## Security analysis

### Published attack-surface review

- **Summary:** On npm postinstall, this Windows-only package elevates and silently installs bundled executables. It enables and exposes RDP, establishes a privileged hidden account, and disguises a service as Windows infrastructure.

- **Trigger:** npm postinstall for sbironman@1.0.0 on Windows

- **Impact:** Unauthorized persistent remote access and reduced visibility on the host.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-15T09:38:02.935Z

### AI review details

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

- **Mechanism:** elevated install-time RDP backdoor setup with stealth service masquerading

- **Attack narrative:** Installing the package triggers its postinstall command. The installer requests elevation, executes bundled Windows payloads, enables RDP with weakened authentication and unattended shadowing, opens port 3389, and creates or enables an administrator-capable account. It then hides the account and related folders and modifies executable/service metadata to resemble Microsoft svchost infrastructure. These actions form a concrete stealthy remote-access persistence chain.

- **Rationale:** Source directly confirms unconsented install-time creation of a concealed, privileged RDP access path and service masquerading. Absence of JavaScript network exfiltration does not mitigate this concrete local compromise chain.

- **Files touched:** bin/biklimaster.js, lib/bikliwrapper.js, config.json, 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 the privileged install command., Install invokes bundled payloads, RDP setup, account creation, and folder hiding., RDP defaults disable NLA and permit full shadow access without permission., Creates inbound TCP/UDP firewall rules on port 3389 for every profile., Enables or creates a local account, adds it to privileged groups, and hides it from sign-in., Rebrands an executable as Microsoft/svchost and rewrites its service metadata.

- **Evidence against:** No HTTP, DNS, socket, or download code was found in the JavaScript sources., No credential or data exfiltration endpoint is present; the harmful behavior is local install-time system mutation.
