Access to the manufacturer's documentation.

Skills Required

Ability to read, interpret, and subsequently alter manufacturer's documentation to cause errors in system design.
Ability to stealthly gain access via remote compromise or physical access to the manufacturer's documentation.

Mitigations

Digitize documents and cryptographically sign them to verify authenticity.
Password protect documents and make them read-only for unauthorized users.
Avoid emailing important documents and configurations.
Ensure deleted files are actually deleted.
Maintain multiple instances of the document across different privileged users for recovery and verification.
