Windows Provisioning Packages: A Hidden Automation Mechanism and Potential Attack Vector
The article examines Windows provisioning packages (.ppkg) as a mechanism for automated device configuration, enabling system settings, application installation, and command execution without manual intervention. Such packages can be applied during the initial setup phase (OOBE) or on a running system and may include user accounts, network configurations, and security policies.
Particular attention is given to the internal mechanics: instructions are executed via the provisioning engine (provtool.exe) with SYSTEM privileges, including scheduled task execution and automatic configuration deployment. This turns a .ppkg from a simple configuration file into an executable workflow with high privileges, which, if misused or compromised, can lead to privilege escalation and covert execution of arbitrary actions.
