While I really feel badly for the person this happened to, I think we should stop expecting Amazon to foot the bill for these kinds of things. If I buy a new car and then leave the key sitting on the hood, I don't ask the car dealer to reimburse me when it gets stolen. Let's remember that Amazon is being incredibly generous by reimbursing users for these problems, but they should certainly not be expected to do so.
That is why AWS has billing alerts that will send you an email or text if you reach a predefined spending threshold. I had some trouble to find at first on their website so maybe it should be more visible.<p>The cool thing with Amazon is that they definitely pay attention to your opinion as a consumer. A few months ago, I sent an email to Jeff Bezos to complain about the Amazon Locker interface that I found cumbersome - it used to show you all lockers including the full ones and there was no way to see which ones you can actually deliver to - and his assistant answered and let me know that my message was forwarded to the appropriate team. They changed the interface a few weeks later. Maybe the author of this post should do the same.

I've spent a large amount of time fending of bitcoin miners from abusing my site <a href="https://cloud.sagemath.com" rel="nofollow">https://cloud.sagemath.com</a>. I like the mathematics and promise of bitcoin, but in practice it is an enormous waste of resources (time, electricity, etc.).
Amazon support is pretty good so you might be in luck and not get billed, especially since you caught it quick. I am sure you aren't the only person who was compromises like this.
I also saw this in the wild today on a friend's aws account. Same instance size. Spot at $2. Just one instance fortunately.<p>The security group permitted SSH from three /24 netblocks.
I'm surprised that it was large instances instead of GPU instances. GPU would be much more profitable if you are mining a scrypt coin (or sha256 coin but that would be stupid because of ASICs).<p>Maybe it was some other type of coin (I'm not sure if primecoin is more CPU-friendly).
You drive in a city at night and see all these office floors fully lit, and you wonder how many employees are having their office computers on mining bitcoins?
