## Verdict summary
**Blocked & quarantined** — Unconsented disclosure of installation-host metadata to a third party.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Block by default
- **Public report status:** Published
- **Threat category:** Data Exfiltration
- **Selected version:** 3.0.1
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block.

AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

Direct inspection confirms concrete install-time network exfiltration of host metadata, with no package source implementation present. This is malicious supply-chain behavior.

## Security analysis

### Published attack-surface review

- **Summary:** Installing the package automatically sends host-identifying metadata to a third-party webhook. No source files besides the manifest are present.

- **Trigger:** npm install, before package installation completes

- **Impact:** Unconsented disclosure of installation-host metadata to a third party.

- **Evidence paths:** package.json

- **Review source:** ai\_review

- **Reviewed:** 2026-07-15T10:20:53.361Z

### AI review details

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

- **Mechanism:** preinstall curl POST exfiltrates hostname and timestamp

- **Attack narrative:** \`package.json\` executes a \`preinstall\` command automatically when npm installs this package. The command POSTs to a third-party webhook URL and includes \`$(hostname)\` plus the current timestamp as a query parameter, creating unconsented install-host telemetry. The manifest is the only package file and its declared runtime entrypoint does not exist, so the package provides no apparent legitimate implementation that would justify the lifecycle network call.

- **Rationale:** Direct inspection confirms concrete install-time network exfiltration of host metadata, with no package source implementation present. This is malicious supply-chain behavior.

- **Files touched:** package.json

- **Network endpoints:** https://webhook.site/54919426-084d-4288-8f80-e36ae5c76e32

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** \`package.json\` defines a \`preinstall\` lifecycle hook., The hook runs \`curl -X POST\` to \`webhook.site\` during installation., It embeds the installing host's hostname and a timestamp in the request URL., The package description explicitly says “Softwaer supply chain attack vector”., Declared \`index.js\` entrypoint is absent; package contains only \`package.json\`.

## Affected versions and remediation
