The correct answer is 'Botnet' because it describes a network of compromised computers that are controlled remotely, typically without the owners' knowledge, to perform tasks such as cryptocurrency mining. A botnet infection matches the scenario described where multiple endpoints are being remotely controlled. A Ransomware infection would generally encrypt files and demand payment, which is not mentioned in the scenario. A Logic Bomb would execute malicious code based on certain conditions being met, which is not indicated in this scenario. A Worm would self-replicate to spread to other computers, but it does not inherently control multiple endpoints for a task like cryptocurrency mining.
