There are many types of bots on the Internet that serve a wide variety of purposes. Bots can be categorized into three main types:
good bots, grey bots, and malicious bots.
Types of 'GOOD' Bots
Good bots are designed to perform useful and legitimate tasks that benefit users and website owners. Some examples include:
- Search Engine Crawlers: These bots index web pages for search engines like Google and Bing, helping users find relevant information quickly. While good, It is still very important to control these in your robots.txt file to prevent them from over crawling your site.
- Monitoring Bots: They monitor websites for performance, uptime, and security issues, alerting administrators to any problems.
- Customer Service Bots: These chatbots assist users with common queries, providing instant support and improving user experience.
- Social Media Bots: Bots like Twitter feed bots share news updates or content automatically, helping users stay informed.
Types of 'Grey' Bots
Grey bots operate in a legal and ethical grey area. They may not be explicitly harmful, but their activities can be considered intrusive or borderline unethical. Examples include:
- Research Bots: These bots extract data from websites, such as prices, reviews, or content. While some scraping is legitimate, excessive or unauthorized scraping can strain server resources and violate terms of service.
- SEO Bots: They automate tasks like link building or content generation to improve search engine rankings. If used excessively, they can be seen as manipulative.
- Aggregator Bots: These bots collect content from various sources and republish it. While they can provide valuable services, they may also infringe on content creators' rights if not done properly.
- LLM Scraping Bots: Large Language Model (LLM) training bots are now scouring the internet for training material for AI.
Types of 'Malicious' bots
Malicious bots are designed to perform harmful activities, often for personal gain or to disrupt services. Some common types include:
- Spam Bots: These bots post spam comments or messages on forums, social media, and websites, often promoting products or phishing links.
- DDoS Bots: Distributed Denial of Service (DDoS) bots flood websites with traffic, overwhelming servers and causing them to crash, rendering services unavailable to legitimate users.
- Credential Stuffing Bots: These bots use stolen credentials to gain unauthorized access to user accounts, often leading to data breaches and fraud.
- Ad Fraud Bots: They generate fake clicks or impressions on online advertisements, draining advertisers' budgets and skewing analytics.
- Malware Bots: These bots spread malware, infecting systems to steal data, encrypt files for ransom, or create botnets for further attacks.
- Vulnerability Scanners: These bots scan websites for security vulnerabilities that can be exploited, such as outdated software or misconfigured servers.
- Card Cracking Bots: These bots use automated techniques to test combinations of payment card details, attempting to find valid combinations for fraudulent transactions.
- Inventory Hoarding Bots: These bots purchase large quantities of in-demand items, such as event tickets or limited-edition products, to resell at a higher price.
- Scraping Bots for Competitive Intelligence: These bots gather competitive data illicitly, such as pricing strategies, product details, and customer reviews, to gain an unfair market advantage.
- Sneaker Bots: These bots are used to purchase tickets or goods in time restricted sales. Since they operate much faster than humans they can snap up items before humans can.
Understanding the different types of bots on the internet helps website owners and users recognise the potential benefits and threats they pose. By employing appropriate security measures, it is possible to mitigate the risks associated with malicious bots while allowing beneficial bots to perform their tasks effectively.
