1 | # YaraFlux Documentation
2 |
3 | Welcome to the YaraFlux comprehensive documentation. This guide provides detailed information about YaraFlux, a powerful YARA scanning service with Model Context Protocol (MCP) integration designed for AI assistants.
4 |
5 | ## 🧩 Architecture
6 |
7 | YaraFlux implements a modular architecture that separates concerns between different layers:
8 |
9 | ```mermaid
10 | graph TD
11 | AI[AI Assistant] <-->|Model Context Protocol| MCP[MCP Server Layer]
12 | MCP <--> Tools[MCP Tools Layer]
13 | Tools <--> Core[Core Services]
14 | Core <--> Storage[Storage Layer]
15 |
16 | subgraph "YaraFlux MCP Server"
17 | MCP
18 | Tools
19 | Core
20 | Storage
21 | end
22 |
23 | Storage <--> FS[Local Filesystem]
24 | Storage <-.-> S3[MinIO/S3 Storage]
25 | Core <--> YARA[YARA Engine]
26 |
27 | classDef external fill:#f9f,stroke:#333,stroke-width:2px;
28 | classDef core fill:#bbf,stroke:#333,stroke-width:1px;
29 |
30 | class AI,FS,S3,YARA external;
31 | class Core,Tools,MCP,Storage core;
32 | ```
33 |
34 | The architecture consists of these key components:
35 | 1. **MCP Server Layer**: Handles communication with AI assistants using the Model Context Protocol
36 | 2. **MCP Tools Layer**: Implements functionality exposed to AI assistants
37 | 3. **Core Services**: Core functionality for YARA rule management and scanning
38 | 4. **Storage Layer**: Abstract storage interface with multiple backends
39 |
40 | For detailed architecture diagrams, see [Architecture Diagrams](architecture_diagram.md).

1 | # Installation Guide
2 |
3 | ## Prerequisites
4 |
5 | - Python 3.11 or higher
6 | - uv package manager (recommended) or pip
7 | - Docker (optional, for containerized deployment)
8 |
9 | ## Method 1: Local Installation
10 |
11 | ### 1. Clone the Repository
12 |
13 | ```bash
14 | git clone https://github.com/ThreatFlux/YaraFlux.git
15 | cd YaraFlux
16 | ```
17 |
18 | ### 2. Install Dependencies
19 |
20 | Using uv (recommended):
21 | ```bash
22 | make install # Basic installation
23 | make dev-setup # Development installation with additional tools
24 | ```
25 |
26 | Using pip:
27 | ```bash
28 | python -m venv .venv
29 | source .venv/bin/activate
30 | pip install -e . # Basic installation
31 | pip install -e ".[dev]" # Development installation
32 | ```
33 |
34 | ## Method 2: Docker Installation
35 |
36 | ### 1. Build the Image
37 |
38 | ```bash
39 | make docker-build
40 | ```
41 |
42 | ### 2. Run the Container
43 |
44 | ```bash
45 | make docker-run
46 | ```
47 |
48 | Or manually with custom configuration:
49 | ```bash
50 | docker run -p 8000:8000 \
51 | -e JWT_SECRET_KEY=your_jwt_secret_key \
52 | -e ADMIN_PASSWORD=your_admin_password \
53 | threatflux/yaraflux-mcp-server:latest
54 | ```
55 |
56 | ## Configuration
57 |
58 | ### Environment Variables
59 |
60 | Create a `.env` file with the following variables:
61 |
62 | ```env
63 | JWT_SECRET_KEY=your_jwt_secret_key
64 | ADMIN_PASSWORD=your_admin_password
65 | DEBUG=true # Optional, for development
66 | ```
67 |
68 | ### Development Tools
69 |
70 | For development, additional tools are available:
71 | ```bash
72 | make dev-setup # Installs development dependencies
73 | make format # Formats code with black and isort
74 | make lint # Runs linters
75 | make test # Runs tests
76 | make coverage # Generates test coverage report
77 | ```
78 |
79 | ## Verifying Installation
80 |
81 | 1. Start the server:
82 | ```bash
83 | make run
84 | ```
85 |
86 | 2. Test the installation:
87 | ```bash
88 | # Create a test YARA rule
89 | yaraflux rules create test_rule --content 'rule test { condition: true }'
90 |
91 | # List rules
92 | yaraflux rules list
93 |
94 | # Scan a file
95 | yaraflux scan url http://example.com/file.txt
96 | ```
97 |
98 | ## Troubleshooting
99 |
100 | ### Common Issues
101 |
102 | 1. **Command not found: yaraflux**
103 | - Ensure you're in an activated virtual environment
104 | - Verify installation with `pip list | grep yaraflux`
105 |
106 | 2. **ImportError: No module named 'yara'**
107 | - Install system dependencies: `apt-get install yara`
108 | - Reinstall yara-python: `pip install --force-reinstall yara-python`
109 |
110 | 3. **Permission denied when starting server**
111 | - Ensure proper permissions for the port (default: 8000)
112 | - Try running with sudo or use a different port
113 |
114 | ### Getting Help
115 |
116 | - Check the logs: `tail -f yaraflux.log`
117 | - Run with debug logging: `DEBUG=true make run`
118 | - File an issue on GitHub if problems persist
119 |
```

1 | # CLI Usage Guide
2 |
3 | The YaraFlux CLI provides a comprehensive interface for managing YARA rules and performing scans.
4 |
5 | ## Global Options
6 |
7 | ```
8 | --url URL YaraFlux server URL (default: http://localhost:8000)
9 | --username USER Username for authentication
10 | --password PASS Password for authentication
11 | --token TOKEN JWT token for authentication
12 | --timeout SECONDS Request timeout (default: 30s)
13 | --output json|pretty Output format
14 | --debug Enable debug logging
15 | ```
16 |
17 | ## Authentication
18 |
19 | Login and obtain a JWT token:
20 | ```bash
21 | yaraflux auth login --username USER --password PASS
22 | ```
23 |
24 | ## YARA Rules Management
25 |
26 | ### List Rules
27 | ```bash
28 | yaraflux rules list [--source custom|community]
29 | ```
30 |
31 | ### Get Rule Details
32 | ```bash
33 | yaraflux rules get NAME [--source custom|community] [--raw]
34 | ```
35 |
36 | ### Create New Rule
37 | ```bash
38 | # From file
39 | yaraflux rules create NAME --file path/to/rule.yar [--source custom|community]
40 |
41 | # From content
42 | yaraflux rules create NAME --content 'rule example { condition: true }' [--source custom|community]
43 | ```
44 |
45 | ### Update Rule
46 | ```bash
47 | yaraflux rules update NAME --file path/to/rule.yar [--source custom|community]
48 | ```
49 |
50 | ### Delete Rule
51 | ```bash
52 | yaraflux rules delete NAME [--source custom|community]
53 | ```
54 |
55 | ### Validate Rule
56 | ```bash
57 | yaraflux rules validate --file path/to/rule.yar
58 | ```
59 |
60 | ### Import Rules
61 | ```bash
62 | yaraflux rules import --url GITHUB_URL [--branch BRANCH]
63 | ```
64 |
65 | ## Scanning
66 |
67 | ### Scan URL
68 | ```bash
69 | yaraflux scan url URL [--rules RULE1,RULE2] [--timeout SECONDS]
70 | ```
71 |
72 | ### Get Scan Result
73 | ```bash
74 | yaraflux scan result SCAN_ID
75 | ```
76 |
77 | ## MCP Integration
78 |
79 | ### List MCP Tools
80 | ```bash
81 | yaraflux mcp tools
82 | ```
83 |
84 | ### Invoke MCP Tool
85 | ```bash
86 | yaraflux mcp invoke TOOL --params '{"param1": "value1"}'
87 | ```
88 |
89 | ## Examples
90 |
91 | ### Working with Rules
92 |
93 | 1. Create a basic YARA rule:
94 | ```bash
95 | yaraflux rules create test_malware --content '
96 | rule test_malware {
97 | meta:
98 | description = "Test rule for malware detection"
99 | author = "YaraFlux"
100 | strings:
101 | $suspicious = "malware" nocase
102 | condition:
103 | $suspicious
104 | }'
105 | ```
106 |
107 | 2. List all custom rules:
108 | ```bash
109 | yaraflux rules list --source custom
110 | ```
111 |
112 | 3. Validate a rule file:
113 | ```bash
114 | yaraflux rules validate --file malware_detection.yar
115 | ```
116 |
117 | ### Scanning Files
118 |
119 | 1. Scan a file from URL:
120 | ```bash
121 | yaraflux scan url https://example.com/suspicious.exe --rules test_malware
122 | ```
123 |
124 | 2. Check scan results:
125 | ```bash
126 | yaraflux scan result abc123-scan-id
127 | ```
128 |
129 | ## Environment Variables
130 |
131 | The CLI supports configuration via environment variables:
132 |
133 | ```bash
134 | export YARAFLUX_URL="http://localhost:8000"
135 | export YARAFLUX_USERNAME="admin"
136 | export YARAFLUX_PASSWORD="password"
137 | export YARAFLUX_TOKEN="jwt-token"
138 | ```
139 |
140 | ## Output Formats
141 |
142 | ### Pretty (Default)
143 | ```bash
144 | yaraflux rules list --output pretty
145 | ```
146 |
147 | ### JSON
148 | ```bash
149 | yaraflux rules list --output json
150 | ```
151 |
152 | ## Error Handling
153 |
154 | The CLI provides descriptive error messages and appropriate exit codes:
155 |
156 | - Authentication errors (401)
157 | - Permission errors (403)
158 | - Not found errors (404)
159 | - Validation errors (400)
160 | - Server errors (500)
161 |
162 | Example error output:
163 | ```
164 | Error: Failed to create rule - Invalid rule syntax at line 3
165 | ```
166 |
167 | ## Scripting
168 |
169 | The JSON output format makes it easy to use the CLI in scripts:
170 |
171 | ```bash
172 | # Get rule names
173 | rules=$(yaraflux rules list --output json | jq -r '.[].name')
174 |
175 | # Scan multiple URLs
176 | while read -r url; do
177 | yaraflux scan url "$url" --rules "$rules"
178 | done < urls.txt
179 |
```

1 | # YaraFlux File Management
2 |
3 | This document describes the file management features added to YaraFlux.
4 |
5 | ## Overview
6 |
7 | The file management system in YaraFlux allows you to:
8 |
9 | 1. Upload files with metadata
10 | 2. List and download uploaded files
11 | 3. View file details and metadata
12 | 4. Analyze file content through string extraction and hex view
13 | 5. Manage files (delete, etc.)
14 |
15 | ## Architecture
16 |
17 | The file management system is implemented with the following components:
18 |
19 | - **Models** - Data models for file info, upload/download, and analysis
20 | - **Storage Interface** - Abstract base class defining the storage operations
21 | - **Storage Implementations** - Local file system and MinIO (S3-compatible) implementations
22 | - **API Endpoints** - REST API for file operations
23 | - **MCP Tools** - Model Context Protocol tools for Claude integration

46 | ## Container Design
47 |
48 | ### API Container
49 |
50 | The API Container exposes a RESTful API with the following features:
51 | - JWT authentication for secure access
52 | - Full YARA rule management
53 | - File upload and scanning
54 | - Storage management
55 | - Detailed results and analytics
56 |
57 | This container runs independently and can be used by any client that can make HTTP requests.
58 |
59 | ### MCP Client Container
60 |
61 | The MCP Client Container:
62 | - Implements the Model Context Protocol
63 | - Acts as a thin client to the API Container
64 | - Translates MCP tool calls into API requests
65 | - Passes responses back to the AI assistant
66 | - No direct YARA or storage functionality
67 |
68 | ## Implementation Steps
69 |
70 | 1. **API Container**:
71 | - Use the existing FastAPI implementation
72 | - Expose all YARA and file functionality via endpoints
73 | - Ensure proper documentation and error handling
74 | - Store configuration as environment variables
75 | - Make all endpoints accessible via REST API
76 |
77 | 2. **MCP Client Container**:
78 | - Create a lightweight MCP server
79 | - Implement tool wrappers that call the API
80 | - Handle authentication to the API
81 | - Configure connection details via environment variables
82 | - Forward all operations to the API container
83 |
84 | ## Communication Flow
85 |
86 | 1. **AI to MCP Client**:
87 | - AI assistant calls MCP tool (e.g., "scan_data")
88 | - MCP client processes parameters
89 |
90 | 2. **MCP Client to API**:
91 | - MCP client translates tool call to HTTP request
92 | - Makes authenticated API call to API container
93 |
94 | 3. **API to Storage & YARA**:
95 | - API executes the requested operation
96 | - Performs file/YARA operations as needed
97 | - Generates response with results
98 |
99 | 4. **Response Flow**:
100 | - API returns HTTP response to MCP client
101 | - MCP client formats response for MCP protocol
102 | - AI assistant receives results
103 |
104 | ## Benefits
105 |
106 | - **Modularity**: Each container has a single responsibility
107 | - **Scalability**: API container can scale independently of MCP clients
108 | - **Maintainability**: Easier to update each component separately
109 | - **Versatility**: API can be used by multiple clients (web UI, CLI, MCP)
110 | - **Security**: Better isolation between components
111 |
112 | ## Docker Compose Configuration
113 |
114 | A Docker Compose file can be used to start both containers together with proper networking:
115 |
116 | ```yaml
117 | version: '3'
118 | services:
119 | api:
120 | build:
121 | context: .
122 | dockerfile: Dockerfile.api
123 | environment:
124 | - JWT_SECRET_KEY=your-secret-key
125 | - ADMIN_PASSWORD=your-admin-password
126 | - DEBUG=true
127 | volumes:
128 | - yara_data:/app/data
129 | ports:
130 | - "8000:8000"
131 |
132 | mcp:
133 | build:
134 | context: .
135 | dockerfile: Dockerfile.mcp
136 | environment:
137 | - API_URL=http://api:8000
138 | - API_USERNAME=admin
139 | - API_PASSWORD=your-admin-password
140 | depends_on:
141 | - api
142 |
143 | volumes:
144 | yara_data:
145 | ```
146 |
147 | This architecture provides a more robust and maintainable design for the YaraFlux system, allowing it to grow and adapt to different usage patterns.

16 | strings:
17 | $string1 = "suspicious_text" nocase
18 | $string2 = { 45 76 69 6C } // hex pattern
19 | $regex1 = /suspicious[0-9]+/ nocase
20 |
21 | condition:
22 | any of them
23 | }
24 | ```
25 |
26 | ### Rule Components
27 |
28 | 1. **Rule Header**
29 | - Unique name using alphanumeric characters and underscores
30 | - Optional tags in square brackets
31 |
32 | 2. **Meta Section**
33 | - Additional information about the rule
34 | - Key-value pairs for documentation
35 | - Common fields: description, author, date, version, reference
36 |
37 | 3. **Strings Section**
38 | - Text strings
39 | - Hexadecimal patterns
40 | - Regular expressions
41 | - Modifiers: nocase, wide, ascii, fullword
42 |
43 | 4. **Condition Section**
44 | - Boolean expression determining match
45 | - Operators: and, or, not
46 | - Functions: any, all, them
47 | - String count operations
48 | - File property checks
49 |
50 | ## Best Practices
51 |
52 | ### Naming Conventions
53 | - Use descriptive, unique names
54 | - Follow pattern: category_threat_detail
55 | - Example: `ransomware_lockbit_config`
56 |
57 | ### String Definition
58 | ```yara
59 | rule good_strings {
60 | strings:
61 | // Text strings with modifiers
62 | $text1 = "malicious" nocase fullword
63 | $text2 = "evil" wide nocase
64 |
65 | // Hex patterns with wildcards
66 | $hex1 = { 45 ?? 69 6C }
67 |
68 | // Regular expressions
69 | $re1 = /suspicious[A-F0-9]{4}/
70 | }
71 | ```
72 |
73 | ### Effective Conditions
74 | ```yara
75 | rule good_conditions {
76 | condition:
77 | // Count matches
78 | #text1 > 2 and
79 |
80 | // Position checks
81 | @text1 < @text2 and
82 |
83 | // File size checks
84 | filesize < 1MB and
85 |
86 | // String presence
87 | $hex1 and
88 |
89 | // Multiple strings
90 | 2 of ($text*)
91 | }
92 | ```
93 |
94 | ## Advanced Features
95 |
96 | ### Private Rules
97 | ```yara
98 | private rule SharedCode {
99 | strings:
100 | $code = { 45 76 69 6C }
101 | condition:
102 | $code
103 | }
104 |
105 | rule DetectMalware {
106 | condition:
107 | SharedCode and filesize < 1MB
108 | }
109 | ```
110 |
111 | ### Global Rules
112 | ```yara
113 | global rule FileCheck {
114 | condition:
115 | filesize < 10MB
116 | }
117 | ```
118 |
119 | ### External Variables
120 | ```yara
121 | rule ConfigCheck {
122 | condition:
123 | ext_var == "expected_value"
124 | }
125 | ```
126 |
127 | ## Performance Optimization
128 |
129 | 1. **String Pattern Order**
130 | - Put most specific patterns first
131 | - Use anchored patterns when possible
132 |
133 | 2. **Condition Optimization**
134 | - Use early exit conditions
135 | - Order conditions by computational cost
136 |
137 | Example:
138 | ```yara
139 | rule optimized {
140 | strings:
141 | $specific = "exact_match"
142 | $general = /suspicious.*pattern/
143 |
144 | condition:
145 | filesize < 1MB and // Quick check first
146 | $specific and // Specific match next
147 | $general // Expensive regex last
148 | }
149 | ```
150 |
151 | ## Testing Rules
152 |
153 | ### Validation
154 | ```bash
155 | # Validate single rule
156 | yaraflux rules validate --file rule.yar
157 |
158 | # Validate rule content directly
159 | yaraflux rules validate --content 'rule test { condition: true }'
160 | ```
161 |
162 | ### Test Scanning
163 | ```bash
164 | # Create test file
165 | echo "Test content" > test.txt
166 |
167 | # Scan with specific rule
168 | yaraflux scan url file://test.txt --rules test_rule
169 | ```
170 |
171 | ## Managing Rules
172 |
173 | ### Sources
174 | 1. **Custom Rules**
175 | - Local rules you create
176 | - Stored in custom rules directory
177 |
178 | 2. **Community Rules**
179 | - Imported from trusted sources
180 | - Read-only by default
181 |
182 | ### Organization
183 | - Group related rules in files
184 | - Use consistent naming
185 | - Document with metadata
186 | - Version control rules
187 |
188 | ### Maintenance
189 | - Regular review and updates
190 | - Remove outdated rules
191 | - Track false positives/negatives
192 | - Document changes
193 |
194 | ## Examples
195 |
196 | ### Malware Detection
197 | ```yara
198 | rule detect_malware {
199 | meta:
200 | description = "Detect common malware patterns"
201 | author = "YaraFlux"
202 | version = "1.0"
203 |
204 | strings:
205 | $sus1 = "cmd.exe /c" nocase
206 | $sus2 = "powershell.exe -enc" nocase
207 | $sus3 = { 68 74 74 70 3A 2F 2F } // "http://"
208 |
209 | condition:
210 | 2 of them
211 | }
212 | ```
213 |
214 | ### File Type Detection
215 | ```yara
216 | rule detect_pe {
217 | meta:
218 | description = "Detect PE files"
219 |
220 | strings:
221 | $mz = { 4D 5A }
222 | $pe = { 50 45 00 00 }
223 |
224 | condition:
225 | $mz at 0 and $pe
226 | }
227 | ```
228 |
229 | ### Complex Conditions
230 | ```yara
231 | rule complex_detection {
232 | meta:
233 | description = "Advanced detection example"
234 |
235 | strings:
236 | $config = { 43 4F 4E 46 49 47 }
237 | $encrypt = /encrypt[a-z]+/
238 | $key = /key=[A-F0-9]{32}/
239 |
240 | condition:
241 | filesize < 1MB and
242 | $config and
