DoubleClick, an internet advertising technology and service firm, also a subsidiary of Google, has unintentionally served millions of infected advertising to millions of people on a few popular and well visited sites such as Last.fm. Once the pages rendered, and the online banner adverts loaded, they dropped the Zemot malware on to the computers of those visitors.
Shocking? Perhaps. But it's just human nature. There will always be people who want to take shortcuts and exploit loopholes.
Could have happened to any other advertising technology firm - and likely it happens daily. Implications for Google? They are not infallible.
