Botnet attacks exploit a command-and-control model, enabling hackers to control infected devices, often referred to as “zombie bots,” remotely. The strength of such an attack depends on the number of devices compromised by the hacker’s malware, making botnets a potent tool for large-scale cyberattacks.
Any device connected to the internet is at risk of becoming part of a botnet, especially if it lacks regular antivirus updates. According to CSO Online, botnets represent one of the most significant and rapidly growing cybersecurity threats. In the first half of 2022 alone, researchers detected 67 million botnet connections originating from over 600,000 unique IP addresses.
Botnet attacks typically involve compromising everyday devices like smartphones, smart thermostats, and webcams, giving attackers access to thousands of devices without the owners’ knowledge. Once compromised, these devices can be used to launch spam campaigns, steal sensitive data, or execute Distributed Denial of Service (DDoS) attacks. The infamous Mirai botnet attack in October 2016 demonstrated the devastating potential of botnets, temporarily taking down major websites such as Twitter, CNN, Reddit, and Netflix by exploiting vulnerabilities in IoT devices.
The Lifecycle of a Botnet
Botnets are created through a structured process that typically involves five key steps:
