But the history of cyber attack goes further than the Morris worm.
What existed instead was a large data data pipe based on optical telegraphy called the semaphore.
Different configurations of these arms corresponded to different letters, numbers and symbols.
This way a message could be transmitted from station to station and along the line at a remarkable speed.
Some tried using messengers and carrier pigeons, but the Blanc brothers knew they were not reliable.
Pigeons often got lost, and messenger werent necessarily faster than the mail coaches.
They figured out another way to do it.
The telegraph operators job was to transmit that news from Tours to Bordeaux using the semaphore system.
Normally, when an operator made innocent mistakes in signaling, he wouldencode a correctionin a subsequent transmission.
Both the error and its correction would then be duplicated from station to station.
Once the end station had received both the fault signal and the correction, the error would be corrected.
He would read the errors, translate it and relay the news to the Blancs.
Unfortunately for him, his friend had a clearer conscience and reported the operator to the authorities.
A strong email password is useless if you write it down and keep it in your wallet.
In the case of the Blancs, it was corruption of the telegraph employees.
