Question 1

How do I find the Client ID for cognito scanner?

Accepted Answer

You can extract the Client ID by analyzing HTTP requests with a proxy like Burp, examining JavaScript files for obfuscated parameters, or checking headers and other files in the application. The tool's README provides specific guidance on these methods for parameter discovery.

Question 2

What's the difference between cognito scanner and AWS Inspector for Cognito security?

Accepted Answer

Cognito Scanner is a specialized, offensive tool that simulates specific attacks like account creation and privilege escalation, while AWS Inspector focuses on automated vulnerability assessments and compliance checks across AWS services. Use Cognito Scanner for targeted penetration testing and Inspector for broader security monitoring.

Question 3

How to run the account oracle attack with cognito scanner?

Accepted Answer

Use the command 'cognito-scanner account-oracle --client_id=YOUR_ID --region=REGION --file=usernames.txt' after installation. Ensure you have a file with usernames to test, and the script will identify existing accounts by exploiting information leakage, as shown in the README example.

Question 4

Is cognito scanner safe to use on production systems?

Accepted Answer

Only use it on systems you own or have explicit permission to test, as attacks like unwanted account creation can create real user entries or trigger alerts. It's designed for security assessments, so always test in isolated environments first to avoid disruptions.

Question 5

Can cognito scanner be integrated into CI/CD pipelines?

Accepted Answer

While possible by scripting the commands, the tool lacks built-in CI/CD integration or APIs, so you would need to manually incorporate it and handle output parsing for automated checks, which adds complexity.

Question 6

What are the common pitfalls when using cognito scanner?

Accepted Answer

Common issues include failing to correctly extract parameters like Pool ID from applications, which prevents attack execution, and misunderstanding the output format for identity pool escalation, which requires careful handling of temporary credentials.
