Unpacking ASIC firmware: AntMiner Exploited

Introduction Experts say cryptocurrencies (such as Bitcoin, Monero, and Ethereum) will be the protagonists of the future decentralized and distributed economic system. If this is true then one of the most debated topics in the field of cryptocurrency, how to verify payments while spending as little as possible in terms of resources, is especially important for cryptosecurity. There are many verification methods. “Proof of Work” is an easy verification method to execute yet it’s extremely difficult to create. Once the miner has received transactions, they solve a math puzzle in order to add the new block to the blockchain. Since this task necessitates a lot of resources, both economically (energy bills) and technically (CPU, RAM..), advantages arise from building a specific circuit used to circumvent these costs. An application specific integrated circuit (ASIC) is an integrated circuit created to solve a very specific calculation. A given example could be the Bitcoin ASIC w
