Here we are with the second part of the timeline of May (first part here).

Summer is coming here, and looks like attackers prefer to spend more  time in the beach rather than in front of their keyboards. In fact the number of reported attack is confirming its decreasing trend, at least for this part of the year.

Nonetheless, the second part of may has brought some noticeable events, such as the attack to Ebay (potentially 145 million accounts compromised), the attack against the Avast! Forum (400,000 records compromised) and the Arkansas State University (“only” 50,000 records). Other noticeable (and funny) event includes the hack of a San Francisco road sign by a prankster announcing the attack by Godzilla!

Cyber Spies were indeed pretty active in this period. Chronicles report of the Operation Clandestine Fox, a cyber attack against several industries in Australia, an undisclosed utility attacked in the US, a three year social network poisoning campaign sponsored by Iran and, last but not least, the alleged attack against the $12.7 million supercomputer in New Zealand from Chinese attackers.

Instead the operations from Law Enforcement Agencies against Hacktivists seem to be effective, the number of attacks motivated by hacktivism is dramatically reducing.

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).
