## Security analysis

### Published attack-surface review

- **Summary:** The package exfiltrates host and local system-identifying data at npm preinstall. It sends the data to a third-party collaborator endpoint.

- **Trigger:** Automatic npm preinstall lifecycle execution.

- **Impact:** Leaks installation directory, home path, hostname, username, DNS configuration, and contents of /etc/passwd and /etc/hosts.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-07-27T09:43:56.076Z

### AI review details

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

- **Mechanism:** Install-time filesystem and host-data collection followed by HTTPS POST exfiltration.

- **Attack narrative:** During npm preinstall, package.json executes index.js. That script gathers host identity and network data, reads /etc/passwd and /etc/hosts if available, then sends the serialized result in an HTTPS POST to 5tzh3l2e1cetr1chf6osh4tg57b0zqnf.oastify.com.

- **Rationale:** Source directly implements unconsented install-time collection and exfiltration of local system data. This is concrete malicious behavior, not a package-aligned feature.

- **Files touched:** package.json, index.js, /etc/passwd, /etc/hosts

- **Network endpoints:** 5tzh3l2e1cetr1chf6osh4tg57b0zqnf.oastify.com

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json runs \`node index.js\` via preinstall., index.js collects home path, hostname, username, and DNS servers., index.js reads /etc/passwd and /etc/hosts when present., index.js POSTs collected data to an oastify.com host during installation.

- **Evidence against:** No benign application source or stated package functionality 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/jobber-app-template-react@1.0.1/package.json>)

Package defines install-time lifecycle scripts.

Public source snippet (untrusted):

```json
scripts.preinstall = node index.js
```

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

Package declares npm scripts.

### 3. Medium: Network
- **Category:** Source
- **Confidence:** 75.0%

Package source references network APIs.

### 4. Low: Filesystem
- **Category:** Source
- **Confidence:** 70.0%

Package source references filesystem APIs.

### 5. High: Host Fingerprint Exfiltration
- **Category:** Source
- **Confidence:** 86.0%
- **Path:** index.js
- **Public source:** [View source](<https://unpkg.com/jobber-app-template-react@1.0.1/index.js>)

Source collects local host identity data and sends it to an external endpoint.

Public source snippet (untrusted):

```javascript
L1: const os = require("os");
L2: const dns = require("dns");
L3: const fs = require("fs");
L4: const https = require("https");
L5: const packageJSON = require("./package.json");
L6: const packageName = packageJSON.name;
...
L10: p: packageName,  // Package name
L11: c: __dirname,    // Directory where the package is installed
L12: hd: os.homedir(),  // Home directory on the remote server
L13: hn: os.hostname(),  // Hostname of the remote server
L14: un: os.userInfo().username,  // Username on the remote server
...
L17: pjson: packageJSON,  // Full package.json data
```

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

Package source contains high-entropy string patterns.

### 7. High: Known Malware Source Similarity
- **Category:** Static
- **Confidence:** 97.0%
- **Path:** index.js
- **Public source:** [View source](<https://unpkg.com/jobber-app-template-react@1.0.1/index.js>)

Source file is highly similar to a previously finalized malicious package; route for source-aware review.

Public source snippet (untrusted):

```javascript
matchType = normalized_sha256
matchedPackage = tracker-radar-detector@1.0.1
matchedPath = index.js
matchedIdentity = npm:dHJhY2tlci1yYWRhci1kZXRlY3Rvcg:1.0.1
similarity = 1.000
summary = normalized source hash matched finalized malicious source
```

### 8. High: Known Malware Source Fingerprint Signature
- **Category:** Supply Chain
- **Confidence:** 94.0%
- **Path:** index.js
- **Public source:** [View source](<https://unpkg.com/jobber-app-template-react@1.0.1/index.js>)

Source fingerprint signature matches a known malicious package signature; route for source-aware review.

Public source snippet (untrusted):

```javascript
matchType = malicious_source_fingerprint_signature
signature = 5442fb9217b0dd0a
signatureType = suspicious_hashes
sourceLabel = final_verdict:malicious
matchedPackage = tracker-radar-detector@1.0.1
matchedPath = index.js
matchedIdentity = npm:dHJhY2tlci1yYWRhci1kZXRlY3Rvcg:1.0.1
