Firstly, a huge thank you to Neil Smith for sharing his technical and historical knowledge of “The Thing” and operation Easy Chair. These devices are crazy complicated! And Neil (given that he’s actually built a working replica of “The Thing!”) gave invaluable insight into how it works, and detailed feedback on early versions of the video. You can see even a more detailed explanation of “The Thing” from Neil here – "Leon Theremin Changed Spying FOREVER with this 1940s invention!", on his channel: @MachiningandMicrowaves Thanks to R. Paul Wilson for a comprehensive overview of the potential ways that credit cards and contactless payments can be compromised, and for connecting us with Christopher Forte. A big thank you to Christopher for his technical advice on different attack vectors for NFC transactions, his insights into the “cat and mouse game” between hackers and security providers, and feedback on different parts of the video. Thanks to Pavel Zhovner, CEO of Flipper Devices, for talking us through the various security layers in NFC transactions, showing us round the Flipper HQ, and even giving us several Flippers to experiment and film with! Thanks as well to Tony Sales, for his candid – and thoroughly entertaining(!) – recounts of credit card vulnerabilities, and explaining the work he does today in testing them. Thanks to @mkbhd and his team for filming all the different demo’s with us – and of course, putting himself forward for the hack we’ll cover in part 2 of this video! And last but definitely not least, a big thank you to professors Tom Chothia and Ioana Boureanu, for their technical support on the video, and of course, talking us through in great detail and even lending us the equipment for the hack we’ll be attempting in part 2! ▀▀▀ References: https://ve42.co/Spies&CardsRefs ▀▀▀ Special thanks to our Patreon supporters: Adam Foreman, Albert Wenger, Alex Porter, Alexander Tamas, André Powell, Anton Ragin, armedtoe, Balkrishna Heroor, Bertrand Serlet, Blake Byers, Bruce, Charles Ian Norman Venn, Daniel Martins, Data Don, Dave Kircher, David Johnston, David Tseng, EJ Alexandra, Evgeny Skvortsov, Garrett Mueller, Gnare, Hayden Christensen, Hong Thai Le, Ibby Hadeed, Jeromy Johnson, Jesse Brandsoy, Jon Jamison, Juan Benet, Kelcey Steele, KeyWestr, Kyi, Lee Redden, Marinus Kuivenhoven, Mark Heising, Martin Paull, Meekay, meg noah, Michael Krugman, Moebiusol - Cristian, Orlando Bassotto, Parsee Health, Paul Peijzel, Richard Sundvall, Robson, Sam Lutfi, Shalva Bukia, Sinan Taifour, Tj Steyn, Ubiquity Ventures, Vahe Andonians, wolfee ▀▀▀ Writers: James Moore, Casper Mebius & Henry van Dyck Producer & Director: James Moore Presenters: Derek Muller & Henry van Dyck Editor: Peter Nelson Animators: Andrew Neet, Domonkos Józsa, Alex Drakoulis & Mike Radjabov Illustrator: Jakub Misiek Assistant Writers: Aakash Singh Bagga & Darius Garewal Assistant Editor: James Stuart Researchers: Aakash Singh Bagga, Darius Garewal & Callum Cuttle Camera Operators: Andrew Abballe, Henry van Dyck, Gregor Čavlović & Andy Perez Thumbnail Designers: Abdallah Rabah, Ren Hurley & Ben Powell Production Team: Jess Bishop-Laggett, Matthew Cavanagh, Anna Milkovic & Sulli Yost Executive Producers: Derek Muller & Casper Mebius Additional video/photos supplied by Getty Images & Storyblocks Music from Epidemic Sound
