It's time to publish the first timeline of April covering the main cyber attacks occurred between April 1st and April…
For the Infosec professionals, this troubled 2014 will be remembered for the trail of gigantic breaches unleashed nearly exactly one year ago, when the real outcome of the infamous Target breach became to emerge. The real extent of the breach was yet to be known, like also the fact that it would not have been an isolated case, but just the beginning of a nightmare.
However this is not the only example of a Fortune 500 company deeply hit, and thanks to a very smart hint by @bufferzone, I took the opportunity to collect in this timeline all the main cyber incidents involving Fortune 500 and Fortune 500 Global companies since 2011 to nowadays.
The adopted selection criteria take into considerations only incidents involving a direct impact on end users, so defacements have not been taken into consideration.
Fortune 500 Global companies are characterized by a blank value in the Rank column, whereas Fortune 500 companies are characterized by a red value. Also, when possible I inserted both values if the targeted company belongs to both charts and, in those cases in which a subsidiary company has been targeted, I have obviously inserted the rank of the parent company.
