Debug Privilege determines which users can attach to or open any process, even those they do not own. Developers who are debugging their own applications do not need to be assigned this user right. Developers who are debugging new system components need this user right. This user right provides access to sensitive and critical operating-system components.
Security Risk: The Debug programs user right can be exploited to capture sensitive computer information from system memory or to access and modify kernel or application structures. Some attack tools exploit this user right to extract hashed passwords and other private security information or to insert rootkit code. By default, the Debug programs user right is assigned only to administrators, which helps mitigate risk from this vulnerability.
This video explains how you can disable or stop the Debug Privilege on Windows.
