What are Bad Bot Attacks? Exploring the Impact of Malicious Bots on Websites



As an IT professional, you know that website security is crucial for online businesses. However, while many organizations focus on defending against malware, phishing scams, and other forms of cybercrime, they may overlook the growing threat of bad bot attacks. In this article, we’ll explore what bad bot attacks are, their impact on websites, and how to prevent them.


What are Bad Bot Attacks?

Bad bot attacks are malicious actions carried out by automated programs, or bots, that mimic human behavior to gain unauthorized access to websites. Unlike good bots, which are used for legitimate purposes like web indexing or content scraping, bad bots are designed to perform nefarious activities such as account takeovers, web scraping, and DDoS attacks.

Bad bots come in different forms, including web scrapers, spambots, and credential stuffing bots. Web scrapers are used to extract data from websites, while spambots generate spam content in comments and contact forms. Credential stuffing bots use stolen login credentials to gain unauthorized access to accounts.

How Bad Bots Work

Bad bots work by exploiting website vulnerabilities to automate their malicious activities. They can be programmed to navigate through a website, fill out forms, and perform other actions to achieve their objectives. Bad bots can be difficult to detect as they often mimic human behavior and use rotating IP addresses and user agents.


Impact of Bad Bot Attacks

The impact of bad bot attacks can be severe for both website owners and users. Website performance can be affected by an influx of bot traffic, resulting in slow page load times or even downtime. Additionally, bad bots can steal sensitive data such as credit card numbers, login credentials, and personal information.

Some notable bad bot attacks include the 2016 Dyn DDoS attack, which targeted DNS provider Dyn, and the 2020 Credential Stuffing attack on food delivery service Deliveroo.

How to Detect Bad Bot Attacks

Detecting bad bot attacks requires a combination of manual and automated methods. Some tools used to identify bad bots include web server logs, network traffic analysis tools, and bot detection software. Best practices for monitoring website traffic include analyzing user behavior and implementing rate limiting to reduce the number of requests from suspicious IPs.


How to Prevent Bad Bot Attacks

Preventing bad bot attacks requires a proactive approach to website security. Strategies for preventing bad bots include implementing CAPTCHAs or honeypots to deter bots, using web application firewalls to filter out malicious traffic, and regularly updating website software to patch known vulnerabilities.


What to Do if Your Website is Attacked by Bad Bots

If your website is under attack by bad bots, the first step is to identify the source and type of bot. You can then take steps to block the bot using firewalls or blacklist the offending IP addresses. It’s also important to change any compromised credentials and review security measures to prevent future attacks.

Handling bad bot attacks can be a challenging and complex process, but there are several steps that organizations can take to protect themselves and their customers. Here are some tips on how to handle bad bot attacks:


Identify the source and type of bot: The first step in handling a bad bot attack is to identify the source and type of bot. This can be done by analyzing web server logs, network traffic, and other data sources.

Block the bot: Once you’ve identified the bot, you can take steps to block it. This can be done by using firewalls to block the bot’s IP address, blacklisting the IP address in your web application firewall, or using a bot detection service to block the bot.

Change compromised credentials: If the bad bot has gained access to user accounts, it’s important to change any compromised credentials immediately. This includes passwords, usernames, and other account information.


Review and improve security measures: After handling a bad bot attack, it’s essential to review your organization’s security measures and make improvements where necessary. This can include implementing two-factor authentication, using stronger passwords, and updating software to patch known vulnerabilities.


Monitor for future attacks: Finally, it’s important to monitor your website for future bad bot attacks. This can be done by implementing web application firewalls, analyzing website traffic, and staying up-to-date on the latest security threats.


Handling bad bot attacks can be a time-consuming and resource-intensive process, but by taking these steps, organizations can protect themselves and their customers from the harmful effects of bad bots. Additionally, it’s essential to work with a reputable web hosting provider that can offer the necessary technical support and security measures to prevent and mitigate bad bot attacks.



Bad bot attacks pose a significant threat to website security and require proactive measures to prevent and detect them. As we’ve seen, bad bots can cause significant damage to websites, resulting in slow page load times, downtime, and data breaches.

As an IT professional, it’s crucial to stay up-to-date on the latest security threats and implement best practices to protect your organization and its customers. This includes regularly monitoring website traffic, analyzing user behavior, and using web application firewalls to filter out malicious traffic.

Preventing bad bot attacks requires a combination of technical and non-technical measures. In addition to implementing security software, organizations must also educate employees and customers about the risks of bad bots and how to stay safe online. This includes reminding employees to use strong passwords and encouraging customers to enable two-factor authentication on their accounts.

While bad bot attacks are a growing threat, IT professionals can take steps to protect their organizations and customers from these malicious programs. By staying vigilant and implementing best practices, organizations can minimize the risk of bad bot attacks and keep their websites secure. Ultimately, investing in website security is an investment in the trust and loyalty of your customers, which can pay off in the long run.
