ADOKit: Azure DevOps Services Attack Toolkit

ADOKit

Azure DevOps Services Attack Toolkit – ADOKit is a toolkit that can be used to attack Azure DevOps Services by taking advantage of the available REST API. The tool allows the user to specify an attack module, along with specifying valid credentials (API key or stolen authentication cookie) for the respective Azure DevOps Services instance. The attack modules supported include reconnaissance, privilege escalation, and persistence. ADOKit was built in a modular approach so that new modules can be added in the future by the information security community.

Full details on the techniques used by ADOKit are in the X-Force Red whitepaper.
