It enables RDP/firewall access, creates or enables a privileged RDP account, and disguises installed binaries. - **Trigger:** npm installation on Windows runs \`install --postinstall\`; non-passive CLI use can also trigger first-run setup. - **Impact:** Unauthorized persistent administrative remote access through port 3389 and reduced user visibility of the installed service/account. - **Evidence paths:** package.json, bin/biklimaster.js, lib/bikliwrapper.js - **Review source:** ai\_review - **Reviewed:** 2026-08-17T04:19:44.909Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Privileged RDP backdoor provisioning with hidden administrator account and executable impersonation. - **Attack narrative:** On npm installation, the package runs a postinstall command that elevates through UAC. Its installer deploys bundled executables, creates/starts a service, installs RDP Wrapper, opens inbound TCP and UDP port 3389 rules, enables or creates an administrator-capable RDP user, hides that user from the sign-in screen, and marks folders hidden/system. It also rewrites executable resources to appear as Microsoft svchost.exe. These actions establish a concealed, privileged remote-access foothold without an explicit user command. - **Rationale:** This is concrete malicious install-time behavior: a hidden privileged account, exposed RDP listener, stealth filesystem changes, and Windows-service impersonation. The absence of observed exfiltration endpoints does not reduce the direct backdoor risk. - **Files touched:** package.json, bin/biklimaster.js, lib/bikliwrapper.js, payload/bikli-cli-installer.exe, payload/RDPWInst.exe, C:\\ProgramData\\BikliWrapper\\admin-credentials.json, C:\\Program Files\\Bikli, C:\\Program Files\\RDP Wrapper ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Postinstall invokes the privileged installer automatically., Installer silently installs payloads, provisions a service, enables RDP, creates an administrator, and hides folders., RDP Wrapper creates inbound TCP/UDP firewall rules on port 3389 for every profile., Account setup adds an account to Administrators and Remote Desktop Users, then hides it from the Windows sign-in list., Executable metadata is rewritten to impersonate Microsoft svchost.exe. - **Evidence against:** No HTTP/network-exfiltration endpoint appears in inspected JavaScript., Bundled payload checksums are verified before installation, but this does not mitigate the hostile privileged actions. ## Public findings ### 1.
