## Security analysis

### Published attack-surface review

- **Summary:** npm postinstall requests elevation, installs bundled payloads, enables insecure Remote Desktop access, and creates a concealed privileged account. It also disguises the installed payload as a Windows service.

- **Trigger:** npm postinstall on Windows

- **Impact:** Creates unauthorized remote-access and stealth-persistence capability.

- **Evidence paths:** package.json, bin/biklimaster.js, lib/bikliwrapper.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-16T09:20:37.462Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** elevated silent install, RDP/firewall reconfiguration, concealed administrator persistence

- **Attack narrative:** Installing the package runs its postinstall installer. After requesting elevation, it silently installs bundled executables, enables RDP on port 3389 with NLA disabled, creates firewall rules, enables or creates an administrator-level RDP account, hides that account, and disguises the payload as a Microsoft service. This is an unconsented install-time remote-access and persistence chain.

- **Rationale:** The lifecycle hook causes these privileged, security-weakening changes without an explicit user command. The absence of observed exfiltration does not mitigate the concrete backdoor-like install behavior.

- **Files touched:** 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 automatically invokes installation., Install silently runs bundled executables and then configures RDP., RDP settings disable NLA and permit shadowing without consent., Installer creates inbound TCP/UDP firewall rules for RDP port 3389., Install enables or creates an administrator/RDP user and hides it from sign-in., Code disguises its payload as Microsoft Service Host and hides protected folders.

- **Evidence against:** No outbound network client, URL, or credential-exfiltration code was found in inspected JS sources., Payload hashes are verified before installation.
