterns (eg. test/*). Can be specified multiple times.

  -j, --json [/path/to/file.json]                 Write findings to file.

  -s, --sumo [https://sumologic-http-connector]   Write findings to SumoLogic.

  -H, --http [https://your-site.com/api/results]  Write findings to a given url.

  --show-code                                     Shows the code the module uses for reporting, useful for ignoring certain false positives

  -g, --staged                                    Scan only git-staged files.

  -h, --help                                      output usage information

```



# Results



#### Exit Codes



The scanner-cli responds with the following exit codes:



* Exit code 0 indicates no findings above or equal to the minimum threshold were found.

* Exit code 1 indicates that issues were found above or equal to the minimum threshold.

* Exit code 42 indicates that an unexpected error happened somewhere in the program. This is likely a bug and should not happen. Please check the log output and report a bug.



#### Redirecting the console output



If you wish to redirect the console logger output, the recommended method is latching onto stdout. In this example, we're making use of both JSON and stdout results:



```bash

docker run --rm -v $PWD:/target hawkeyesec/scanner-cli:latest -j hawkeye-results.json -f critical 2>&1 | tee hawkeye-results.txt

```



#### Console output



By default, the scanner outputs its results to the console in tabular form.



#### Sumologic



The results can be sent to a SumoLogic collector of your choice. In this example, we have a collector with a single HTTP source.



```

hawkeye scan --sumo https://collectors.us2.sumologic.com/receiver/v1/http/your-http-collector-url

```



In SumoLogic, search for `_collector="hawkeye" | json auto`:



![SumoLogic](screenshots/sumologic.png)



#### Any HTTP endpoint



Similar to the SumoLogic example, the scanner can send the results to any given HTTP endpoint that accepts POST messages.



```

hawkeye scan --http http://your.logging.foobar/endpoint

```



The results will be sent with `User-Agent: hawkeye`. Similar to the console output, the following `JSON` will be POSTed for each finding:



```json

{

  "module": "files-contents",

  "level": "critical",

  "offender": "testfile3.yml",

  "description": "Private key in file",

  "mitigation": "Check line number: 3"

}

```



# How it works



Hawkeye is designed to be extensible by adding modules and writers.



* Add modules in the [modules](lib/modules) folder.

* Add writers in the [writers](lib/writers) folder.



## Modules



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 `npm outdated` 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.



#### Generic Modules



* **files-ccnumber**: Scans for suspicious file contents that are likely to contain credit card numbers

* **files-contents**: Scans for suspicious file contents that are likely to contain secrets

* **files-entropy**: Scans files for strings with high entropy that are likely to contain passwords. Entropy scanning is disabled by default because of the high number of false positives. It is useful to scan codebases every now and then for keys, in which case please run it please using the `-m files-entropy` switch.

* **files-secrets**: Scans for suspicious filenames that are likely to contain secrets



#### Java / Kotlin / Scala



* **java-find-secbugs**: Finds common security issues in Java code with findsecbugs

* **java-owasp**: Scans Java projects for gradle/maven dependencies with known vulnerabilities with the OWASP dependency checker



#### Node.js



* **node-npmaudit**: Checks node projects for dependencies with known vulnerabilities with [npm audit](https://docs.npmjs.com/cli/audit)

* **node-npmoutdated**: Checks node projects for outdated npm modules with [npm outdated](https://docs.npmjs.com/cli/outdated)

* **node-yarnaudit**: Checks yarn projects for dependencies with known vulnerabilities with [yarn audit](https://yarnpkg.com/lang/en/docs/cli/audit/)

* **node-yarnoutdated**: Checks node projects for outdated yarn modules with [yarn outdated](https://yarnpkg.com/en/docs/cli/outdated)



#### PHP



* **php-security-checker**: Checks whether the composer.lock contains dependencies with known vulnerabilities using security-checker



#### Python



* **python-bandit**: Scans for common security issues in Python code with bandit.

* **python-piprot**: Scans python dependencies for out of date packages with [piprot](https://github.com/sesh/piprot)

* **python-safety**: Checks python dependencies for known security vulnerabilities with the safety tool.



#### Ruby



* **ruby-brakeman**: Statically analyzes Rails code for security issues with Brakeman.

* **ruby-bundler-scan**: Scan for Ruby gems with known vulnerabilities using bundler



#### Rust



* **rust-cargoaudit**: Checks whether the `Cargo.lock` contains dependencies with known vulnerabilities using [cargo audit](https://github.com/RustSec/cargo-audit)
