It creates or enables a hidden administrator, weakens RDP authentication, and opens port 3389. - **Trigger:** npm installation on Windows runs postinstall. - **Impact:** Unauthorized remote access and persistent privileged access on the installed host. - **Evidence paths:** package.json, bin/biklimaster.js, lib/bikliwrapper.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T09:24:49.377Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Elevated hidden-account creation, RDP weakening, firewall exposure, and service disguise. - **Attack narrative:** On npm installation, the package invokes an elevated installer. It installs bundled Windows binaries, configures Remote Desktop with Network Level Authentication disabled and permissionless shadowing, opens inbound RDP firewall rules, and creates or enables a hidden administrator account with Remote Desktop Users membership. It then disguises the service as a Windows infrastructure component and hides related folders, producing a stealthy persistent remote-access path. - **Rationale:** This is concrete install-time privilege escalation, stealth, and remote-access enablement rather than a legitimate package-aligned installer. The absence of a web endpoint does not mitigate the local backdoor behavior. - **Files touched:** bin/biklimaster.js, lib/bikliwrapper.js, payload/bikli-cli-installer.exe, payload/RDPWInst.exe, payload/rdpwrap.ini, config.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall invokes the privileged installer automatically., Install enables/creates a hidden local administrator and adds it to RDP users., RDP configuration disables NLA and permits shadowing without permission., Installer opens inbound TCP/UDP 3389 firewall rules., It disguises the installed service as a Windows infrastructure host and hides protected folders. - **Evidence against:** No source-level web or exfiltration endpoint was found. ## Public findings ### 1.
