The 2 urls point to a javascript redirect script that automatically redirect visitors to a fake codec download site. These fake codecs are known as DNSChanger. Anyone running phpbb should check out their servers.
At the time of this writing over 400,000 hits are shown in Google when you search for the urls.
If anyone has any information as to how the scripts are being injected or which exploit is being used please contact me at dnelson(shift+2)uploadmalware.com
