This month will be probably remembered for the Home Depot breach. Yet another one caused by the same POS malware family that hit Target, with a similar dramatic extension: unfortunately the retailer believes that 56 million of credit cards could have been compromised in this case. After such a similar gigantic breach there is not so much to add as far as Cyber Crime is concerned, as it overshadowed all the rest.
In regards of Hacktivism, this has been a terrible month for Pakistan, which has attracted the unwelcome attentions of hacktivists protesting against the corruption of the government. As a consequence dozens of government sites have been bombarded with DDOS attacks, (with few cases of defacements and leaks).
Nothing particularly important to mention for Cyber Espionage. After the spree of the past months, maybe is time for a break.
If you want to have an idea of how fragile our electronic identity is inside the cyberspace, have a look at the timelines of the main Cyber Attacks in 2011, 2012, 2013 and now 2014 (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).
