Yokoso is a project focused on creating fingerprinting code that is deliverable through some form of client attack. This can be used during penetration tests that combine network and web applications. One of the most common questions we hear is “so what can you do with XSS?” and we hope that Yokoso! answers that question.We will create JavaScript and Flash objects that are able to be delivered via XSS attacks. These code payloads will contain the fingerprinting information used to map out a network and the devices and software it contains.
