Crypto-Crash

In the mid 21st century, a Swiss cyber-security firm tasked with countering ransomware attacks on major financial institutions exposes a Russian criminal gang supported by a top North Korean hacker. This leads to the discovery of a much more dangerous plot to destroy economic databases, aimed at causing chaos on a global scale. The defence against this threat requires extending the abilities of neural networks run on an advanced quantum computer, creating a form of artificial intelligence which can compromise the cryptography forming the basis of the security of both computer networks and electronic communication.
Not only does this tool exceed expectations, it opens a Pandora's Box of other possible applications that could risk destruction of civil liberties and the entire basis of free democracies. The team use this tool to combat threats from China, the USA and also criminal organisations who are competing to gain control of such power. Inevitably, this leads to inflicting punishments that are comparable with the impacts of conventional warfare.
Recognising the dangers of wider access to this technological singularity, they decide to actively limit further developments in this direction elsewhere so that, for the near future, this small group are reluctantly placed in the position of a global oligarchy - with all the responsibilities and dangers that this entails.
