* ✨ feat: add homoglyph and unicode lookalikes list Add a large set of unicodealikes and homoglyphs to the check-for-unicode script to improve detection of visually similar characters used in homograph and prompt-injection attacks. Key changes: - Include Cyrillic small and capital letters that resemble Latin characters (addresses CVE-2017-5116 style homograph risks). - Add Greek, Armenian, Thai, and other script characters that are commonly used as lookalikes. - Add Mathematical Alphanumeric Symbols and Fullwidth Latin characters used in obfuscated/prompt-injection attacks. - Expand comments and groupings to clarify character sources and attack vectors. Why: - Improve security by catching more spoofed or obfuscated input that could be used for phishing, homograph attacks, or adversarial prompt manipulation. * 🔒 feat(security): Add Unicode attack vector test suite Implement comprehensive test suite for Unicode-based security vulnerabilities, including: - Trojan Source attacks - Homograph attacks - Bidirectional text overrides - Zero-width character injections - Mathematical symbol impersonation These tests help identify potential security risks in code parsing and input validation mechanisms. * 📝 docs(readme): Update documentation for Unicode Security Scanner v2.0.0 Enhance README with comprehensive usage instructions, advanced scanning options, and detailed example outputs. Add sections for: - Command line options - Basic and advanced usage scenarios - Improved example outputs (standard and JSON modes) - Testing and validation information - Allowlist configuration details Highlights: - Expanded CLI option documentation - Added JSON output format example - Included test suite overview - Demonstrated severity filtering - Showcased allowlist configuration * 🤖 feat(unicode): Add comprehensive AI+ security release v2.0.0 Implement major security enhancements for Unicode detection: - Expand Unicode pattern detection to 150+ patterns - Add homograph detection for multiple scripts - Introduce advanced CLI options for flexible scanning - Improve false positive handling with byte-aligned matching - Enhance cross-platform compatibility - Implement structured JSON output and severity filtering - Add comprehensive test suite with attack vector coverage Addresses critical security concerns in AI and supply chain contexts * 🎯 Add Unicode Exclusion Flags and Enhanced Test Suite Implement advanced Unicode detection with context-aware exclusion flags for emojis and common typography. Adds comprehensive test coverage for UI and documentation scenarios, reducing false positives while maintaining robust security checks.
