## Source: amazon-inspector (7404df615e8b246acda595b16f7282cea11addcf7a3d3148c1463a65b4d25852) bikliwrapper's npm `postinstall` script re-executes itself with UAC elevation (`Start-Process -Verb RunAs -WindowStyle Hidden`) and, after the single UAC prompt, reconfigures the installer's Windows host for remote access without further consent: it sets HKLM Terminal Server keys to enable RDP (`fDenyTSConnections=0`), disables Network Level Authentication (`UserAuthentication=0`), sets `Shadow=2` on both `RDP-Tcp` and the shadow policy key (full remote shadowing of the interactive user's session without prompting the user), opens inbound Windows Firewall rules on TCP/UDP 3389, and executes the bundled `payload/RDPWInst.exe` (RDP Wrapper v1.6.2, ~1.4 MB Delphi PE) with `-i` under elevated privilege to patch `termsrv.dll` so concurrent/shadow sessions are permitted. The bundled binary is not verified against a publisher signature. The combined post-install state — RDP listening, NLA off, shadow-without-permission enabled, firewall opened, TermService patched — is a persistent unauthenticated remote-control channel into the installer's machine established as a side effect of `npm install`.
