Yes. I know. It was Friday. And for you or anyone else reading this there's a slight new "wrinkle" with this new flash player installer (11.3.300.257).
The latest flash player installer now installs a new /LaunchDaemons/com.adobe.fpsaud.plist which will fire every hour to launch another newly installed code file, /Library/Application Support/Adobe/Flash Player Install Manager/fpsaud, which is used to check for updates.
If you don't want this behavior then open the newly installed Adobe Player system preference, Advanced tab, and under Updates choose "Never check for updates". You can remove the launch daemon after that.
If you don't turn off update checking and you are using Little Snitch or Hands Off then those should alert to fpsaud attempting to call out. Don't confuse this with malware attempting to call out. It's not.
