You might have already heard about how github got hacked during the course of a discussion about safer defaults regarding the mass assignment vulnerability.
In my new blog post I talk a bit about what happened there, what this vulnerability is and how to protect against it. I also point the reader to further security resources like the Ruby on Rails security guide and the brakeman vulnerability scanner.
As security is always of the utmost importance and with the number of "hackers" trying to exploit this vulnerability probably rising, as it is all over the news, I highly encourage you to read it if you feel unsure about your knowledge of the mass assignment vulnerability.
