When was the world's first documented cyber attack on a data network?

Woah!! Nobody knew that.

cyber- a combining form meaning “computer,” “computer network,” or “virtual reality,” used in the formation of compound words (cybertalk; cyberart; cyberspace) and by extensionmeaning “expressing visions of the future” (cyberfashion).

Arjit Sharma, I didnt know that and it put me in shock!!

WOW that would have been my last choice. that is very interesting though

what type of data breach could have happened I. 1834?
