I am quite in time with the list of the main Cyber Attacks occurred in the first half of July.
This period has been quite hard for the Video Games Industry with two noticeable events targeting Konami and Ubisoft (58 million of account potentially affected in this second case). Another noticeable breach involves the attack against the Italian Website of Sony, which lead to 40,000 records leaked.
Regarding hacktivism, Turkey keeps on being quite hot in this period, and not only for the Summer: several governmental targets have been hits by cyber attacks directly related to the OpTurkey initiative.
Last but not least: you will notice I have added a new column indicating the target country: for the sake of clarity, it refers to the nationality of the targeted organization and not to the geo-location of the targeted IP.
As usual, 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, 2012 and now 2013 (regularly updated). You may also want to have a look at the Cyber Attack Statistics, 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).
