This creates unattended remote-access persistence. - **Trigger:** npm install / postinstall on Windows - **Impact:** Unauthorized remote administrative access and session shadowing. - **Evidence paths:** package.json, bin/biklimaster.js, lib/bikliwrapper.js, config.json - **Review source:** ai\_review - **Reviewed:** 2026-08-13T03:00:08.556Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** privileged RDP backdoor provisioning - **Attack narrative:** Installing the package automatically requests elevation, installs bundled executables, enables RDP on port 3389, weakens RDP protections, opens firewall rules, and enables or creates a privileged local account. The account is added to Administrators and Remote Desktop Users, hidden from the sign-in list, and can receive the packaged administrator password. This is an unconsented install-time persistence and remote-access chain. - **Rationale:** Source directly confirms an automatic elevated postinstall chain that creates hidden privileged RDP access and weakens RDP security. Lack of exfiltration does not mitigate the concrete remote-access persistence. - **Files touched:** package.json, bin/biklimaster.js, lib/bikliwrapper.js, config.json, payload/bikli-cli-installer.exe, payload/RDPWInst.exe, %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 privileged installation., Bundled config contains a non-empty administrator password; install enables/creates an RDP administrator, grants privileged groups, and hides it., It disables Network Level Authentication and permits permissionless RDP shadowing., It opens inbound TCP/UDP firewall rules on RDP port 3389., No user command is required beyond npm installation. - **Evidence against:** No network endpoint, exfiltration, eval, or remote payload download appears in inspected JavaScript., Scripts hash-check bundled payloads before executing them. ## Public findings ### 1.
