Here's the second timeline of April (first part here) covering the main cyber attacks occurred between 16 and 30 April…
Apparently October has shown a decrease in the number of Cyber Attacks. At least from a mere numerical perspective. It is not a coincidence that I used the term “Apparently” since if we consider the most important event of the month: the massive leak from Worldwide universities executed by Team GhostShell inside their ProjectWestWind operation, things are well different.
The one carried on by Team Ghost Shell (approximately 120k accounts leaked) is for sure the most important operation of the current month which has also shown the first virtual hacking operation (at least as far as I remember): the massive death of avatars inside World of Warcraft.
Other remarkable events in the first half of October concern the attack to Playspan (possibly millions of users affected), the new waves of DDoS cyber attacks against US banks, and an alleged hijacking to the Irish domains of Google and Yahoo!.
It worth to mention also the breach of University of Georgia (8,500 users affected) and the 400,000 bucks stolen by unknown hackers to the City of Burlington.
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 and the related statistics (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).
