“Design and Implementation of Machine Learning Algorithms for Web Cryptomining Detection” In the last years, cryptocurrencies like Bitcoin, Monero and Ethereum have gained popularity since they provide a valid alternative to the centralized banking system and an advantageous context for financial speculation. A core part in the cryptocurrency structure is the mining process, in which a computationally heavy cryptographic problem has to be solved in order to validate a group of online transactions and generate new currency. As this mechanism establishes a reward for each problem correctly solved, some ill-intentioned users, in place of using their own machines, started to make website visitors silently running some cryptomining code on their devices, creating as a matter of fact a new source of profit.
