The next step is to host the malicious content that the attacker wishes to distribute. One option is for the attacker to host the malicious content on their own server. However, because of the difficulty in directing users to a new page, it may also be hosted on a compromised legitimate website, or a legitimate website unknowingly distributing the attackers content through a third party service (e.g. an advertisement). When the content is loaded by the client, the attacker will analyze the fingerprint of the client in order to tailor the code to exploit vulnerabilities specific to that client.
