I landed the SSRF Cloud Metadata technique in a few different scenarios recently. If you haven’t seen the talk BHUSA 2014 - Bringing a Machete to the Amazon I recommend it.

To make life a little easier created a living URL list for Metadata broken down by cloud. There are a few more than he discusses in the talk but still has work to go. Submit a PR if you see some missing.
