Website bot detection is a getting more attention nowadays. Bots are software programs that perform automated tasks on the internet – and they can be useful or harmful, depending on their purpose and design. In this article, you will learn what bots do on the internet, how to detect a bot, and how they try to bypass detection measures. You will also discover some bot detection tools and techniques for online businesses.
What are bots?
Bots are software programs that perform automated tasks on the internet. They can be useful or harmful, depending on their purpose and design:
Useful bots are bots that perform beneficial or harmless tasks on the internet, such as searching and indexing web pages, interacting with users, or creating and distributing content. They can help users find information, access services, or enjoy entertainment. They can also help websites improve their performance, visibility, or functionality. Useful bots follow ethical and legal standards and respect the rules and policies of the websites they visit. Examples of useful bots are search engine bots, chatbots, content creation bots, etc.
Malicious bots are bots that perform harmful or illegal tasks on the internet, such as stealing data, spamming, hacking, or committing fraud. They can damage users’ privacy, security, or reputation. They can also harm websites’ functionality, quality, or revenue. Malicious bots ignore ethical and legal standards and violate the rules and policies of the websites they visit. Examples of malicious bots are spam bots, hacker bots, fraud bots, etc.
What can bots do?
Bots can do many things on the internet, such as:
Search and index web pages. These are the bots that help you find information on search engines like Bing or Google. They crawl and scan web pages, collect and store data, and rank them according to relevance and quality. Examples of these bots are Bingbot and Googlebot.
Interact with users. These are the bots that simulate human conversation and provide services or assistance to users. They can be found on websites, apps, or messaging platforms. Examples of these bots are chatbots, virtual assistants, and social bots.
Create and distribute content. These are the bots that generate and share content on the internet, such as articles, videos, images, or music. They can be used for entertainment, education, or marketing purposes. Examples of these bots are content creation bots, content curation bots, and content promotion bots.
Perform malicious activities. These are the bots that harm other users, websites, or systems on the internet. They can steal data, spam, hack, or commit fraud. Examples of these bots are scraper bots, spam bots, hacker bots, and fraud bots.
Are bots responsible for most of web traffic?
According to Statista, the global share of human and bot web traffic in 2022 was 52.6% for humans, 17.3% for good bots, and 30.2% for bad bots. This means that humans accounted for slightly more than half of the web traffic, while bots accounted for almost half of it. The share of bad bots was higher than the share of good bots, indicating a significant threat from malicious bot activity.
How to identify bots?
To protect their online platforms from bot-driven threats, many businesses use bot detection measures. Bot detection is the process of identifying and distinguishing between human users and bots, using various techniques and tools. Some of the common bot detection measures are:
Fingerprinting: Fingerprinting is the process of analyzing information to detect the software, network protocols, operating systems, or hardware devices from which a request originates. Fingerprinting can help identify bots that use specific tools or frameworks to mimic human behavior. However, fingerprinting can also be evaded by bots that use proxies, VPNs, or spoofing techniques to hide their identity.
Verification challenges: Verification challenges are problems that only humans can solve, such as CAPTCHAs or puzzles. Verification challenges can help filter out bots that cannot pass the test. However, verification challenges can also be bypassed by bots that use artificial intelligence, optical character recognition, or human farms to solve them.
Honeypots: Honeypots are traps designed to trick a bot into revealing itself1. Honeypots can be hidden elements on a web page, such as invisible links or forms, that humans would not interact with, but bots would. However, honeypots can also be detected by bots that use advanced techniques to avoid them.
Behavior analysis: Behavior analysis is the process of monitoring and evaluating the actions and patterns of users on a website or app. Behavior analysis can help detect bots that exhibit abnormal or suspicious behavior, such as high request frequency, low dwell time, or repetitive actions. However, behavior analysis can also be fooled by bots that use sophisticated algorithms to mimic human behavior.
Machine learning: Machine learning is the process of using data and algorithms to learn from patterns and make predictions. Machine learning can help detect bots that are constantly evolving and adapting to new situations. However, machine learning can also be challenged by bots that use adversarial techniques to generate noise or confusion.
Threat intelligence: Threat intelligence is the process of collecting and analyzing information about existing or emerging threats. Threat intelligence can help detect bots that are part of known botnets or campaigns. However, threat intelligence can also be outdated or incomplete for new or unknown threats.
How do bots avoid detection?
Bots are constantly evolving and adapting to new situations and challenges. They use various techniques and methods to avoid detection and appear like human users. Some of the common ways that bots try to bypass bot detection measures are:
Using proxies or VPNs: Proxies and VPNs are services that allow users to hide or change their IP address and location. Bots can use proxies or VPNs to mask their identity and origin, and to rotate their IP address frequently. This can help them avoid IP-based blocking or fingerprinting.
Spoofing headers or user agents: Headers and user agents are information that browsers send to servers when making requests. They contain data such as the browser name, version, operating system, language, etc. Bots can spoof headers or user agents to mimic different browsers or devices, and to rotate them randomly. This can help them avoid header-based blocking or fingerprinting.
Solving verification challenges: Verification challenges are problems that only humans can solve, such as CAPTCHAs or puzzles. They are used to filter out bots that cannot pass the test. Bots can use artificial intelligence, optical character recognition, or human farms to solve verification challenges. This can help them bypass challenge-based blocking.
Avoiding honeypots: Honeypots are traps designed to trick bots into revealing themselves. They are hidden elements on a web page, such as invisible links or forms, that humans would not interact with, but bots would. Bots can use advanced techniques to detect and avoid honeypots. This can help them bypass honeypot-based blocking.
Mimicking human behavior: Human behavior is the process of monitoring and evaluating the actions and patterns of users on a website or app. It is used to detect bots that exhibit abnormal or suspicious behavior, such as high request frequency, low dwell time, or repetitive actions. Bots can use sophisticated algorithms to mimic human behavior, such as randomizing their timing, scrolling, clicking, typing, etc. This can help them bypass behavior-based blocking.
Generating noise or confusion: Noise or confusion is the process of creating or manipulating data or information to mislead or deceive bot detectors. It is used to challenge machine learning models that use data and algorithms to learn from patterns and make predictions. Bots can use adversarial techniques to generate noise or confusion, such as adding irrelevant or false data, modifying existing data, or creating fake feedback loops. This can help them bypass machine learning-based blocking.
In this article, you have learned how to recognize a bot. You have learned that bots can perform various tasks, such as searching, interacting, creating, or harming. You have also learned that bots can be detected using different measures, such as fingerprinting, verification challenges, honeypots, behavior analysis, machine learning, and threat intelligence.
However, you have also learned that bots can bypass these measures using various techniques, such as proxies, spoofing, solving, avoiding, mimicking, or generating. Therefore, you have learned that bot detection is a complex and dynamic task that requires a comprehensive and adaptive solution.
