Attacker's goals
I have identified the following possible targets for an attacker:
- Leak source code (or accidentally publish the code on some Internet resource by careless developer);
- Submit malicious code;
- Modify release tag to point vulnerable commit - the application is not being built from the expected commit (from the attacker's commit);
- Delete malicious code from history (i.e. force push or delete branch) - evidence clearing;
- Remove a repository - disrupt the development process;
- RCE on ADO Server or Build agent -> Lateral movement and other malicious activity -> Submit malicious code.
The attacker's targets in the attack tree are indicated by a purple rounded rectangle.
