However, the courier has to pass a security scanner before entering the facility. This is a novel scanner, using an extremely powerful, ultra-short magnetic pulse that renders a high-quality image of the person and all he carries, without harming the person.
What the scanner also does is erase the memory card in his briefcase. This decades-old card was not designed for such a high field.

General: “Get a tap on their Internet lines.”

Then it hits. A massive coronal mass ejection from the sun. Everything electronic shorts out immediately, unusable. Everything else metallic that attenuates electromagnetic waves quickly overheats, melts, and fuses. The entire societal infrastructure is lost.

Technician: “Oh God, what have you all done?”

Hardened by 2015's vicious disputes and coddled by a year of New Anonymity, citizens factionalize as a defense mechanism against the horrors that they know their evil opponents can't wait to unleash on them. Since people can no longer acquire the necessities of daily life anonymously, they are forced to reveal their identities, needs, and resources to trade for sustenance. This unmasking, sharing, this shameful "nakedness" before others is inimical to the paranoid way of life
politicians and citizens enjoyed for a year, and with no infrastructure left to go back to the old ways, society degrades. The larger factions break up as members realize others disagreed on some litmus test issue from the past, and familial tribalism takes hold.


NS: Neither of those sir. Even worse...

They manage to uncover the plot through the use of their complementary abilities, but they violate the privacy protection laws in the process. The FBI throws them in jail and the conspiracy continues.

The year is 2020. Following calls to ban all encryption in 2015 and 2016 and the subsequent realization that this would severely damage the global economy in 2017, a massive internet crash was caused by malevolent North Korean hackers exploiting the newly found 0-day vulnerability dubbed “SNEAKSEIZURE”, requiring the whole internet to be rebooted and North Korea to be nuked by China, a huge loss of face for the communist turned capitalist state.

The cryptothief: teens and cryptography. It can only end badly.

Under the new Nine Eyes (the Five Eyes plus Russia, South Africa, China, and Germany) Consortium’s supervision, special software has been made mandatory for everyone. Baked into the EFI BIOS of every new computer, it allows access to the revitalised internet. Older systems are unable to access this new internet, lacking support for the new ultra high speed tech supporting IPv.7 standard. This software supports special cryptographic techniques developed by MICIVES (Military Intelligence against Cyber Insurgency Vying for Extreme Secrecy - the replacement for the NSA) that allow denizens to securely access only those services that are deemed acceptable by the authorities and the major technology companies, while also providing access to all personal data desired by the authorities. Now and then, MICIVES sentences an evil cryptographer to forced labor in the data centers of Amazon, with TV reports showing the evils of cryptography (child abuse, drug abuse, murder, sexual deviancy, and facial features typical of a criminal - beard, wonky, looks tired and bleak) to the aprehensive public, likening the effects of cryptography to that of Kryptonite on Superman.

Fade to black as they realize they can no longer breed.

The remaining old folks, who still yearn for New Anonymity after scraping together enough food to survive for 40 years have had enough. They recall stories of "pen and paper ciphers" from the before time, before they needed the machines to protect them. One strikes out on a quest to learn the old ways, discovering an old book describing "the Caesar Cipher", and sees an opportunity.

Set in the not-so-distance future...

The American culture wars of 2015 took a severe toll, leaving all but the most antisocial identifying more strongly as a member of a group than as individuals. Corporations, emboldened by government submission to their boycott and counter-boycott fueled demands, sense an opportunity and implement strong encryption across all consumer devices to capitalize on the citizenry's distrust for one another. Politicians jump on this and both major parties make efforts to outcompete the other in
pandering to those demanding New Anonymity.

POTUS: What the f--- are we paying the NSA for? Can’t they crack it!

Confident in their secure communications, the Caesarpunks walk openly in the new world, while conspiring secretly. On the appointed day, they salt the fields, raze the communal living areas, and exterminate the shameful young.
