Using URL Dump we can dump the HTML content:

Dumped HTML Content

From the dumped data, we can see it is the Incognito exploit kit.

Extacted malicious URLs:

hxxp:// bigdeal . my/ZyYJZ7F0/js.js

The malicious URLs redirect users to another malicious URL:

hxxp:// 69.163.34. 134 /showthread.php?t=977334ca118fcb8c

If we use URL Dump and we set the user-agent to Java, when we dump the content of the new malicious URL we can see it recognises from the user-agent that the user is using Java and the exploit tries to serve the infected Java applet:
