How the first ever telecoms scam worked

In the 1830s, two French brothers, François and Joseph Blanc, pulled off the first telecoms scam in history. The optical telegraph, a line of semaphore towers stretching from hilltop to hilltop, was for government use only: but something as simple as the law wasn't going to get in their way.

Alexandre Dumas' _The Count of Monte Cristo_ includes an episode where the count ruins one of his adversaries by sending a false message about the stock market through the telegraph system. Published in 1844 it was about a decade after the escapade by the brothers Blanc. No doubt Dumas was inspired by the story when it came out.

The earlier story that used the towers for its plot was Count Of Monte Cristo by Alexander Dumas.

[@timothymclean]

The idea of banning private semaphore towers, without providing any public alternatives, probably made perfect sense in the 19th century; nobody knew what that sort of rapid communication network could do for the civilian sector that would be worth anything. (Of course, the low bandwidth limits what could be done with it, but there were absolutely still possibilities.) To someone in the 21st century, that idea sounds ludicrous; we've built so much on a publically-available high-speed communication system that we can't imagine anyone being so foolish as to throw all that aside.

[@davidweihe6052]

The British had semaphore telegraph system during the Revolutionary and Napoleonic Wars, although I think that they were abandoned afterwards. Signalling as far as can be seen fails badly in fog or rain, even with telescopes, and so was not felt worth the trouble and expense over sending riders, since there was felt to be no chance of missing an invasion.

In The Count of Monte Cristo, the Count abused the French semaphore network to make false news that financially crippled one of his old rivals.

For some reason, I have a version where the count sets one of the rivals up to be kidnapped and forced to pay back all the money that the rival had just taken, but the count does the actual kidnapping.

As a French person I always thought everyone knew about the semaphores... Well, apparently that's not true.

[@russcrawford3310]

Thank you mama Victoria ... we all love you ...

[@michaelhunt6019]

I find your titles and topics seemingly mundane and yet, you never disappoint in your depth and breadth of knowledge. You connect the dots and let me see the whole picture. Thank you Tom.

The scam sounds like something you could do to mop up data on an unencrypted network. I wish I knew more about the subject to articulate what I'm actually thinking of...

[@atianfirebolt8125]

Any unencrypted data isn't worth your time.

[@Chartreugz]

@Atian Firebolt Not necessarily true, even metadata like "who is sending signals and at what times?" or "When is the highest volume of messages in a day?" can be important.

Naomi PR indeed even ‘crumbs from the table’ can tell you what was being eaten for dinner...

My local police radio signals are unencrypted and i can tell you they are quite interesting to listen to.

[@jlammetje]

There are actually exploits that sort of use this principle. A type of virus that will send instructions (send “wrong symbol”), knowing they will not be carried out (backspace, sorry, left out of transcript), because the side effect will still be there (signal was sent, just not written down in the transcript). It’s not an exact match, but it reminded me of that. I can’t remember the name of the virus though. Targets certain kinds of processors

Gorgeous video, dear Tom!

This is an absolutely fascinating story. Really one of the best I've seen.

[@gregwilmot3260]

You said 18th century france when in fact it took place in 1830s. This would be the 19th century.

[@durhamdavesbg4948]

As in the semaphore system was built in the late 18th century.

I really appreciate how much time and effort you seem to put into your videos. They are always very interesting and I just wish the world had more Toms so we could get more videos like this one! I am very thankful for the one Tom and all of his crew we have the privilege of being entertained by, though. Thank you!

[@vkoskiv]

So much info packed into this short video. I want to watch it again now!

[@rashkavar]

It's probably worth noting that speed of information flow has been an issue basically since people started using stock exchanges as a significant income generator, as has decision making. When it was a building full of physical people and you had to get info published, having your office next door was beneficial so you could have an employee sit there and listen to things and report back when interesting stuff happened. Better yet, be there yourself. (Personally I'd argue that these people are lunatics and short term analysis suffers from a major problem with signal to noise ratio, and that it's far more advisable to make long term investments in businesses that you can reasonably project will be profitable over the next few years, especially if they pay dividends, because being paid to own your investment is better than not being paid to own something.)

Liked just for the amount of work put into making sure this is correct info.
