How does one know if Flash is legitimate?
This is mainly a paranoid question, but how do I know if a Flash installer is legitimate?
When I opened Safari today, I got prompted to update Flash. However, the window prompting the Flash update could have been launched from some open browser tab in Safari or another browser, couldn't it? So when I look at the window that prompts me to upgrade, what could I use as a sign to tell that this is a valid legitimate request to update?
As I am paranoid, I cancelled the update process and went to adobe.com and downloaded the update from there. In that way I at least know the origin of the file. However, surely that should not be necessary. Surely there is a way to recognise a legitimate update prompt?
