Here is the list of the main Cyber Attacks happened during the second half of February 2014 (Part I here). As you will soon discover, unlike the previous months, the activity in this second half of February has shown a sensible decrease both in number and in size in comparison with the previous months.
One of the few exception to this decreasing trend is the University of Maryland, that was the victim of a cyber attack that led to the compromising of more than 300,o00 records.
Apparently even the hacktivists have slowed down their attacks with few exceptions (the Syrian Electronic Army and some sporadic actions executed by hackers affiliated to Anonymous.
Interestingly the cyber espionage front has been the more interesting with a couple of remarkable events (a cyber attack against a French aerospace engine maker and the revelation of further details concerning the Iranian attack against a US Navy Computer Network.
