RDP Wrapper is an open-source, dual-use Windows tool used to enable and extend Remote Desktop Protocol functionality, including allowing concurrent or unlimited RDP sessions by modifying how Terminal Services operates. In the provided reporting, it is referenced both as a legitimate/open-source utility and as a tool used or customized by threat actors. One observed deployment chain involved a component named RDPWrapper.exe that extracted embedded DLLs and tools to C:\Program Files\RDP Wrapper, added a Microsoft Defender exclusion for that directory, took ownership of termsrv.dll using takeown and icacls, and patched termsrv.dll to remove session limits. Reporting on the CTRL toolkit states that its stager downloaded RDPWrapper.exe from hui228[.]ru:82/hosted/, and that this component patched termsrv.dll, installed RDP Wrapper, added Defender exclusions, and configured Windows for unlimited concurrent RDP sessions to support persistent remote access and RDP hijacking. A separate joint advisory on DPRK-linked Andariel activity lists RDP Wrapper among open-source and dual-use tools used or customized by the actors. High-confidence associations in the content therefore tie RDP Wrapper to post-compromise remote access enablement on Windows systems, especially to facilitate hands-on-keyboard access via RDP.
