DefinitionA bot (ボット) is malware that lets an attacker remotely control an infected computer from outside.
ExplanationAn infected device waits for orders from a command server (指令サーバ) set up by the attacker and acts on them once they arrive. A group of many infected devices driven by the same orders is called a botnet (ボットネット); because botnets are used for mass attacks on a particular site (DDoS attacks, DDoS攻撃) and for sending spam in bulk, the infected side ends up taking part in the attack without realizing it.
