Internet bots, short for robots, are software programs that automate repetitive tasks and imitate human user behavior. While some bots serve useful functions like customer service or search engine indexing, others pose risks as malware bots.
Understanding the different types of bots and their potential dangers is crucial for individuals and organizations. In this article, we will explore the definition of bots, the risks associated with malicious bots, strategies to prevent and mitigate their impact and more.
What Is A Bot
A bot, or robot, is a software program designed to perform automated, repetitive tasks. These tasks can range from customer service interactions to indexing search engines. Bots are capable of operating at a much faster rate than humans, making them efficient tools for various purposes. However, they can also be used as malware to gain unauthorized control over a computer.
Computer Bots And Internet Bots
Computer bots and internet bots are digital tools that can be used for both good and bad purposes. Good bots perform useful tasks, such as automating customer service or assisting with search engine optimization. On the other hand, bad bots, also known as malware bots, pose risks by engaging in hacking, spamming, spying, and compromising websites. It is estimated that nearly half of all internet traffic today is generated by computer bots.
Malware Bots And The Dangers Of Internet Bots
Malware bots are programmed or hacked to carry out harmful activities, including breaking into user accounts, sending spam, or conducting other malicious acts. These bots can be distributed in botnets, which are networks of compromised devices running one or more bots without the owners’ knowledge. Botnets make it difficult to identify and block the source of malicious bot traffic, as they use multiple IP addresses.
Infection methods
Malware bots often infect computers through downloads, typically disguised as social media or email messages prompting users to click on a link. These links may contain viruses or other malware, infecting the computer and potentially making it part of a botnet. Additionally, bots can appear as warnings, tricking users into clicking on links that lead to virus infections.
Risks to consumers
Malicious bots pose risks to consumers, including data and identity theft, keylogging sensitive information like passwords and bank details, and phishing attempts. These bots can easily go unnoticed as they are often disguised as regular system files or processes, making detection challenging.
Examples Of Malicious Bots
Understanding the different types of malicious bots helps in recognizing potential threats and taking appropriate preventive measures. Here are some common examples:
Spambots: Spambots harvest email addresses or post promotional content in forums and comment sections to drive traffic to specific websites.
Malicious chatterbots: Chatterbots pretend to be humans on dating service websites and apps, aiming to obtain personal information, including credit card numbers, from unsuspecting victims.
File-sharing bots: These bots respond to user queries by claiming to have desired files available for download, leading users to unknowingly infect their computers.
Credential stuffing: Bots use known usernames and passwords, often sourced from data breaches, to gain unauthorized access to user accounts.
DoS or DDoS bots: Excessive bot traffic overwhelms server resources, causing denial of service (DoS) or distributed denial of service (DDoS) attacks.
Denial of Inventory Attacks: Malicious bots add items to online shopping carts without completing the transaction, leading legitimate users to receive false out-of-stock messages.
Vulnerability scanners: These bots scan websites for vulnerabilities and report them to their creators, who may sell the information or use it for hacking purposes.
Click fraud bots: These bots engage in ad fraud by fraudulently clicking on paid ads, costing advertisers significant amounts of money.
Traffic monitoring bots: Bots used for overloading mail servers or conducting large-scale data theft.

Why Do Cybercriminals Use Bots?
Stealing financial and personal information
One of the primary motivations for cybercriminals is to obtain financial and personal information from unsuspecting individuals. Bots can be utilized to send phishing scams or collect sensitive data from infected machines. This information is then used to commit identity theft, fraudulent financial transactions, or other illicit activities.
Attacking legitimate web services
Cybercriminals may deploy botnets, networks of compromised computers, to launch devastating attacks on legitimate web services. These attacks can take the form of DoS (Denial of Service) or DDoS (Distributed Denial of Service), overwhelming targeted websites or networks with an enormous volume of traffic. The result is a severe slowdown or complete shutdown of the targeted service, causing significant disruption and financial losses.
Extorting money from victims
Extortion is another tactic employed by cybercriminals using botnets. They may threaten to take down a company’s website or network unless a ransom is paid. The revenue from such attacks can come from the targeted company itself or from other groups interested in causing damage, such as hacktivists or foreign military and intelligence organizations.
Renting out botnets
Cybercriminals often monetize their botnets by leasing them to other criminals. These rented botnets can be used for various malicious activities, including spam campaigns, phishing attacks, identity theft, and targeting legitimate websites and networks. This underground economy allows cybercriminals to profit from their botnets without directly engaging in criminal activities themselves.
