• Resource Management: Automatic worker cleanup and timeout handling

🔍 Dependency Confusion Detection

NullVoid includes advanced Dependency Confusion Detection to identify potential supply chain attacks where malicious packages are created to exploit package resolution vulnerabilities.

🎯 Detection Methods

Timeline Analysis

• Git History vs Registry Creation: Compares package creation dates with git commit history
• Suspicious Timing: Flags packages created suspiciously close to first git commits
• Risk Levels:
  • CRITICAL: Package created < 1 day before git history
  • HIGH: Package created < 7 days before git history
  • MEDIUM: Package created < 30 days before git history

Scope Analysis

• Private Scope Detection: Identifies packages using private scopes (@company, @internal, etc.)
• Namespace Conflicts: Detects potential namespace confusion attacks
• Registry Configuration: Warns about improper npm registry setup

Pattern Analysis

• Suspicious Naming: Detects typosquatting and naming confusion patterns
• Activity Analysis: Identifies packages with suspiciously low git activity
• Similarity Scoring: Uses Levenshtein distance for name similarity analysis

📋 Example Detection Output

🔍 Analyzing dependency confusion patterns...

⚠️  3 dependency confusion threat(s) detected:

1. DEPENDENCY_CONFUSION_TIMELINE: Package creation date suspiciously close to git history (2 days)
   Package: @company/internal-auth
   Severity: HIGH
   Details: Package created: 2023-12-01T00:00:00.000Z, First git commit: 2023-11-29T00:00:00.000Z

2. DEPENDENCY_CONFUSION_SCOPE: Private scope package may be vulnerable to dependency confusion
   Package: @company/internal-auth
   Severity: HIGH
   Details: Private scope '@company' detected. Ensure proper npm registry configuration.

3. DEPENDENCY_CONFUSION_PATTERN: Package name follows suspicious naming patterns
   Package: abc123def
   Severity: MEDIUM
   Details: Suspicious patterns: /^[a-z]+\d+[a-z]+$/

🛡️ Protection Recommendations

For Private Packages

• Use scoped packages: @yourcompany/package-name
• Configure .npmrc files properly
• Use private npm registries
• Implement package signing

For Public Packages

• Verify package authenticity
• Check git history and activity
• Use package-lock.json files
• Monitor for suspicious updates

⚙️ Configuration

Dependency confusion detection can be configured via environment variables:

# Enable/disable dependency confusion analysis
NULLVOID_DEPENDENCY_CONFUSION_ENABLED=true

# Adjust timeline thresholds (days)
NULLVOID_TIMELINE_SUSPICIOUS=30
NULLVOID_TIMELINE_HIGH_RISK=7
NULLVOID_TIMELINE_CRITICAL=1

# Registry request timeout (ms)
NULLVOID_REGISTRY_TIMEOUT=10000

🔧 Bug Fixes

GPG Signature Verification

• Fixed: timeoutRef.unref is not a function error during GPG signature checks
• Improved: Proper timeout handling using setTimeout instead of req.setTimeout
• Enhanced: Cleaner error handling and timeout cleanup
