Unlike custom Windows ISOs, Atlas is more straightforward to audit due to the use of AME Wizard. AME Wizard is controlled by Playbooks, a customizable script-esque system that can perform various tasks.

Playbooks are renamed .zip archives, with the password malte. As they primarily consist of plain text, Playbooks enable transparency, unlike custom Windows ISOs, which have many entry points for malicious activity.

The few binaries in the Playbook are open source in our utilities repository, with the hashes listed here.

Although the GUI is not open source for AME Wizard, AME Wizard’s entire backend (called TrustedUninstaller) is open source under MIT, which contains each action used to run Atlas. The Atlas Playbook is open source under the GPLv3 license.
