As usual, here is the list of the main cyber attacks for April 2012. A first half of the month which has been characterized by hacktivism, although the time of the resounding attacks seems so far away. Also because, after the arrest of Sabu, the law enforcement agencies (which also were targeted during this month, most of all in UK), made two further arrests of alleged hackers affiliated to the Anonymous Collective: W0rmer, member of CabinCr3w, and two possible members of the infamous collective @TeaMp0isoN.
This infamous 2011 is nearly gone and here it is the last post for this year concerning the 2011 Cyber Attacks Timeline. As you will soon see from an infosec perspective this month has been characterized by two main events: the LulzXmas with its terrible Stratfor hack (whose effects are still ongoing with the recent release of 860,000 accounts), and an unprecented wave of breaches in China which led to the dump of nearly 88 million of users for a theoretical cost of nearly $19 million (yes the Sony brech is close). For the rest an endless cyberwar between India and Pakistan, some hactivism and (unfortunately) the usual amounts of “minor” breaches and defacement. After the page break you find all the references.
