I was browsing the web today and got a very legit looking warning that my player crashed and had to be updated to view the content on the page. A very legit Adobe Flash player installer came up and tried to get me to install their fake update to Flash player. Who knows what it would have done but it's out in the wild and will certainly fool a lot of people.
That site seems to be closed now.
It's unfortunately very much open -- I just got hit with an attempt to download FlashPlayer-11-macos.pkg http://adobeupdatemanager.org/FlashPlayer-11-7-macos.zip, http://adobeupdatemanager.org/flashplugin/7f
