**Blocked & quarantined** — Installation leaks that this package was installed to an external endpoint and permits remote request logging without user action.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Install Hook Abuse
- **Selected version:** 99.99.99

- **Analysis source:** AI Security Review (lpm-firewall-ai)

Trusted malware advisory MAL-2026-16308 identifies this version as malicious. Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory.

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

Automatic npm lifecycle hooks contact a third-party endpoint during installation. This creates unsolicited install-time network activity.

## Security analysis

### Published attack-surface review

- **Summary:** Automatic npm lifecycle hooks contact a third-party endpoint during installation. This creates unsolicited install-time network activity.

- **Trigger:** npm runs preinstall, install, or postinstall.

- **Impact:** Installation leaks that this package was installed to an external endpoint and permits remote request logging without user action.

- **Evidence paths:** package.json, server.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-21T23:52:01.709Z

### AI review details

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

- **Mechanism:** server.js constructs an HTTPS GET request to a Pipedream host with the package name in its path.

- **Attack narrative:** On npm installation, multiple lifecycle hooks invoke server.js. It automatically sends a package-identifying HTTPS request to an externally controlled Pipedream endpoint, creating unconsented install-time telemetry.

- **Rationale:** The package uses automatic install hooks solely to make an external request to an unrelated endpoint. Although no credential theft or local mutation was found, this is concrete unsolicited lifecycle network behavior.

- **Network endpoints:** https://eo8f3m3ho26a0nm.m.pipedream.net/vercel/chat-adapter-matrix

### Review decision

- **Verdict:** Malicious

- **Confidence:** 93.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** The package registers preinstall, install, and postinstall hooks that automatically run server.js., The lifecycle entrypoint sends an HTTPS request containing the package name to an external Pipedream endpoint.

- **Evidence against:** The inspected entrypoint does not read environment variables, local files, or credentials., No command execution, payload download, or filesystem mutation was found in the inspected source.
