It is common for organizations to proxy web traffic so they can place restrictions on what websites can be visited by employees. To make the management of allowing or denying access to a large number of sites easier many web proxies utilize categorization engines to group sites into various subjects. Uncategorized sites are generally blocked. In this episode I show how it's easy to locate recently expired domains that have been categorized already, and can be utilized to get past web proxy filters. Additionally, I show how easy it is to set up a trusted certificate on the payload handler to encrypt the session using a custom cert.
