It also weakens RDP authentication and creates inbound firewall rules. - **Trigger:** npm postinstall executes \`biklimaster install\` on Windows. - **Impact:** Unauthorised persistent remote administrative access and host concealment. - **Evidence paths:** package.json, bin/biklimaster.js, lib/bikliwrapper.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T09:25:48.752Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Privileged hidden-admin creation, RDP exposure, firewall opening, and executable masquerading. - **Attack narrative:** Installing the package triggers its postinstall command. The install path requests elevation, enables and exposes RDP, opens port 3389 in the firewall, creates or enables a privileged local account, grants it Remote Desktop Users membership, and hides it from the sign-in screen. It also alters executable metadata to resemble Microsoft svchost.exe and hides installation/account folders. - **Rationale:** Concrete unconsented postinstall persistence and remote-access changes establish malware behavior. No exfiltration endpoint is needed to substantiate the local administrative backdoor. - **Files touched:** package.json, bin/biklimaster.js, lib/bikliwrapper.js, payload/bikli-cli-installer.exe, payload/RDPWInst.exe, C:\\ProgramData\\BikliWrapper\\admin-credentials.json, HKLM\\SYSTEM\\CurrentControlSet\\Control\\Terminal Server, HKLM\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon\\SpecialAccounts\\UserList ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Postinstall unconditionally invokes the privileged install workflow., Install enables RDP, creates an administrator account, and hides protected folders., RDP settings disable Network Level Authentication and allow shadowing without permission., The wrapper opens inbound TCP and UDP firewall rules on port 3389., PowerShell creates/enables an admin, grants RDP access, then hides it from sign-in., The package rewrites executable metadata to impersonate Microsoft svchost.exe. - **Evidence against:** No network exfiltration endpoint was found in inspected JavaScript., Bundled payload hashes are verified before installation, but this does not mitigate the install-time backdoor behavior. ## Public findings ### 1.
