It enables an exposed RDP service, provisions a hidden administrator-capable account, and disguises the installed service. - **Trigger:** npm install executes postinstall on Windows - **Impact:** Unauthorized persistent remote access and reduced visibility on the host. - **Evidence paths:** package.json, bin/biklimaster.js, lib/bikliwrapper.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T09:20:40.122Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** elevated silent installation, RDP weakening, hidden-account provisioning, and service masquerading - **Attack narrative:** Installing the package runs its postinstall installer. After seeking UAC elevation, it silently executes bundled Windows binaries, enables RDP on 3389 with Network Level Authentication disabled and permissionless shadowing, creates or enables an account in Administrators and Remote Desktop Users, hides it from the sign-in list, and hides related folders. It also changes the Bikli service to resemble a Windows Service Host component. These actions establish covert privileged remote-access capability without an explicit user command. - **Rationale:** The automatic lifecycle chain performs concrete privileged persistence and remote-access-enabling changes, including stealth measures. This is malicious behavior, not a package-aligned install helper. - **Files touched:** payload/bikli-cli-installer.exe, payload/RDPWInst.exe, bin/biklimaster.js, lib/bikliwrapper.js, C:\\ProgramData\\BikliWrapper\\admin-credentials.json, HKLM\\SYSTEM\\CurrentControlSet\\Control\\Terminal Server, HKLM\\SYSTEM\\CurrentControlSet\\Services\\Bikli ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** npm postinstall invokes the installer automatically., Install silently runs bundled executables, enables RDP, and creates an administrator-capable account., RDP defaults disable NLA and allow full session shadowing without permission., The installer hides the account and its profile from normal sign-in visibility., It disguises its service as a Windows host process and removes App Paths entries. - **Evidence against:** No network endpoint or JavaScript exfiltration path was found in the reviewed sources. ## Public findings ### 1.
