It opens RDP on port 3389 with weakened authentication, creates or enables a privileged hidden account, and disguises a persistent service. - **Trigger:** npm installation on Windows via postinstall; fallback first CLI invocation can also run installation. - **Impact:** Unauthorised remote access, privileged account persistence, reduced visibility, and weakened host security. - **Evidence paths:** package.json, bin/biklimaster.js, lib/bikliwrapper.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T09:21:06.966Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** elevated RDP backdoor setup and service masquerading - **Attack narrative:** Installing the package triggers its postinstall installer. On Windows it asks for elevation, executes bundled installers, enables and exposes RDP on 3389 while disabling NLA and permitting shadow access without consent. It enables or creates an administrator-level Remote Desktop account, hides it from the sign-in screen, stores its credentials, and masks the installed Bikli service as a Windows infrastructure service while removing discoverability entries. These are concrete persistence and remote-access actions, not a normal package installation. - **Rationale:** The package performs an unconsented elevated postinstall chain that weakens RDP security, creates hidden privileged access, and disguises persistence. No exfiltration endpoint is needed for this concrete backdoor-like behavior. - **Files touched:** package.json, 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 invokes the installer automatically., Install elevates, installs bundled binaries, enables RDP, creates an administrator, and hides folders., RDP defaults disable NLA and allow shadowing without consent., It opens inbound TCP/UDP 3389 firewall rules., It enables/adds a local account to Administrators and Remote Desktop Users, then hides it from sign-in., It disguises the Bikli service as Windows infrastructure and removes its App Paths entries. - **Evidence against:** No source-level HTTP client, remote URL, or credential-exfiltration path was found., Payload hashes are checked before installation, but that does not mitigate the harmful local changes. ## Public findings ### 1.
