Intomic (www.intomic.com) is a young New Zealand-based company offering anti-spam services, to both individuals and business customers. Our service doesn't require any software to install and therefore is always up to date with new filters immediately deployed onto all our customers mailboxes. Indeed, spammers are not only using PDF, but also Excel and Word documents. At Intomic Ltd, we have identified these new forms of attacks since July 14th and have already deployed ah-hoc filters.
