Bot automation is the use of software-driven accounts or workflows to perform actions automatically and at scale. A bot can post messages, join groups, send requests, collect data, or trigger other system events without direct human input. In messaging platforms and other online services, bots are often built for legitimate tasks such as notifications, support, and moderation.
In cyber security, bot automation matters because the same efficiency can be abused. Attackers use automated accounts for spam, credential stuffing, phishing distribution, fake engagement, scraping, and rapid account creation. Automation can also help defenders by filtering abuse, flagging suspicious behavior, and enforcing policy faster than manual review alone. Security teams watch for bot-like patterns such as repetitive timing, high-volume actions, and identical content across many accounts. Controlling bot automation usually requires rate limits, reputation checks, abuse detection, and strong authentication for privileged bots.
