What are bots? – Definition and Explanation – Kaspersky
Bots – meaning & definition
A ‘bot’ – short for robot – is a software program that performs automated, repetitive, pre-defined tasks. Bots typically imitate or replace human user behavior. Because they are automated, they operate much faster than human users. They carry out useful functions, such as customer service or indexing search engines, but they can also come in the form of malware – used to gain total control over a computer.
Internet bots can also be referred to as spiders, crawlers, or web bots.
What is a computer bot and what is an internet bot?
Computer bots and internet bots are essentially digital tools and, like any tool, can be used for both good and bad.
Good bots carry out useful tasks, however, bad bots – also known as malware bots – carry risk and can be used for hacking, spamming, spying, interrupting, and compromising websites of all sizes. It is estimated that up to half of all internet traffic today is made up of computer bots carrying out certain tasks, such as automating customer service, simulating human communication on social networks, helping companies search online for content and assisting with search engine optimization.
Organizations or individuals use bots to replace repetitive tasks that a human would otherwise have to perform. Tasks run by bots are typically simple and performed at a much faster rate when compared to human activity. Though not all tasks performed by bots are benign – sometimes bots are used for criminal activities such as data theft, scams, or DDoS attacks.
Malware bots and the dangers of internet bots
Malware bots and internet bots can be programmed/hacked to break into user accounts, scan the internet for contact information, to send spam, or perform other harmful acts.
To carry out these attacks and disguise the source of the attack traffic, attackers may distribute bad bots in a botnet – i. e., a bot network. A botnet is a number of internet-connected devices, each running one or more bots, often without the device owners’ knowledge. Because each device has its own IP address, botnet traffic comes from numerous IP addresses, making it harder to identify and block the source of the malicious bot traffic. Botnets can often grow themselves by using devices to send out spam emails, which can infect more machines.
One of the most common ways in which bots infect your computer is via downloads. Malware is delivered in download format via social media or email messages that advise clicking a link. The link is often in picture or video form, with either containing viruses and other malware. If your computer is infected with malware, it may be part of a botnet.
A bot can also appear as a warning saying that your computer will get a virus if you do not click on the associated link. Clicking the link subsequently infects your computer with a virus.
While malware bots create problems and issues for organizations, the dangers for consumers include their potential for carrying out data and identity theft, keylogging sensitive information such as passwords, bank details and addresses, and phishing.
Malicious bots can easily go unnoticed. They are easily hidden within a computer and often have file names and processes similar if not identical to regular system files or processes.
Examples of malicious bots include:
Spambots may harvest email addresses from contact or guestbook pages. Alternatively, they may post promotional content in forums or comment sections to drive traffic to specific websites.
Dating service websites and apps are havens for malicious chatterbots. These chatterbots pretend to be a person, emulating human interaction, and often fool people who don’t realize they are chatting to harmful programs whose goal is to obtain personal information, including credit card numbers, from unsuspecting victims.
These bots take the users’ query term (such as a popular movie or artist’s album) and respond to the query stating that they have the file available for download, providing a link. The user clicks on the link, downloads, and opens it, and unknowingly infects their computer.
This refers to bots “stuffing” known usernames and passwords (usually sourced from data breaches) into online log-in pages to gain unauthorized access to user accounts.
DoS or DDoS bots
This is where excessive bot traffic is intentionally used to overwhelm a server’s resources and prevent a service from operating.
Denial of inventory attacks
These attacks target online shops to list their products as ‘not available’. In this type of attack, malicious bots access the shopping cart, select items from the online store, and add them to the shopping cart, never completing the transaction. As a result, when a legitimate user wants to buy the product, they receive an out-of-stock message, even if the item is in stock.
Bots which scan millions of sites for vulnerabilities and report them back to their creator are known as vulnerability scanners. Unlike genuine bots that would inform the website owner, these malicious bots are specifically made to report back to one person who then sells the information or uses it themselves to hack websites.
Click fraud bots
These bots produce a huge amount of malicious bot traffic specifically targeting paid ads to engage in ad fraud. Responsible for fraudulently clicking paid ads, this non-human traffic costs advertisers billions every year and is often disguised as legitimate traffic. Without good bot detection software, this bot activity can cost advertisers a large proportion of their ad budget.
Bots which are used for overloading mail servers or carrying out large-scale data theft.
Why do cybercriminals use bots?
1. To steal financial and personal information
Hackers may use botnets to send phishing or other scams to trick consumers into giving away their money. They may also collect information from the bot-infected machines and use it to steal identities and incur loans or purchase charges in the user’s name.
2. To attack legitimate web services
Criminals may use botnets to create DoS and DDoS attacks that flood a legitimate service or network with a crushing volume of traffic. The volume may severely slow down the company’s service or network’s ability to respond, or it may entirely overwhelm the company’s service or network and shut them down.
3. To extort money from victims
Revenue from DoS attacks comes through extortion (i. e., pay or have your site taken down) or through payments by groups interested in inflicting damage to a company or network. These groups include “hacktivists” — hackers with political agendas as well as foreign military and intelligence organizations.
4. To make money from zombie and botnet systems
Cybercriminals may also lease their botnets to other criminals who want to send spam, scams, phishing, steal identities, and attack legitimate websites and networks.
Types of bots
Aside from malware bots, what do bots do? There are many different types:
Bots that simulate human conversation by responding to certain phrases with programmed responses.
Bots which operate on social media platforms, and are used to automatically generate messages, advocate ideas, act as a follower of users, and as fake accounts to gain followers themselves. As social networks become more sophisticated, it is becoming harder for social bots to create fake accounts. It is difficult to identify social bots because they can exhibit similar behavior to real users.
Bots that shop around online to find the best price for products a user is looking for. Some bots can observe a user’s patterns in navigating a website and then customize that site for the user.
Spider bots or web crawlers
Web scraping crawlers
Bots that read data from websites with the objective of saving them offline and enabling their reuse. This may take the form of scraping the entire content of web pages or scraping web content to obtain specific data points, such as names and prices of products on e-commerce websites.
Bots that collect knowledge for users by automatically visiting websites to retrieve information which fulfils certain criteria.
Bots used to monitor the health of a website or system. is an example of an independent site that provides real-time status information, including outages, of websites and other kinds of services.
Bots used to complete transactions on behalf of humans. For example, transactional bots allow customers to make a transaction within the context of a conversation.
Bots that are used to automatically download software or mobile apps. They can be used to manipulate download statistics – for example, to gain more downloads on popular app stores and help new apps appear at the top of the charts.
They can also be used to attack download sites, creating fake downloads as part of a Denial of Service (DoS) attack.
Bots which automatically purchase tickets to popular events, with the aim of reselling those tickets for a profit. This activity is illegal in many countries, and even when not against the law, it can be a nuisance to event organizers, legitimate ticket sellers, and consumers. Ticketing bots are often sophisticated, emulating the same behaviors as human ticket buyers.
How do bots work?
Typically, bots operate over a network. Bots that can communicate with one another will use internet-based services to do so – such as instant messaging, interfaces like Twitterbots or through Internet Relay Chat (IRC).
Bots are made from sets of algorithms which help them to carry out their tasks. The different types of bots are designed differently to accomplish a wide variety of tasks.
Take chatbots as one example – they have different methods of operation:
A rule-based chatbot interacts with people by giving pre-defined prompts for the individual to select.
An intellectually independent chatbot will use machine learning to learn from human inputs as well as looking out for known keywords.
AI chatbots are a combination of rule-based and intellectually independent chatbots. Additionally, chatbots may also use pattern matching, natural language processing and natural language generation tools.
There are pros and cons to each – organizations which use bots will decide which approach is best based on their requirements.

How to tell if your computer is infected by bots
Ways in which you can tell if your computer is part of a botnet include:
Your computer keeps crashing without an identifiable reason.
Applications that previously worked seamlessly now work in fits and starts.
Programs which previously loaded quickly are now slow to start.
The computer takes a long time to shut down or does not shut down properly.
Your internet access slows to a crawl.
The browser features components you didn’t download.
Windows Task Manager shows programs with cryptic names or descriptions.
Settings have changed, and there is no way to reverse them.
Pop-up windows and advertisements appear even when you are not using a web browser.
The fan goes into overdrive when the device is idle.
Friends and family report receiving email messages from you, but you did not send them.
You cannot download operating system updates.
What to do if your computer is infected by bots
If your computer is already infected by bots, the most important consideration is protecting your data.
Here are some steps to take:
Step 1: Disconnect your computer from the network as soon as possible – this will stop the theft of sensitive information and prevent your computer from being used to attack other networks.
Step 2: Move all important or personal data to another computer or an external hard drive. Ensure these are malware-free before you do.
Step 3: Carry out a factory reset of your machine (bear in mind that as well as targeting the problem, it will also remove files and programs you have created, delete drivers, and return settings to their defaults)
Step 4: Clean your computer using various security tools or by asking a professional to work on the device
Remember, prevention is the best cure when it comes to bots and all other forms of malware. So, it’s important to have cybersecurity installed on all your devices.
How to protect your computer from bots
The difficulty for consumers is that many online customer touchpoints – including websites, mobile apps, and APIs – are being attacked by bots. It is possible to protect your computer from bots, but it requires vigilance and knowing what to look for.
Here are some steps to take to protect your systems from botnet infiltration:
Install anti-malware software
Use comprehensive anti-malware software to protect your device. For example, Kaspersky Total Security blocks viruses and malware in real-time and stops hackers from taking over your PC remotely. Make sure your anti-virus and anti-spyware programs are set to update automatically.
Ensure all your software is up to date
Never ignore system updates. Routinely check for browser and operating system updates and patches.
Use a strong password
A strong password is difficult to guess and includes a combination of uppercase and lowercase letters plus numbers and symbols. Avoid using the same password for multiple accounts. We recommend using a secure password manager tool.
Only click on links you trust
Only click internet links or open emails if you trust the source. Common user risks occur when downloading content from unknown sites or from friends who don’t have up-to-date protections and unwittingly pass infected files to other users.
Always use extreme caution when downloading information or files from someone whose computer is not protected. Avoid using flash drives, or thumb drives, in an infected computer.
Avoid untrustworthy websites and ads
A common way users are tricked into downloading malware bots is through intriguing ads or downloads they come across during web browsing. Be cautious about downloading free versions of software from websites you don’t recognize, and never click on pop-up ads that claim only they can fix your computer’s performance or virus issues. In many cases, interacting with these pages will trigger a malware installation on your computer.
Install a firewall
A firewall can help to block malicious attacks.
Use a bot manager
Organizations can stop malicious bots by using a bot manager. Bot managers can be included as part of a web app security platform.
A bot manager can be used to allow the use of some bots and block the use of others that might cause harm to a system. To do this, a bot manager will classify any incoming requests by humans and good bots and known malicious and unknown bots. Any suspect bot traffic is then directed away from a site by the bot manager.
Some basic bot management feature sets include IP rate limiting and CAPTCHAs. IP rate limiting will limit the number of same-address-requests, while CAPTCHAs often use a puzzle to differentiate bots from humans.
Remember, good bots are a crucial part of the internet’s infrastructure and perform many useful tasks. But bad bots are difficult to detect without an anti-virus program because they are designed to hide in plain sight. So, it is important to be aware of the risks posed by malicious bots, and practice good cybersecurity at all times.

What are Bots and How Do they Work? – WhatIs.com
A bot — short for “robot” and also called an internet bot — is a computer program that operates as an agent for a user or other program, or to simulate a human activity. Bots are normally used to automate certain tasks, meaning they can run without specific instructions from humans.
An organization or individual can use a bot to replace a repetitive task that a human would otherwise have to perform. Bots are also much faster at these tasks than humans.
How do bots work?
Normally, bots will operate over a network. Bots that can communicate with one another will use internet-based services to do so — such as instant messaging, interfaces like Twitterbots or through Internet Relay Chat (IRC). In general, more than half of internet traffic is bots that interact with web pages, talk with users, scan for content and perform other tasks.
Bots are made from sets of algorithms which aid them in their designated tasks. Tasks bots can normally handle include conversing with a human — which attempts to mimic human behaviors — or gathering content from other websites. There are plenty of different types of bots designed differently to accomplish a wide variety of tasks.
As an example, a chatbot will operate on one of multiple methods of operation. A rule-based chatbot will interact with people by giving pre-defined prompts for the individual to select. An intellectually independent chatbot will make use of machine learning to learn from human inputs as well as watching out for known keywords. AI chatbots are a combination of rule-based and intellectually independent chatbots. Chatbots may also use pattern matching, natural language processing (NLP) and natural language generation (NLG) tools.
Organizations or individuals that make use of bots can also use bot management software, which includes software tools that aid in managing bots and protecting against malicious bots. Bot managers can be included as part of a web app security platform. A bot manager can be used to allow the use of some bots and block the use of others that might cause harm to a system. To do this, a bot manager will classify any incoming requests by humans and good bots and known malicious and unknown bots. Any suspect bot traffic is then directed away from a site by the bot manager. Some basic bot management feature sets include IP rate limiting and CAPTCHAs. IP rate limiting will limit the number of same-address-requests, while CAPTCHAs are used as a sort of puzzle to differentiate bots from humans.
Types of bots
There are numerous types of bots, all with unique goals and tasks. Some common bots include:
A chatbot — which is a program that can simulate talk with a human being. One of the first and most famous chatbots (prior to the web) was Eliza, a program that pretended to be a psychotherapist and answered questions with other questions.
Social bots — which are bots that operate on social media platforms.
A shopbot — which is a program that shops around the web on your behalf and locates the best price for a product you’re looking for. There are also bots such as OpenSesame that observe a user’s patterns in navigating a web site and customize the site for that user.
A knowbot — which is a program that collects knowledge for a user by automatically visiting Internet sites to retrieve information that meets certain specified criteria.
Spiders or crawlers (also known as a web crawler) — which are used to access web sites and gather their content for the indexes in search engines.
Web scraping crawlers — which are similar to crawlers but are used for data harvesting and extracting relevant content.
Monitoring bots — which can be used to monitor the health of a website or system.
Transactional bots — which can be used to complete transactions on behalf of a human.
Bots may also be classified as good bots and bad bots, or in other words, bots that will not harm the system and bots that pose threats and can harm the system.
Examples and uses of bots
Bots can be used in customer service fields as well as in areas like business, scheduling, search functionality and entertainment. Using a bot in each area brings different benefits. For example, in customer service, bots are available 24/7 and increase the availability of customer service employees, allowing them to focus on more complicated issues.
Red and Andrette were names of two early programs that could be customized to answer questions from users seeking service for a product. Such a program is sometimes called a virtual representative or a virtual agent.
Other services that use bots include:
Instant messenger apps such as Facebook Messenger, WhatsApp and Slack;
News apps such as the Wall Street Journal, to show news headlines;
Spotify, which allows users to search for and share tracks via Facebook Messenger;
Lyft, in which a user can request a ride from instant messenger apps; and
Meeting scheduling services, such as
Malicious bots are bots used to automate actions considered to be cybercrimes. Common types of malicious bots include:
DoS or DDoS bots, which use an overwhelming number of bots to overload a server’s resources and halting the service from operating.
Spambots, which post promotional content to drive traffic to a specific website.
Hackers, which are bots made to distribute malware and attack websites.
Other malicious bots include web crawlers, credential stuffing, email address harvesting and brute force password cracking. Organizations can stop malicious bots by using a bot manager.
Advantages and disadvantages
There are plenty of advantages that come with using bots as well as disadvantages, such as risks that other bots could propose. Some potential advantages of bots include:
Faster than humans at repetitive tasks;
Time saved for customers and clients;
Organizations can reach large numbers of people via messenger apps;
Bots are customizable; and
Improved user experience.
Some disadvantages include:
Bots cannot be set to perform some exact tasks and they risk misunderstanding users.
Humans are still necessary to manage the bots as well as to step in if one misinterprets another human.
Bots can be made malicious by users.
Bots can be used for spam.

Good Bots vs. Bad Bots, And Their Impact On Your Website | Radware Bot Manager
ShieldSquare is now Radware Bot Manager
Bots are programs created to automate various and often repetitive tasks ─ useful as well as harmful ─ hence they are generally described as either good bots or bad bots. Several studies have shown that over 50% of all internet traffic is comprised of bots. However, the malicious ones get the most attention as they must be detected and blocked before they cause any harm.
What Are Good Bots?
Good bots are beneficial to businesses as well as individuals. When you search for a website or phrases related to a website’s products or services, you get relevant results listed in the search results page. This is made possible with the help of search engine spiders bots, also known as crawler bots (such as GoogleBot, Bingbot, and Baidu Spider, to name a few). Good bots are generally deployed by reputable companies, and for the most part they respect rules created by webmasters to regulate their crawling activity and indexing rate, which can be defined in a website’s file for crawlers to see. Certain crawlers can also be prevented from indexing websites if they are not useful or needed by the business. For example, the Baidu crawler can be blocked if a business does not operate in China and/ or does not cater to the Chinese market.
Apart from search engine crawlers, good bots also include partner bots (e. g. Slackbot), social network bots (e. Facebook Bot), website monitoring bots (such as Pingdom), backlink checker bots (e. SEMRushBot), aggregator bots (like Feedly), and more. Even good bots such as crawlers can cause problems at certain times, such as when their traffic increases and starts to reach the limits of server capacity, or when their volumes result in skewed analytics.
Our research report ‘Inside Good Bots’ details the most common types of good bots, the functions they carry out, and recommendations on how to optimally manage them according to your specific objectives.
What Are Bad Bots?
Bad bots are programmed to perform a variety of malicious jobs. They work in an evasive manner and are mostly used by fraudsters, cybercriminals, and nefarious parties engaged in various illegal activities. They can be sent by third-party scrapers or your competitors to steal content from your website, such as product reviews, breaking news, product pricing information and catalogs, user generated content on community forms, and so on. When they make thousands of page visits within a very short span of time, they strain Web servers and choke the available bandwidth, slowing down the site for genuine users.
Bots can scrape your content and publish it elsewhere. This can affect your website’s search engine rankings. There have been instances of stolen content outranking the original content on Google search pages. This directly impacts the bottom-line of the websites that have invested large sums to create original content. They can spam community forums with intrusive ads or messages. They can create millions of fake leads on real-estate and classifieds portals, carry out cart abandonment on e-commerce portals, distort marketing analytics, take over accounts to steal stored value in the form of store credits, loyalty points, prepaid wallets and so on.
Bad bots have evolved to become highly sophisticated and human-like in their behavior and can leverage vast computing resources at cloud data centers to carry out their malicious activities, largely evading conventional or in-house bot detection methodologies. They can even influence political elections.
How to Stop Bad Bots
First, we recommend using our free Bad-bot Vulnerability Scanner to find out the extent of the bot traffic on your website, apps, and APIs. You could also try our free Bad Bot Analyser that shows you the types of bot traffic your site receives. If you’re thinking of developing an in-house bot manager, you should know that they have several downsides and are ineffective against sophisticated bots that can mimic human behavior. In addition, the rapid evolution of bots and their attack techniques makes it virtually impossible to reliably detect advanced bots in real-time before they do their damage. A dedicated bot management solution provides enterprises with specialized bot identification and detection capabilities that are regularly updated with the latest bot signatures. Moreover, solutions such as Radware Bot Manager leverage machine learning and advanced heuristics to detect sophisticated non-human traffic even in the absence of a recognized bot signature, ensuring protection from future automated threats.
In their ‘New Wave™: Bot Management, Q3, 2018’ Report, Forrester Research recommends that “Bot management tools must determine the intent of automated traffic in real time to distinguish between good bots and bad bots. ” Before choosing a bot management solution, learn about the key evaluation criteria in selecting a solution that best meets your needs. Also, our Resources section contains useful research reports that detail the ways in which bad bots attack websites in various industries, and how they can be managed.
