I wrote a small script to automate the parsing of the data collected in the Cyber Attacks Timelines. I am just verifying the data for January and February 2012 for which I did not publish any statistics. I was already able to classify the data for March 2012, whose results you can see in the Statistics page.
I also did a small exercise and tried to collect the distribution of targets for 2012. I know, I still miss the data of the first two months but I promise I will fill the gap very soon. In the meantime have a look at the graph and notice the impact of Cyber Crime. Of course the data for the single months can be viewed at the 2012 Cyber Attacks Statistics page.
If you want to have an idea of how fragile our data are inside the cyberspace, have a look at the timelines of the main Cyber Attacks in 2011 and 2012 (regularly updated), and follow @paulsparrows on Twitter for the latest updates.
Also, feel free to submit remarkable incidents that in your opinion deserve to be included in the timelines (and charts).
