It enables and exposes RDP, weakens its authentication defaults, creates or enables an administrator account, and conceals the installed service and files. - **Trigger:** npm postinstall; no separate user command is required. - **Impact:** Unauthenticated installation can create privileged remote access and evade normal user visibility. - **Evidence paths:** package.json, bin/biklimaster.js, lib/bikliwrapper.js - **Review source:** ai\_review - **Reviewed:** 2026-08-15T09:38:17.105Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Elevated silent RDP backdoor provisioning and service masquerading. - **Attack narrative:** Installing the package triggers an elevated installer. It executes bundled Windows installers, enables RDP on port 3389 with broad inbound firewall rules, disables Network Level Authentication, permits shadowing without consent, and provisions an enabled administrator-level Remote Desktop account. It then hides folders and alters executable/service presentation to resemble a Windows Service Host, creating a concrete stealthy remote-access persistence chain. - **Rationale:** The package performs concrete privileged, stealthy remote-access provisioning automatically at postinstall. The absence of web exfiltration does not mitigate this local backdoor behavior. - **Files touched:** 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:** postinstall launches the privileged installer automatically., Installer silently installs bundled binaries, enables RDP, creates an administrator, and hides folders., RDP defaults disable NLA and enable shadow access without permission., It opens inbound TCP/UDP firewall rules on port 3389 for every profile., It disguises its service/process as a Microsoft-style Service Host., It enables or creates an admin account and adds it to Administrators and Remote Desktop Users. - **Evidence against:** No source-level HTTP/network download or credential-exfiltration code was found., No eval, Function, or dynamic module-loading primitive was found in inspected text sources. ## Public findings ### 1.
