This is concrete unconsented host compromise behavior. - **Trigger:** npm installation runs postinstall on Windows. - **Impact:** Remote access is enabled on port 3389 with weakened authentication, hidden privileged accounts, firewall exposure, and disguised service artifacts. - **Evidence paths:** package.json, bin/biklimaster.js, lib/bikliwrapper.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T09:21:02.281Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** privileged RDP backdoor setup with stealth and persistence changes - **Attack narrative:** On installation, the package requests elevation, silently runs bundled installers, enables and persists Remote Desktop, creates inbound firewall rules, disables Network Level Authentication, and grants an enabled account membership in Administrators and Remote Desktop Users. It hides that account from the Windows sign-in screen, hides related folders, removes history artifacts, and renames the service to resemble Windows infrastructure. These actions establish stealthy privileged remote access without an explicit user command. - **Rationale:** This package performs a malicious install-time Windows backdoor chain rather than a package-aligned setup. The absence of outbound JavaScript networking does not reduce the concrete remote-access and stealth impact. - **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 automatically invokes the privileged install path., Install enables RDP, opens firewall rules, and disables Network Level Authentication., Install creates/enables an administrator-capable RDP account and hides it from the sign-in screen., Code disguises the installed service as Windows infrastructure and clears execution-history artifacts., Bundled Windows executables are silently executed during installation. - **Evidence against:** No HTTP/network client or exfiltration code was found in the JavaScript source., Payload hashes are checked before installation, but this only verifies the package's own bundled binaries. ## Public findings ### 1.
