Although the Registry is common to several Windows operating systems, there are some differences among them. ini files that are used in Windows 3.x and MS-DOS configuration files, such as the Autoexec.bat and Config.sys. The Registry replaces most of the text-based. The Registry contains information that Windows continually references during operation, such as profiles for each user, the applications installed on the computer and the types of documents that each can create, property sheet settings for folders and application icons, what hardware exists on the system, and the ports that are being used. REGISTRYĪ central hierarchical database used in Microsoft Windows 98, Windows CE, Windows NT, and Windows 2000 used to store information that is necessary to configure the system for one or more users, applications and hardware devices.
Therefore, UAC is the first wall we have to cross if we want to deploy some unusual things on the computer. Starting with Windows Vista, when a process requires higher permissions, or using run as, the system will display a UAC menu, if Yes, the process will use the token with administrator rights and continue. UAC uses the token mechanism, when the user logs in, the system will provide two tokens to the user, one token determines the rights to use all the rights of normal users, the remaining token will determine the rights of the user administration. UAC was developed by Microsoft to limit the privileges of users on the Administrators Group, that is, only use administrative rights when necessary. When a standard user attempts to run an app that requires an administrator access token, UAC requires that the user provide valid administrator credentials. UAC helps mitigate the impact of malware.Īpps with lower integrity levels cannot modify data in applications with higher integrity levels. User Account Control (UAC) is a fundamental component of Microsoft’s overall security vision. The following diagram details the UAC architecture. Today, we are going to try to bypass UAC via registry hijacking. In the previous post, we know how to use Dll Hijacking to load our “desire code” into memory with WPF Applications on Windows 10.
