The number of hacking events of late is making our heads spin at CNET. There were scores of computer attacks, network intrusions and data breaches in 2011 and the trend shows no signs of abating in 2012.

In previous coverage, we've noted that it seems to be open hacking season, written about some of the hackers and groups who are behind the attacks,and speculated on their motives, so we thought we'd provide a chronological chart listing the attacks so we could all keep up on them. We plan to update the chart as time goes on. So please let us know if there are any additions or changes that should be made.
