Update June 4 2012: May 2012 Cyber Attacks Timeline (Part II)
As usual here it is the timeline of the Main Cyber Attacks occurred in May (at least according to my evaluation criteria).
This first half of the month has seen the arrival of a new hacking collective, “The Unknowns”, who has performed an impressive trail of attacks during the first days of May, targeting Space Agencies, Universities, and several other organizations. Although these events appear to be closer to cyber crime actions rather than hactivistim-driven attacks, they have not been the most remarkable ones of these days: as a matter of fact chronicles report of a massive breach at the Hangzhou Dianzi University, targeting approximately 150.000 acccounts.
As far as hacktivism is concerned, this first half of May has confirmed the constant trend of DDoS attacks targeting high profile websites such as SOCA and CIA (once again) and the Supreme Court in retaliation for the U.K. extradition laws.
Interesting to mention is also an alleged Cyber Espionage campaign targeting networks belonging to US natural gas pipeline companies.
