Gitleaks is a free and open source tool for finding secrets in git repositories. These secrets could be passwords, API keys, tokens, private keys or suspicious file names or file extensions like id_rsa, .pem, htpasswd. Furthermore gitleaks can scan your whole repository's history with all commits up to the initial one.

The gitleaks scanner can be deployed with helm:
helm upgrade --install gitleaks secureCodeBox/gitleaks
For a complete overview of the configuration options checkout the Gitleaks documentation.
The only mandatory parameters are:
-r: The link to the repository you want to scan.
--access-token: Only for non-public repositories.
--password: Only for non-public repositories.
--config: The ruleset you want to use.
Do not override the option
--report. It is already configured for automatic findings parsing.
At this point we provide three rulesets which you can pass to the
/home/config_all.toml: Includes every rule.
/home/config_filenames_only.toml: Gitleaks scans only file names and extensions.
/home/config_no_generics.toml: No generic rules like searching for the word password. With this option you won't find something like password = Ej2ifDk2jfeo2 but it will reduce resulting false positives.
Other useful options are:
--commit-since: Scan commits more recent than a specific date. Ex: '2006-01-02' or '2006-01-02T15:04:05-0700' format.
--commit-until: Scan commits older than a specific date. Ex: '2006-01-02' or '2006-01-02T15:04:05-0700' format.
--repo-config: Load config from target repo. Config file must be ".gitleaks.toml" or "gitleaks.toml".
It is not an easy task to classify the severity of the scans because we can't tell for sure if the finding is e.g. a real or a testing password. Another issue is that the rate of false positives for generic rules can be very high. Therefore, we tried to classify the severity of the finding by looking at the accuracy of the rule which detected it. Rules for AWS secrets or Artifactory tokens are very precise, so they get a high severity. Generic rules on the other hand get a low severity because the often produce false positives.
Please keep in mind that findings with a low severity can be actually very critical.

An Example for scanning all history of the multi juicer project on GitHub:
apiVersion: "execution.securecodebox.io/v1"kind: Scanmetadata:name: "scan-multi-juicer-example"spec:scanType: "gitleaks"parameters:- "-r"- "https://github.com/iteratec/multi-juicer"- "--config"- "/home/config_all.toml"
Another example for how to scan a private GitLab repository:
apiVersion: "execution.securecodebox.io/v1"kind: Scanmetadata:name: "scan-private-repository-example"spec:scanType: "gitleaks"parameters:- "-r"- "https://gitlab.yourcompany.com/group/project"- "--access-token"- "<YOUR-GITLAB-TOKEN>"- "--config"- "/home/config_filenames_only.toml"- "--commit-since"- "2020-04-20"
