## Verdict summary
**Blocked & quarantined** — An attacker can receive sensitive environment values and obtain a shell on the installing machine.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Install Hook Abuse
- **Selected version:** 0.0.1
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

Installation automatically executes code that harvests likely secrets, transmits them to a configured remote host, and starts a reverse shell. This is a concrete install-time compromise path.

## Security analysis

### Published attack-surface review

- **Summary:** Installation automatically executes code that harvests likely secrets, transmits them to a configured remote host, and starts a reverse shell. This is a concrete install-time compromise path.

- **Trigger:** Installing the package runs its postinstall hook.

- **Impact:** An attacker can receive sensitive environment values and obtain a shell on the installing machine.

- **Evidence paths:** package.json, index.js, servers.json

- **Review source:** ai\_review

- **Reviewed:** 2026-09-03T22:53:49.772Z

### AI review details

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

- **Mechanism:** Environment-secret exfiltration and netcat reverse-shell execution.

- **Attack narrative:** npm runs the package postinstall hook, which executes index.js. The script loads a bundled remote server address, selects likely secret-bearing environment variables, and writes them to a TCP connection. It then invokes netcat with the -e option to connect a shell to the same host and port. The package metadata also identifies it as a nestjs typosquat.

- **Rationale:** This package contains a complete automatic install-time chain for secret exfiltration and remote shell access. The behavior is malicious and requires blocking.

- **Files touched:** index.js, servers.json

- **Network endpoints:** 84.32.22.44:9999

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** The postinstall hook automatically runs index.js during package installation., The entry script collects environment variables whose names begin with SECRET, API, TOKEN, or KEY., The bundled server configuration names 84.32.22.44 on port 9999., The script sends collected values over a network socket and invokes netcat with a shell., The manifest explicitly describes the package as a typosquat of nestjs.

## Public findings

- **Path:** index.js
- **Public source:** [View source](<https://unpkg.com/2nestjs@0.0.1/index.js>)

A package entrypoint or install-time lifecycle script reaches a source file with blocking dangerous behavior.

...
L7: try {
L8: servers = JSON.parse(fs.readFileSync('./servers.json'));
