A running intercept log of telecommunications history — signaling vulnerabilities (SS7, Diameter, GTP, BGP), subsea ocean cables, and nation-state cyber espionage, indexed from the 1837 optical telegraph to the 5G/6G core.
Francois and Joseph Blanc hijacked the French optical telegraph network by bribing operators to insert deliberate backspace/error codes into stock market transmissions. The scheme ran for roughly two years before being exposed in 1836, making it the first documented attack combining an insider, a covert channel, and a financial network.
Samuel Morse transmitted the first message ("What hath God wrought") over the Baltimore–Washington line on May 24, 1844, exposing physical wiretapping along unencrypted DC lines almost immediately.
John & Jacob Brett laid the first subsea cable across the English Channel between Dover and Calais, connecting the British and French telegraph networks on August 28, 1850.
On 17 May 1865, after a conference running from 1 March, twenty European states signed the first International Telegraph Convention in Paris and created the International Telegraph Union — the body that became today's ITU.
After the 1858 cable died within weeks and the 1865 attempt snapped mid-ocean, SS Great Eastern left Valentia on 13 July 1866 and spliced the cable ashore at Heart's Content, Newfoundland, on 27 July 1866 — the first durable transatlantic link. The lost 1865 cable was grappled up and completed that September.
Alexander Graham Bell was granted US Patent 174,465 for the telephone, introducing analog voice circuits that immediately opened new attack surfaces for inductive and galvanic eavesdropping.
Undertaker Almon Strowger patented the first automated stepping switch after suspecting manual telephone operators were diverting his business calls to a competing undertaker.
Illusionist and wireless pioneer Nevil Maskelyne intercepted and injected sarcastic Morse code insulting Guglielmo Marconi during a live demonstration at the Royal Institution in London, proving that open radio channels lacked origin authentication.
