For instance, it has been known for some time now that Java is not particularly safe, and the list of open issues does not seem to be decreasing.
But Flash too has had its share of problems lately, which has led to Apple blocking older versions of the plug-in.
I’ve decided I had enough of Flash Player being this intrusive. A definite possibility is that some OS X developers are being too careless with their own security, and not recognising the need to properly protect their certificates from hackers.At the time of writing, the compromised Apple developer ID certificate (MDK7FNV856, in the name of one Nikolay Nikolay Lastovka) has not been revoked.There are a variety of ways to exploit security holes in OS X Gatekeeper to allow malicious code to sneak onto computers, but presently it seems the simplest method of all is to sign your code with a developer's certificate.All of which raises the question — from where are the attackers getting their valid Apple developer certificates?These are all valid concerns that we’ll clear up, putting your mind at ease when it comes time to update Adobe Flash Player. Plug-ins (or "plugins" – both are correct) are software elements used by web browsers, often to display certain types of content such as Flash or Java.
