## Security analysis

### Published attack-surface review

- **Summary:** On npm postinstall, the package requests elevation, installs native payloads, enables and weakens RDP, creates or enables a hidden administrator account, and conceals its files/service. This is concrete unauthorized remote-access persistence behavior.

- **Trigger:** npm postinstall on Windows

- **Impact:** Creates concealed privileged remote access and exposes inbound RDP on port 3389.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-15T10:33:22.464Z

### AI review details

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

- **Mechanism:** elevated RDP backdoor setup and Windows service impersonation

- **Attack narrative:** Installing the package triggers its postinstall handler. The handler elevates, silently executes bundled installers, applies registry settings that enable insecure RDP and shadowing, opens port 3389, creates or enables an administrator/RDP user, hides it from the sign-in screen, and disguises the service as Windows infrastructure. These actions establish concealed privileged remote access without an explicit user command.

- **Rationale:** The postinstall path performs an automated, stealth-oriented privileged remote-access setup. The behavior is concrete and unrelated to a normal npm dependency installation.

- **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:** npm postinstall automatically invokes the privileged install path., Install creates/enables an administrator-capable RDP account and hides it from the sign-in screen., RDP settings disable Network Level Authentication and allow full shadow access without permission., Installer opens inbound TCP/UDP port 3389 firewall rules., It rewrites executable identity and service metadata to impersonate Windows infrastructure.

- **Evidence against:** No source-level HTTP/network exfiltration endpoint was found., Bundled payloads are hash-checked before execution, but their native behavior was not executed or relied upon.
