## Security analysis

### Published attack-surface review

- **Summary:** A caller that supplies a crafted local video filename to media processing can influence an ffmpeg command executed through a shell. No install-time attack surface is established.

- **Trigger:** Application code invokes video media-message preparation with a crafted local file path.

- **Impact:** Arbitrary shell command execution with the host application's privileges.

- **Evidence paths:** lib/Utils/messages-media.js, lib/Utils/messages.js, package.json, engine-requirements.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-07T00:35:08.254Z

### AI review details

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

- **Mechanism:** unsafely interpolated filename passed to child\_process.exec

- **Rationale:** The package is not shown to contain malicious install-time or covert behavior, but it exposes a concrete runtime shell-injection vulnerability through normal media processing.

- **Files touched:** lib/Utils/messages-media.js, lib/Utils/messages.js, package.json, engine-requirements.js

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 95.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Critical Vulnerability

- **False-positive risk:** Low

- **Evidence for:** lib/Utils/messages-media.js builds an ffmpeg shell command by interpolating a media file path, then calls child\_process.exec., The video-thumbnail path reaches that helper from lib/Utils/messages.js; a caller-supplied local video path can reach the shell., This is a runtime command-injection/RCE risk, though no covert payload or exfiltration was found.

- **Evidence against:** package.json preinstall only runs engine-requirements.js, which checks Node's major version and exits on unsupported versions., No eval/vm/dynamic remote-code loader, credential harvesting, or AI-agent configuration mutation was found., Network code implements WhatsApp Web/media operations and explicit version checks, not install-time callbacks., lib/index.js only clears the console and prints package branding at import time.

## Public findings

### 1. High: Install Time Lifecycle Scripts
- **Category:** Manifest
- **Confidence:** 90.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/ynastore-baileys@1.0.21/package.json>)

Package defines install-time lifecycle scripts.

Public source snippet (untrusted):

```json
scripts.preinstall = node ./engine-requirements.js
```

### 2. Low: Non Install Lifecycle Scripts
- **Category:** Manifest
- **Confidence:** 80.0%

Package declares lifecycle scripts that are not normally run for registry tarball installs.

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

Package declares npm scripts.

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

Package source references network APIs.

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

Package source references filesystem APIs.

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

Package source contains high-entropy string patterns.

### 7. Low: Url Strings
- **Category:** Supply Chain
- **Confidence:** 65.0%

Package source contains URL literals.

### 8. Medium: Oversized Source File
- **Category:** Artifact Inventory
- **Confidence:** 70.0%
- **Path:** WAProto/index.js
- **Public source:** [View source](<https://unpkg.com/ynastore-baileys@1.0.21/WAProto/index.js>)

Package contains source files above the normal full-analysis size ceiling.

Public source snippet (untrusted):

```javascript
path = WAProto/index.js
kind = oversized_source_file
sizeBytes = 8472622
magicHex = [redacted]
```

### 9. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 100.0%

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

### 10. Medium: Git Dependency
- **Category:** Manifest
- **Confidence:** 85.0%

Package manifest contains a git dependency.

### 11. High: Known Malware Source Similarity
- **Category:** Static
- **Confidence:** 97.0%
- **Path:** lib/Utils/messages-media.js
- **Public source:** [View source](<https://unpkg.com/ynastore-baileys@1.0.21/lib/Utils/messages-media.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 = my-auto-follow@1.0.3
matchedPath = lib/Utils/messages-media.js
matchedIdentity = npm:bXktYXV0by1mb2xsb3c:1.0.3
similarity = 1.000
summary = normalized source hash matched finalized malicious source
```
