It enables and exposes RDP, weakens authentication, creates or enables a privileged hidden account, and disguises a service. - **Trigger:** npm install runs the postinstall hook on Windows; elevation is requested. - **Impact:** Remote access exposure and concealed privileged persistence on the installed host. - **Evidence paths:** package.json, bin/biklimaster.js, lib/bikliwrapper.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T09:26:13.581Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Elevated PowerShell, registry, firewall, service, and local-account mutation. - **Attack narrative:** Installing the package executes its install command through postinstall. The command requests administrator elevation, installs bundled executables, enables RDP on port 3389, disables Network Level Authentication, permits shadow access without permission, and adds inbound firewall rules. It enables the built-in Administrator or creates a local administrator, adds it to Administrators and Remote Desktop Users, and hides it from the sign-in screen. It also changes service metadata to resemble Windows infrastructure and hides installed folders. - **Rationale:** This is concrete, automatic install-time host compromise behavior, not an inert installer primitive. The lack of observed exfiltration does not mitigate the concealed privileged remote-access chain. - **Files touched:** package.json, bin/biklimaster.js, lib/bikliwrapper.js, payload/bikli-cli-installer.exe, payload/RDPWInst.exe, payload/rdpwrap.ini ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** npm postinstall automatically invokes privileged install logic., Install enables RDP and creates a privileged account., RDP settings disable NLA and permit shadow access without permission., It opens inbound TCP/UDP firewall rules on port 3389., Account logic enables/creates an administrator and hides it from sign-in., It disguises its service as a Windows host and hides protected folders. - **Evidence against:** No source-level HTTP/network client or remote payload download was found., Payload checksums are verified before installation. ## Public findings ### 1.
