Machine Synopsis
Bitlab is a medium difficulty Linux machine running a Gitlab server. The website is found to contain a bookmark, which can autofill credentials for the Gitlab login. After logging in, the user's developer access can be used to write to a repository and deploy a backdoor with the help of git hooks. The PostgreSQL server running locally is found to contain the user's password, which is used to gain SSH access. The user's home folder contains Windows binary, which is analyzed to obtain the root password.
