We hear plenty of stories about hackers getting into computer systems and devices—viruses, man-in-the-middle attacks, DDos storms, malware, ransomware and the like. But would you believe the first electronic hack happened in 1903? Guglielmo Marconi, the father of modern radio, had come up with the concept of point-to-point wireless radio transmissions.
“By tuning a transmitter to a specific frequency,” he said, “you can securely reach another party who has tuned to exactly the same frequency.”
This greatly annoyed telegraph companies, who didn’t want to be put out of business. One of these telegraph operators, a guy named Nevil Maskelyne, heard about a demonstration Marconi was giving. Using his own transmitter, he hacked into Marconi’s test broadcast, spelling out the word “rats” over and over in Morse code. Then he keyed in a rude limerick that began “There was a young fellow from Italy, who diddled the public quite prettily.”
I guess this makes Maskelyne the first-ever black hat hacker.
