It also disguises the installed process as a Windows service and clears traces. - **Trigger:** npm install executes postinstall on Windows. - **Impact:** Unauthorised administrator-level remote access and reduced visibility on the host. - **Evidence paths:** package.json, bin/biklimaster.js, lib/bikliwrapper.js, config.json - **Review source:** ai\_review - **Reviewed:** 2026-08-16T09:21:01.186Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** privileged hidden remote-access provisioning and stealth persistence. - **Attack narrative:** Installing the package runs its postinstall hook. The hook elevates through UAC, installs bundled executables, weakens and opens RDP, creates or enables an administrator-capable account using package configuration, hides associated folders/accounts, disguises the executable as a Microsoft service, and clears application-history traces. These actions are automatic and establish covert remote-access capability. - **Rationale:** This is concrete install-time hostile behavior, not merely an administrative installer: it creates concealed privileged remote access and employs impersonation and trace removal. Absence of observed network exfiltration does not reduce the severity of the resulting access channel. - **Files touched:** package.json, bin/biklimaster.js, lib/bikliwrapper.js, config.json, payload/bikli-cli-installer.exe, payload/RDPWInst.exe ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall automatically invokes privileged install code., Install enables/creates an administrator account, adds RDP access, and hides it., RDP defaults disable NLA, allow shadowing without permission, and open port 3389., Code disguises executables as Microsoft svchost and removes Bikli history., Package config supplies a hardcoded administrator password. - **Evidence against:** No network endpoint or exfiltration code was found in inspected JavaScript., Bundled payload hashes are checked before installation. ## Public findings ### 1.
