i finally got that stupid "worm"

Sooo...that nation wide power outage. Is that the "worm" that did that? I know it was hackers but how did they do it?

it was NOT,

Something happened at a power-transmission line in suburban Cleveland, and that set off a chain of events that led to the blackout, ABCNEWS has learned.

remember those electrical stuff is about 50 years old, it was bound to brake !!
