Tools
Core
Storage
end
Storage <--> FS[Local Filesystem]
Storage <-.-> S3[MinIO/S3 Storage]
Core <--> YARA[YARA Engine]
classDef external fill:#f9f,stroke:#333,stroke-width:2px;
classDef core fill:#bbf,stroke:#333,stroke-width:1px;

- **CI Tests**: Runs on every push and pull request to main and develop branches
- Runs tests, formatting, linting, and type checking
- Builds and tests Docker images
- Uploads test coverage reports to Codecov
- **Version Auto-increment**: Automatically increments version on pushes to main branch
- Updates version in pyproject.toml, setup.py, and Dockerfile
- Creates git tag for new version
- **Publish Release**: Triggered after successful version auto-increment
- Builds Docker images for multiple stages
- Generates release notes from git commits
- Creates GitHub release with artifacts
- Publishes Docker images to Docker Hub
These workflows ensure code quality and automate the release process.
### Status Checks
The following status checks run on pull requests:
- ✅ **Format Verification**: Ensures code follows Black and isort formatting standards
- ✅ **Lint Verification**: Validates code quality and compliance with coding standards
- ✅ **Test Execution**: Runs the full test suite to verify functionality

# Installation Guide
## Prerequisites
- Python 3.11 or higher
- uv package manager (recommended) or pip
- Docker (optional, for containerized deployment)
## Method 1: Local Installation
### 1. Clone the Repository
```bash
git clone https://github.com/ThreatFlux/YaraFlux.git
cd YaraFlux
```
### 2. Install Dependencies
Using uv (recommended):
```bash
make install # Basic installation
make dev-setup # Development installation with additional tools
```
Using pip:
```bash
python -m venv .venv
source .venv/bin/activate
pip install -e . # Basic installation
pip install -e ".[dev]" # Development installation
```
## Method 2: Docker Installation
### 1. Build the Image
```bash
make docker-build
```
### 2. Run the Container
```bash
make docker-run
```
Or manually with custom configuration:
```bash
docker run -p 8000:8000 \
-e JWT_SECRET_KEY=your_jwt_secret_key \
-e ADMIN_PASSWORD=your_admin_password \
threatflux/yaraflux-mcp-server:latest
```
## Configuration
### Environment Variables
Create a `.env` file with the following variables:
```env
JWT_SECRET_KEY=your_jwt_secret_key
ADMIN_PASSWORD=your_admin_password
DEBUG=true # Optional, for development
```
### Development Tools
For development, additional tools are available:
```bash
make dev-setup # Installs development dependencies
make format # Formats code with black and isort
make lint # Runs linters
make test # Runs tests
make coverage # Generates test coverage report
```
## Verifying Installation
1. Start the server:
```bash
make run
```
2. Test the installation:
```bash
# Create a test YARA rule
yaraflux rules create test_rule --content 'rule test { condition: true }'
# List rules
yaraflux rules list
# Scan a file
yaraflux scan url http://example.com/file.txt
```
## Troubleshooting
### Common Issues
1. **Command not found: yaraflux**
- Ensure you're in an activated virtual environment
- Verify installation with `pip list | grep yaraflux`
2. **ImportError: No module named 'yara'**
- Install system dependencies: `apt-get install yara`
- Reinstall yara-python: `pip install --force-reinstall yara-python`
3. **Permission denied when starting server**
- Ensure proper permissions for the port (default: 8000)
- Try running with sudo or use a different port
### Getting Help
- Check the logs: `tail -f yaraflux.log`
- Run with debug logging: `DEBUG=true make run`
- File an issue on GitHub if problems persist

# CLI Usage Guide
The YaraFlux CLI provides a comprehensive interface for managing YARA rules and performing scans.
## Global Options
```
--url URL YaraFlux server URL (default: http://localhost:8000)
--username USER Username for authentication
--password PASS Password for authentication
--token TOKEN JWT token for authentication
--timeout SECONDS Request timeout (default: 30s)
--output json|pretty Output format
--debug Enable debug logging
```
## Authentication
Login and obtain a JWT token:
```bash
yaraflux auth login --username USER --password PASS
```
## YARA Rules Management
### List Rules
```bash
yaraflux rules list [--source custom|community]
```
### Get Rule Details
```bash
yaraflux rules get NAME [--source custom|community] [--raw]
```
### Create New Rule
```bash
# From file
yaraflux rules create NAME --file path/to/rule.yar [--source custom|community]
# From content
yaraflux rules create NAME --content 'rule example { condition: true }' [--source custom|community]
```
### Update Rule
```bash
yaraflux rules update NAME --file path/to/rule.yar [--source custom|community]
```
### Delete Rule
```bash
yaraflux rules delete NAME [--source custom|community]
```
### Validate Rule
```bash
yaraflux rules validate --file path/to/rule.yar
```
### Import Rules
```bash
yaraflux rules import --url GITHUB_URL [--branch BRANCH]
```
## Scanning
### Scan URL
```bash
yaraflux scan url URL [--rules RULE1,RULE2] [--timeout SECONDS]
```
### Get Scan Result
```bash
yaraflux scan result SCAN_ID
```
## MCP Integration
### List MCP Tools
```bash
yaraflux mcp tools
```
### Invoke MCP Tool
```bash
yaraflux mcp invoke TOOL --params '{"param1": "value1"}'
```
## Examples
### Working with Rules
1. Create a basic YARA rule:
```bash
yaraflux rules create test_malware --content '
rule test_malware {
meta:
description = "Test rule for malware detection"
author = "YaraFlux"
strings:
$suspicious = "malware" nocase
condition:
$suspicious
}'
```
2. List all custom rules:
```bash
yaraflux rules list --source custom
```
3. Validate a rule file:
```bash
yaraflux rules validate --file malware_detection.yar
```
### Scanning Files
1. Scan a file from URL:
```bash
yaraflux scan url https://example.com/suspicious.exe --rules test_malware
```
2. Check scan results:
```bash
yaraflux scan result abc123-scan-id
```
## Environment Variables
The CLI supports configuration via environment variables:
```bash
export YARAFLUX_URL="http://localhost:8000"
export YARAFLUX_USERNAME="admin"
export YARAFLUX_PASSWORD="password"
export YARAFLUX_TOKEN="jwt-token"
```
## Output Formats
### Pretty (Default)
```bash
yaraflux rules list --output pretty
```
### JSON
```bash
yaraflux rules list --output json
```
## Error Handling
The CLI provides descriptive error messages and appropriate exit codes:
- Authentication errors (401)
- Permission errors (403)
- Not found errors (404)
- Validation errors (400)
- Server errors (500)
Example error output:
```
Error: Failed to create rule - Invalid rule syntax at line 3
```
## Scripting
The JSON output format makes it easy to use the CLI in scripts:
```bash
# Get rule names
rules=$(yaraflux rules list --output json | jq -r '.[].name')
# Scan multiple URLs
while read -r url; do
yaraflux scan url "$url" --rules "$rules"
done < urls.txt

# YaraFlux File Management
This document describes the file management features added to YaraFlux.
## Overview
The file management system in YaraFlux allows you to:
1. Upload files with metadata
2. List and download uploaded files
3. View file details and metadata
4. Analyze file content through string extraction and hex view
5. Manage files (delete, etc.)
## Architecture
The file management system is implemented with the following components:
- **Models** - Data models for file info, upload/download, and analysis
- **Storage Interface** - Abstract base class defining the storage operations
- **Storage Implementations** - Local file system and MinIO (S3-compatible) implementations
- **API Endpoints** - REST API for file operations
- **MCP Tools** - Model Context Protocol tools for Claude integration

# YaraFlux: Separated API and MCP Architecture
This document describes the separation of YaraFlux into two dedicated containers:
1. **API Container**: Provides a FastAPI backend with all YARA functionality
2. **MCP Client Container**: Implements the Model Context Protocol interface, forwarding requests to the API
## Architecture Overview
```

```
## Container Design
### API Container
The API Container exposes a RESTful API with the following features:
- JWT authentication for secure access
- Full YARA rule management
- File upload and scanning
- Storage management
- Detailed results and analytics
This container runs independently and can be used by any client that can make HTTP requests.
### MCP Client Container
The MCP Client Container:
- Implements the Model Context Protocol
- Acts as a thin client to the API Container
- Translates MCP tool calls into API requests
- Passes responses back to the AI assistant
- No direct YARA or storage functionality
## Implementation Steps
1. **API Container**:
- Use the existing FastAPI implementation
- Expose all YARA and file functionality via endpoints
- Ensure proper documentation and error handling
- Store configuration as environment variables
- Make all endpoints accessible via REST API
2. **MCP Client Container**:
- Create a lightweight MCP server
- Implement tool wrappers that call the API
- Handle authentication to the API
- Configure connection details via environment variables
- Forward all operations to the API container
## Communication Flow
1. **AI to MCP Client**:
- AI assistant calls MCP tool (e.g., "scan_data")
- MCP client processes parameters
2. **MCP Client to API**:
- MCP client translates tool call to HTTP request
- Makes authenticated API call to API container
3. **API to Storage & YARA**:
- API executes the requested operation
- Performs file/YARA operations as needed
- Generates response with results
4. **Response Flow**:
- API returns HTTP response to MCP client
- MCP client formats response for MCP protocol
- AI assistant receives results
## Benefits
- **Modularity**: Each container has a single responsibility
- **Scalability**: API container can scale independently of MCP clients
- **Maintainability**: Easier to update each component separately
- **Versatility**: API can be used by multiple clients (web UI, CLI, MCP)
- **Security**: Better isolation between components
## Docker Compose Configuration
A Docker Compose file can be used to start both containers together with proper networking:
```yaml
version: '3'
services:
api:
build:
context: .
dockerfile: Dockerfile.api
environment:
- JWT_SECRET_KEY=your-secret-key
- ADMIN_PASSWORD=your-admin-password
- DEBUG=true
volumes:
- yara_data:/app/data
ports:
- "8000:8000"
mcp:
build:
context: .
dockerfile: Dockerfile.mcp
environment:
- API_URL=http://api:8000
- API_USERNAME=admin
- API_PASSWORD=your-admin-password
depends_on:
- api
volumes:
yara_data:
```
This architecture provides a more robust and maintainable design for the YaraFlux system, allowing it to grow and adapt to different usage patterns.

# YARA Rules Guide
This guide covers creating, managing, and optimizing YARA rules in YaraFlux.
## YARA Rule Basics
### Rule Structure
```yara
rule rule_name {
meta:
description = "Rule description"
author = "Author name"
date = "2025-03-07"
version = "1.0"
strings:
$string1 = "suspicious_text" nocase
$string2 = { 45 76 69 6C } // hex pattern
$regex1 = /suspicious[0-9]+/ nocase
condition:
any of them
}
```
### Rule Components
1. **Rule Header**
- Unique name using alphanumeric characters and underscores
- Optional tags in square brackets
2. **Meta Section**
- Additional information about the rule
- Key-value pairs for documentation
- Common fields: description, author, date, version, reference
3. **Strings Section**
- Text strings
- Hexadecimal patterns
- Regular expressions
- Modifiers: nocase, wide, ascii, fullword
4. **Condition Section**
- Boolean expression determining match
- Operators: and, or, not
- Functions: any, all, them
- String count operations
- File property checks
## Best Practices
### Naming Conventions
- Use descriptive, unique names
- Follow pattern: category_threat_detail
- Example: `ransomware_lockbit_config`
### String Definition
```yara
rule good_strings {
strings:
// Text strings with modifiers
$text1 = "malicious" nocase fullword
$text2 = "evil" wide nocase
// Hex patterns with wildcards
$hex1 = { 45 ?? 69 6C }
// Regular expressions
$re1 = /suspicious[A-F0-9]{4}/
}
```
### Effective Conditions
```yara
rule good_conditions {
condition:
// Count matches
#text1 > 2 and
// Position checks
@text1 < @text2 and
// File size checks
filesize < 1MB and
// String presence
$hex1 and
// Multiple strings
2 of ($text*)
}
```
## Advanced Features
### Private Rules
```yara
private rule SharedCode {
strings:
$code = { 45 76 69 6C }
condition:
$code
}
rule DetectMalware {
condition:
SharedCode and filesize < 1MB
}
```
### Global Rules
```yara
global rule FileCheck {
condition:
filesize < 10MB
}
```
### External Variables
```yara
rule ConfigCheck {
condition:
ext_var == "expected_value"
}
```
## Performance Optimization
1. **String Pattern Order**
- Put most specific patterns first
- Use anchored patterns when possible
2. **Condition Optimization**
- Use early exit conditions
- Order conditions by computational cost
Example:
```yara
rule optimized {
strings:
$specific = "exact_match"
$general = /suspicious.*pattern/
condition:
filesize < 1MB and // Quick check first
$specific and // Specific match next
$general // Expensive regex last
}
```
## Testing Rules
### Validation
```bash
# Validate single rule
yaraflux rules validate --file rule.yar
# Validate rule content directly
yaraflux rules validate --content 'rule test { condition: true }'
```
### Test Scanning
```bash
# Create test file
echo "Test content" > test.txt
# Scan with specific rule
yaraflux scan url file://test.txt --rules test_rule
```
## Managing Rules
### Sources
1. **Custom Rules**
- Local rules you create
- Stored in custom rules directory
2. **Community Rules**
- Imported from trusted sources
- Read-only by default
### Organization
- Group related rules in files
- Use consistent naming
- Document with metadata
- Version control rules
### Maintenance
- Regular review and updates
- Remove outdated rules
- Track false positives/negatives
- Document changes
## Examples
### Malware Detection
```yara
rule detect_malware {
meta:
description = "Detect common malware patterns"
author = "YaraFlux"
version = "1.0"
strings:
$sus1 = "cmd.exe /c" nocase
$sus2 = "powershell.exe -enc" nocase
$sus3 = { 68 74 74 70 3A 2F 2F } // "http://"
condition:
2 of them
}
```
### File Type Detection
```yara
rule detect_pe {
meta:
description = "Detect PE files"
strings:
$mz = { 4D 5A }
$pe = { 50 45 00 00 }
condition:
$mz at 0 and $pe
}
```
### Complex Conditions
```yara
rule complex_detection {
meta:
description = "Advanced detection example"
strings:
$config = { 43 4F 4E 46 49 47 }
$encrypt = /encrypt[a-z]+/
$key = /key=[A-F0-9]{32}/
condition:
filesize < 1MB and
$config and
(#encrypt > 2 or $key)
}
```
