It creates or enables a hidden administrator, weakens RDP security, opens port 3389, and conceals its service. - **Trigger:** npm install (postinstall) on Windows - **Impact:** Unconsented remote-access exposure and persistent privileged account/service concealment. - **Evidence paths:** package.json, bin/biklimaster.js, lib/bikliwrapper.js, config.json - **Review source:** ai\_review - **Reviewed:** 2026-08-16T09:26:07.957Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** privileged RDP backdoor setup and stealth persistence - **Attack narrative:** On npm postinstall, the package requests elevation and silently installs bundled executables. It configures RDP for inbound port 3389 with NLA disabled and consent-free session shadowing, then enables or creates an administrator-level RDP user and hides it from the sign-in list. It also disguises binaries and service metadata as Microsoft/svchost, hides protected folders, and removes application-history traces. - **Rationale:** This is a concrete, unconsented install-time remote-access and stealth-persistence chain, not a package-aligned installer. Source contains no compensating user-command gate beyond the elevation prompt. - **Files touched:** payload/bikli-cli-installer.exe, payload/RDPWInst.exe, %ProgramData%\\BikliWrapper\\admin-credentials.json, %ProgramFiles%\\Bikli\\BikliService.exe, 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:** postinstall automatically invokes the privileged installer., Install creates an RDP-capable administrator account, hides folders, and clears history., Wrapper disables NLA, permits shadowing without consent, and opens inbound RDP 3389., Code disguises its executable as Microsoft svchost and rewrites service metadata., Published config contains nonempty administrative credentials. - **Evidence against:** No source-visible HTTP endpoint or credential exfiltration was found., Payload hashes are checked before use. ## Public findings ### 1.
