• Automatic Language Detection: Identifies programming language even with missing or misleading file extensions
• Content-Based Analysis: Analyzes code semantics, not just file extensions

🛡️ Advanced Malware Detection

Detects all forms of malicious and suspicious code:

• Code Execution: eval, exec, system, shell_exec, Runtime.exec, Process.Start
• Obfuscation: Base64, Hex, CharCode, ROT13, gzinflate, atob, URL encoding
• File Injections: Remote file inclusion, dynamic includes, path traversal
• Shell Commands: exec, system, shell_exec, popen, subprocess calls
• Database Attacks: SQL injection patterns, unsafe queries
• XSS Risks: innerHTML, document.write, unsafe DOM manipulation
• Anti-Analysis: Debugger statements, anti-debugging techniques
• Suspicious Patterns: Hardcoded credentials, external downloads, self-replication

🔬 Multi-Layer Analysis Engine

• Pattern Matching: Signature-based detection with 500+ malware patterns
• AST Parsing: Abstract Syntax Tree analysis for semantic understanding
• Obfuscation Decoding: Automatically decodes and analyzes hidden payloads
• Control Flow Analysis: Detects suspicious logic and control structures
• Data Flow Analysis: Tracks user input to dangerous sinks (taint analysis)

• Detailed Findings: File path, language, threat type, severity, line numbers
• Remediation Suggestions: Actionable recommendations for each threat
• CVSS Scoring: Common Vulnerability Scoring System integration
• CWE Mapping: Common Weakness Enumeration identifiers

🎯 Professional Features

python -m secuscan scan ./project -o report.json -f json

HTML report:

python -m secuscan scan ./project -o report.html -f html

Markdown report:

python -m secuscan scan ./project -o report.md -f markdown

Configuration

Use a custom configuration file:

python -m secuscan scan ./project --config secuscan_config.ini

List Supported Languages

python -m secuscan languages

Decode Obfuscated Content

python -m secuscan decode ./suspicious-file.js

Get Help

python -m secuscan --help
python -m secuscan scan --help

🔍 Detection Capabilities

Code Execution Patterns

• PHP: eval, assert, preg_replace /e, create_function, exec, system, shell_exec
• JavaScript: eval, Function constructor, setTimeout/setInterval with strings
• Python: eval, exec, compile, os.system, subprocess calls
• Java: Runtime.exec, ProcessBuilder, reflection abuse
• C/C++: system, popen, gets, strcpy (buffer overflow)
• C#: Process.Start, cmd.exe references
• Go: exec.Command
• Ruby: eval, backtick execution, system
• PowerShell: Invoke-Expression, IEX, bypass flags

Obfuscation Techniques Detected

• Base64 encoding (multiple layers)
• Hex-encoded strings
• Unicode escapes
• CharCode obfuscation
• ROT13 encoding
• gzinflate compression
• URL encoding
• String concatenation
• Array join obfuscation

Suspicious Behaviors

• Hardcoded credentials (passwords, API keys, tokens)
• Remote file downloads and execution
• Self-replicating code
• Infinite loops (DoS potential)
• Deep nesting (obfuscation indicator)
• Anti-debugging techniques
• External code hosting URLs (Pastebin, Gist)
