What are potential indicators that a mobile device is part of a botnet? (Select the two best answers.)

High resource usage is a strong indicator that a mobile device might be part of a botnet. When a device is infected and controlled as part of a botnet, it can experience increased CPU and memory usage due to processes running in the background that the user isn't aware of. These processes could be related to sending out spam, participating in DDoS attacks, or other malicious activities. Users might notice this as a sluggish performance, apps taking longer to load, or overheating due to the increased computational demands.

In addition to high resource usage, significant power drain can also indicate botnet activity. When a device is part of a botnet, it may be continuously active, consuming more power than usual due to the additional tasks it is performing. If a user notices their device's battery depleting much faster than normal, it could be a sign of malware running in the background.

Understanding these indicators helps in identifying compromised devices quickly, allowing for appropriate action to secure them and mitigate further issues.
