Botnet
Botnets are networks of hijacked computers or IoT devices controlled remotely by attackers to run automated tasks like spam floods, DDoS attacks, and credential theft. The word became widely known through cases like the 2007 Storm Worm and the 2016 Mirai attack that briefly knocked major sites offline.
Overview
A botnet is a network of internet-connected machines secretly compromised by malware and controlled by a single operator to run automated tasks like sending spam, launching DDoS attacks, or harvesting credentials3. In hacker slang, individual infected devices are called "zombies," and the operator directs them remotely, historically through IRC channels or dedicated command and control servers4.
The word botnet also became internet shorthand for anything sketchy that quietly phones home to a central operator, including jokes about Windows 10 telemetry or free VPN apps that resell users' bandwidth4. Threat researchers have tracked dozens of major botnets since the mid-2000s, and names like Storm, Zeus, and Mirai are still widely referenced in security circles.

How to Use This Meme
Outside of security papers, people often use "botnet" loosely online to accuse any piece of software of being creepy or spyware-like, common convention being to sarcastically label heavy telemetry, background analytics, or free tools that mine user data as "literally a botnet"4. In technical contexts, the word typically refers to a specific tracked family such as Mirai variants, Emotet, or Zeus descendants.
