"These kinds of targeted attacks using PDFs have been going on for quite a while," said Hypponen. "There's nothing new technically in any of these attacks, including the ones against Google and Adobe."
The interesting things here are that both companies have know about the security breaches for weeks and that everyone, including Adobe, has known about the PDF exploits for months. Why a) Were people on secure computers still allowed to use Reader for PDF? b) Why did it take so frikking long to patch Reader?

Sumatra is my choice for reader.
