Mystery lab challenge

Try solving a random lab with the title and description hidden. As you'll have no prior knowledge of the type of vulnerability that you need to find and exploit, this is great for practicing recon and analysis before taking your Burp Suite Certified Practitioner exam.

In some of the labs, you have access to your own account with the credentials wiener:peter. If you can enumerate usernames, you may also be able to brute-force the login using the following username and password lists.
