In the last few years, the term “bot” has become widey used. Everyone is talking about bots. We hear it used in politics, on social media, and when discussing website traffic.
Bad bots are an all-too-common and growing problem. But what specific damage are they doing on your website? And how does it impact your business?
Bad bots scrape data from sites without permission in order to reuse it (e.g., pricing, inventory levels) and gain a competitive edge. The truly nefarious ones undertake criminal activities, such as fraud and outright theft.
The Open Web Application Security Project (OWASP) provides a list of the different bad bot types in its Automated Threat Handbook.
Left unaddressed, bad bots cause very real business problems that could harm the success — or even the continuance — of your organization. Examining the problems doesn’t require deep knowledge of the technology behind attacks or the techniques used to prevent them. Instead it requires a solid understanding of your business.
Here are some quick bad bots facts:
In 2017, 42.2% of all internet traffic wasn’t human, and there were significant year-over-year increases in both bad bot (+9.5%) and good bot (+8.8%) traffic.
GlobalDots created the following industry standard system that classifies the sophistication level of the following four bad bot types:

Bots are tailored to target very specific elements of a website, but can affect more than just stolen content, spammed forms, or account logins. The Open Web Application Security Project (OWASP) published the Automated Threats Handbook for Web Applications, which profiles the Top 20 automated threats and categorizes each threat as one of four types:
Every website is targeted for different reasons, so there’s no one-size-fits-all solution to the bot problem. There are, hoverer, certain steps you can take to make sure you’re protected from bad bots.
On its surface, a visit from a human and a bot may appear nearly identical. Bots can appear as normal users, with an IP address, browser and header data, and other seemingly identifiable information. But dig a bit deeper by collecting and reviewing in-depth analytics and other request data and you’ll be able to find the holes in the bots’ disguises.
Now that you’ve separated human traffic from bot traffic, you can dig a bit deeper to see which bots are good and which are bad. Good bots include search engine crawlers (Google, Bingbot, Yahoo Slurp, Baidu, and more) and social media crawlers (Facebook, LinkedIn, Twitter, and Google+). Generally, you want to allow these good bots access to your site, since they help humans find and access your site. Bad bots include any bots that are engineered for malicious use. These bots attempt scraping, brute force attacks, competitive data mining causing brownouts, account hijacking, and more.
Knowing the difference between the bots visiting your site lets you take action on bad bots and allow access to good bots.
Here’s overview of the things you must do before you can start protecting yourself from malicious bots.
Understand your vulnerabilities
Data is collected through every interaction and transaction online. Every business with a web presence is collecting sensitive data that might be of value to bad actors.
Businesses must continually evaluate and evolve their security measures to stay ahead of hackers. It’s crucial to understand the nature of the threat and have a clear plan of action to patch and protect their vulnerabilities online.
Tell the difference between bot protection myths and facts
In order to make informed and actionable decisions about the security in your business, it’s important to have the right information.
For example, you may have heard that all bots are bad. That’s not the case — there are plenty of bots that serve perfectly legitimate, even helpful functions.
It’s also often assumed that all bot attacks involve hacking. In fact, many bot attacks are simply probing for vulnerabilities that a hacker can exploit later.
Detect, categorize and control
Detecting bot traffic is the first step. Once bot traffic has been identified, the next step is to categorize the type of traffic. If it’s known bot traffic – like that of search engine bots – it should be allowed to pass. But known malicious bots, or bots of unknown intent, shouldn’t be allowed to pass.
Finally, the malicious bot traffic must be controlled. The type of bot mitigation required will depend on the type of attack. For a denial of service attack, your security software should simply divert the traffic. If the bot is looking for vulnerabilities or trying to commit fraud like shopping cart stuffing, the software should both deny access and return a false “page not found” 404 to the bot, to stave off future attacks from the same source.
