Apple is not really know to publish clear end-of-support announcements for their products.

In our network (big university) we have strict policies and we do not allow unmatched systems. We were able to "forbid" Windows XP machines after Microsoft announced the end of support.

We would now like to do the same for OS X 10.6.

According to Wikipedia

Unsupported as of February 25, 2014, though the last security update happened in September 2013 and an update to the Mac App Store on Snow Leopard was made in January 2016.

Sadly, Apple made a minor non-security update to the system in January 2016 because of the Apple Store giving the impression that the system is not dead.

Are there known exploits for 10.6 that would allow me to show our community that the system is indeed not secure?
