According to Websense, the 6Music and 1Xtra websites have somehow become injected with malicious code:
The injected iframe occurs at the foot of the BBC 6 Music Web page, and loads code from a Web site in the .co.cc TLD. The iFrame injected into the Radio 1Xtra Web page leads to the same malicious site.I think the takeaway message from this is: it could happen to anyone. Do take care online.
If an unprotected user browsed to the site they would be faced with drive-by downloads, meaning that simply browsing to the page is enough to get infected with a malicious executable.
