GitHub

github edition enterprise + open source the github integration scans repositories, gists, issues, and pull requests on github cloud or github enterprise server for credentials and other sensitive data for push events as they occur, see the github real time docid\ yesn9axi56x8yu47iqbkr source instead dependencies (self hosted deployment only) this setup requires specific tools for effective operation git is essential for repository management, while rpm2cpio, binutils, and cpio are necessary for extracting files from rpm and deb package formats git for cloning repositories rpm2cpio to extract content from rpm packages binutils includes the "ar" tool, crucial for extracting contents from deb files cpio a versatile file archiver utility, compatible with various archive formats including rpm and deb installing dependencies on ubuntu to install these dependencies on an ubuntu system, follow these steps open a terminal update your package lists to ensure you get the latest version available $ sudo apt update install the required packages sudo apt install git rpm2cpio binutils cpio configuration the github integration can be configured in trufflehog under integrations , or via a local configuration file (below) web configuration configure this integration from the integrations page in trufflehog you'll need either a github personal access token (classic), or a github app installed on the accounts or organizations you want to scan once on the integrations page, click on add integration in the top right corner click on the source tile, then click on the github tile you can choose from the following public and private sources note that the rest of the “web configuration” instructions will follow this path public source requires no authentication you can list individual repositories to scan or add organization(s) if adding organizations, then the source integration will scan all discoverable public repositories in those organizations github action links to documentation on how to use trufflehog within a github action after clicking on public and private sources , click on hosted scanner doing so will redirect you to a github verification page, or if already signed in, a github app creation page after github app creation you’ll be redirected back to trufflehog with this view here you’ll be able to set the duration between scans and decide on the inclusion or exclusion of certain objects in the scan note that if “repository to include” and “repository to exclude” are left blank, then trufflehog will scan whatever the app has access to within github more information is available in the next step after making your selections, click “save” clicking “save” redirects you to the github organization selection screen if you have multiple organizations, choose the organization you’d like to add that application to we will cover installing the app on multiple organizations in the next few steps after choosing your organization choose “all repositories” or “only select repositories” and then click “install” to add the application to multiple organizations navigate to your github apps page (https //github com/settings/apps), find the app you created in the list, and click “edit” click “install app” in the left navigation bar click “install” on each organization you’d like to add the application to note you will be required to choose “all repositories” or “only select repositories” for each organization like you did in step #7 local configuration local configuration supports two authentication methods bearer token — uses a github personal access token (classic) github app — uses a registered github app, which can scan repositories across any account or organization where the app is installed bearer token create a classic personal access token with the following scopes repo — read access to repository contents gist — read access to gists read\ org — read organization membership fine grained tokens are not

single github app can scan repositories across multiple accounts or organizations as long as the app is installed on each of them each account requires a separate trufflehog source configuration using the same appid paired with that account's installationid and a unique name setup is a three step process register the app, install it, and configure trufflehog step 1 register a github app sign in to github and navigate to your account settings for an app owned by a personal account click your profile photo, then settings for an app owned by an organization click your profile photo, then your organizations , then settings next to the organization in the left sidebar, click developer settings click github apps , then new github app fill in the app details field value github app name any descriptive name (e g , trufflehog scanner app) homepage url your trufflehog instance url https //\<your org> c1 prod trufflehog org webhook leave active selected webhook url https //\<your org> c1 prod trufflehog org/sources/github/webhook configure the following permissions if you change permissions after the app is installed, the installation must be re authorized for changes to take effect permission group permission access repository contents read only repository metadata (mandatory) read only repository webhooks read and write repository issues read only repository pull requests read only organization members read only account gists read only under where can this github app be installed? , choose only on this account to restrict installation to the creating account any account to allow installation on any user or organization click create github app generate a private key from settings > developer settings > github apps > \[your app] > private keys > generate a private key a single private key works across all installations of the app note the app id shown on the app's about page — you'll need it for configuration step 2 install the github app from developer settings > github apps , select your app in the left panel under general , click install app click install next to the account where you want to install the app select all repositories , review the permissions, and click install find the installation id by navigating to settings > integrations > applications > installed github apps , clicking the gear icon next to your app, and copying the trailing number from the url https //github com/settings/installations/\<installationid> a new installation id is generated each time the app is installed on a different account step 3 configure trufflehog sources \
