You know my opinion on collaboration between countries, on public-private-partnerships as well as on collaboration between companies.
Since quite a while we run a program called MAPP â€“ the Microsoft Active Protections Program, where we share vulnerability information with security vendors to help them to get signatures out to our joint customers the moment we release a security update.
Additionally, we know form our data (see the Security Intelligence Report) that PDF is the most exploited file format. Therefore I think it is a great signal that Adobe will join the MAPP program to tighten our joint collaboration.
It is another clear signal that we are up for action to address the security challenges in the ecosystem.
