Python / Select Random User Agent
Select Random User Agent
Randomly selects a User-Agent string for requests to obscure testing identity.
python sqlmap.py -u "{http://www.example.com/vuln.php}" --random-agent python sqlmap.py -u "`{http://www.example.com/vuln.php`}" --random-agent #!/bin/bash
# Select Random User Agent
python sqlmap.py {{[-u|--url]}} "{{http://www.example.com/vuln.php}}" --random-agent import subprocess
# Select Random User Agent
# Make sure to replace <placeholders> with actual values
def run_command():
cmd = [
"python",
"sqlmap.py",
"-u",
"\"{http://www.example.com/vuln.php}\"",
"--random-agent"
]
try:
print(f"Executing: {' '.join(cmd)}")
subprocess.run(cmd, check=True)
except subprocess.CalledProcessError as e:
print(f"Error: {e}")
except FileNotFoundError:
print("Error: python not found. Please install it first.")
if __name__ == "__main__":
run_command() When To Use
When conducting automated tests against web applications to prevent blocking by fixed User-Agent strings.
Pro Tip
Monitor requests to identify if certain User-Agents lead to different server responses; prefer frequently used browsers.
Anatomy of Output
Understanding the result
[05:15:10] [INFO] using a random User-Agent Info Indicates that a random User-Agent will be employed.
[05:15:11] [INFO] sent request with User-Agent: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3' User-Agent Sent Displays the specific User-Agent used for the request.
[05:15:12] [SUCCESS] response received Request Result Shows that the request was successfully sent and a response received.
Power User Variants
Optimized versions
python sqlmap.py -u 'http://www.example.com/vuln.php' --random-agent --level=5 Increase the aggressiveness of the testing.
python sqlmap.py -u 'http://www.example.com/vuln.php' --random-agent --cookie='session=abc123' Send a session cookie while using random User-Agent.
Troubleshooting
Common pitfalls
sqlmap -u '...' --random-agent - ERROR: No response received
Solution: Check target URL for availability and proper endpoint status.
sqlmap -u '...' --random-agent - ERROR: Unsupported User-Agent
Solution: Verify that custom User-Agent, if provided, is correctly formatted.
sqlmap -u '...' --random-agent - ERROR: Blocking detected
Solution: Consider reducing request frequency or using more diverse User-Agents.
