+overview

Smart contracts have have come a very long way since 1994 when Nick Szabo originally coined and imagined what they could be used for until the present day where smart contracts running on various blockchains such as Ethereum are now transacting and processing billions of dollars a day.

One of the key benefits of smart contracts is that they are forever immutable. Once a smart contract is deployed on a public blockchain, it is almost immediately available to all participants on that blockchain to interact with, send value to and receive value from. It can not be deleted, it can not be changed, it can not be "taken down" and removed like ordinary content on the Internet can.

A smart contract is anonymous. Of the millions of smart contracts that have been deployed until now, its fairly impossible for anyone to know unless explicitly published and associated with a corporate entity or individual who that smart contract belongs to. You could deploy a smart contract right now and nobody would be able to attribute it to you.

Communicating with a smart contract is also anonymous. You could send commands to a smart contract and nobody would be able to tell who initiated those commands, their IP address and where in the world they are situated.

Do these qualities sound like the perfect ingredients to build a fully anonymous rootkit C2 infrastructure? That's because they are.

In this talk, we will create a smart contract with rootkit functionality. Any device that monitors the smart contract can be remotely controlled at will including mobile phones, IOT devices, servers and PCs. You could connect a whole botnet to a single smart contract and control a swarm of infected machines at scale and with minimal cost or you could control a single high value target anonymously and without fear of retribution or attribution.

I will demo a smart contract powered rootkit live.
