Features

🏗️ Rule Builder Pattern: Intuitive interface for creating YARA rules
📚 Pre-built Templates: Common templates for malware detection
🔍 Pattern Library: Extensive collection of malware detection patterns
✅ Validation: Built-in rule validation and testing
🚀 Performance: Parallel scanning capabilities
🔄 Import/Export: Support for JSON and other formats
📋 Documentation: Comprehensive documentation and examples

Installation

Add this to your Cargo.toml:

[dependencies]
yara-forge = "0.1.0"

Quick Start

use yara_forge::{RuleBuilder, ValidationOptions};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create a simple rule
    let rule = RuleBuilder::new("detect_suspicious")
        .with_metadata("author", "YARA Forge")
        .with_string("$suspicious_api", "CreateRemoteThread")
        .with_condition("$suspicious_api")
        .build()?;

    // Validate the rule
    let options = ValidationOptions {
        syntax_only: true,
        test_against_samples: false,
        max_file_size: 10 * 1024 * 1024,
        timeout: 30,
    };

    // Save the rule
    rule.save("detect_suspicious.yar")?;

    Ok(())
}

Advanced Usage

Using Templates

use yara_forge::templates::ransomware_template;

let rule = ransomware_template("detect_ransomware")
    .with_metadata("severity", "high")
    .build()?;

Pattern Matching

use yara_forge::patterns::{ENCRYPTION_APIS, PROCESS_INJECTION};

let rule = RuleBuilder::new("detect_malware")
    .with_patterns(ENCRYPTION_APIS)
    .with_patterns(PROCESS_INJECTION)
    .with_condition("2 of them")
    .build()?;

Parallel Scanning

use yara_forge::validation::parallel_scan;

let matches = parallel_scan("rules/malware.yar", "samples/", &options)?;
