## Verdict summary
**Blocked & quarantined** — Unconsented disclosure of host and account-identifying metadata.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Data Exfiltration
- **Selected version:** 1.0.0
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

Installation automatically collects the host name and current user, then transmits them off-host. This is unrelated to the advertised string utilities.

## Security analysis

### Published attack-surface review

- **Summary:** Installation automatically collects the host name and current user, then transmits them off-host. This is unrelated to the advertised string utilities.

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

- **Impact:** Unconsented disclosure of host and account-identifying metadata.

- **Evidence paths:** package.json, postinstall.js, README.txt, index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-07-28T18:14:28.708Z

### AI review details

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

- **Mechanism:** shell command exfiltrates hostname and whoami via curl

- **Attack narrative:** On npm installation, package.json launches postinstall.js. That script executes curl and interpolates the installing machine's hostname and current username into a request to an external OAST endpoint, causing unconsented metadata exfiltration.

- **Rationale:** Direct source inspection confirms an install-time shell command that collects and exfiltrates host/user identifiers to a third party. The runtime utility entrypoint does not justify this behavior.

- **Files touched:** package.json, postinstall.js

- **Network endpoints:** http://pzs5w7ntzhsnepwk564lyfdci3oucl0a.oastify.com/probe?h=\<hostname\>&u=\<whoami\>

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json runs postinstall.js automatically on install., postinstall.js invokes child\_process.exec., It runs curl with hostname and whoami substituted into the URL., Collected host/user data is sent to an OAST endpoint., README.txt documents the same out-of-band probe.

- **Evidence against:** index.js only exports basic string utilities., No legitimate install-time purpose is present.

## Public findings

### 1. High: Install Time Lifecycle Scripts
- **Category:** Manifest
- **Confidence:** 90.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@test1230504/probe-7f3k2m-utils@1.0.0/package.json>)

Package defines install-time lifecycle scripts.

Public source snippet (untrusted):

```json
scripts.postinstall = node postinstall.js
```

### 2. Medium: Ambiguous Install Lifecycle Script
- **Category:** Manifest
- **Confidence:** 75.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@test1230504/probe-7f3k2m-utils@1.0.0/package.json>)

Install-time lifecycle script is not statically allowlisted and needs review.

Public source snippet (untrusted):

```json
scripts.postinstall = node postinstall.js
```

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

Package declares npm scripts.

### 4. Low: High Entropy Strings
- **Category:** Supply Chain
- **Confidence:** 55.0%

Package source contains high-entropy string patterns.

### 5. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 70.0%

Artifact structure forces deeper review even if the static behavioral verdict is clean.
