"Hacking Blockchain with Smart Contracts to Control a Botnet"

Security researcher, Majid Malaika, has warned of the possible abuse of Blockchain technology to enable the creation of a powerful new form of botnet. The attack method that has been named “Botract”, abuses code that runs on a blockchain known as a smart contract. A smart contract that is specifically written to allow the command and control for a botnet would significantly increase the resiliency of the botnet application. This article further discusses how Botract works, the flaw within the blockchain smart contract model that enables this attack method to work, and the purpose of this research.
