Where are Illustrator CS4 updates?

Can not find Illustrator CS4 updates link.  It seems it should be here Adobe Security Bulletins and Advisories 

but the earliest update listed there is for Illustrator CS5. Moreover that link lead to this page Adobe Security Bulletins and Advisories.

That version is not officially supported anymore.

Is it even possible to activate an Illustrator CS4 installation? Adobe provided activation free installers for CS2 products and activation-free serial numbers for CS3 products. I don't remember them doing anything for CS4. Are the activation servers even still running for CS5, CS5.5 or CS6 applications?

CS5 and CS6 is still possible AFAIK.

I'm not sure about CS4. But when you need security updates, then I guess that the software itself is already installed.
