It creates or enables a hidden privileged Windows account and exposes RDP. - **Trigger:** npm postinstall - **Impact:** Unauthorised privileged local access and remotely reachable RDP service with weakened authentication. - **Evidence paths:** package.json, bin/biklimaster.js, lib/bikliwrapper.js - **Review source:** ai\_review - **Reviewed:** 2026-08-14T10:39:31.387Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** elevated RDP backdoor configuration and hidden administrator creation - **Attack narrative:** Installing the package runs its installer automatically. After UAC elevation it installs bundled executables, enables/configures RDP, weakens RDP authentication and shadowing, creates or enables a privileged local account, grants Remote Desktop Users membership, hides the account from the sign-in screen, and opens inbound port 3389. The package also hides related folders and stores generated credentials locally. - **Rationale:** This is concrete, unconsented install-time privileged system mutation that creates a concealed remote-access path. The absence of observed exfiltration does not mitigate the backdoor behavior. - **Files touched:** package.json, bin/biklimaster.js, lib/bikliwrapper.js, payload/bikli-cli-installer.exe, payload/RDPWInst.exe, payload/rdpwrap.ini, %ProgramData%\\BikliWrapper\\admin-credentials.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall automatically invokes the installer., Install creates/enables an administrator and grants Remote Desktop access., It disables RDP protections and opens inbound TCP/UDP 3389., It hides installed folders and administrator-like user profiles. - **Evidence against:** No outbound network endpoint or exfiltration API appears in the reviewed JavaScript., Payload hashes are checked before execution. ## Public findings ### 1.
