Have you ever wondered how Facebook is able to automatically display your Instagram photos? How about how Evernote syncs notes between your computer and smartphone? If so, then it’s time to get excited!

In this course, we walk you through what it takes for companies to link their systems together. We start off easy, defining some of the tech lingo you may have heard before, but didn’t fully understand. From there, each lesson introduces something new, slowly building up to the point where you are confident about what an API is and, for the brave, could actually take a stab at using one.

This text is about the dangers of man-in-the-middle attacks on browsers, especially in the scenario of open or rogue wifi networks. The scenario I'm assuming here is something like this:

You are travelling.
You have your notebook/smartphone/... with you.
You don't have an internet connection.
There is an open wifi that you could use.
You just want to check the news.
Maybe you also want to check your webmail or so (over SSL, of course)
Your browser and the plugins in it are fully patched and there's nobody who would attack you with an 0day and has one.
Your browser executes Javascript (by default). (Some of the attacks are possible without that, but the really scary stuff isn't.)

Given this scenario, what could go wrong?
I will show that an attacker could probably effectively gain code execution access to your machine in the long term.
