While surfing today, I came across this article about showing a world map and the various successful confirmed attacks against the USA power grid. The media might have you believing that cyber terrorism is an important threat vector. Maybe in the future it will be, but according to this data, looks like squirrel attacks are the more imminent threat.
To recreate my graphic, goto http://cybersquirrel1.com and select “squirrel” from the first drop-down, 2015 from the second drop-down, and October (e.g. 10) from the third drop-down. Obviously, you can select other times and “other animals” if you want to see other data. Note that the reason I focused upon the USA is that data is more extensive. In contrast, the German data indicates “animal attacks” but does not indicate the type of animal perpetrator.
If you click on any of the red marks on the map, a popup will show you more detailed information about that particular event. Enjoy!
