A botnet operates in cyberattacks by utilizing a network of infected devices (bots) that are remotely controlled by attackers. Each bot executes commands issued by the attacker, often without the owner’s knowledge. Common malicious activities include DDoS attacks, where a coordinated surge of traffic overwhelms a target server, rendering it inoperable. These attacks exploit vulnerabilities across several devices, amplifying the attack's impact. Botnets are typically created using malware that infects and compromises connected devices, perpetuating the cycle of attack.
