What is content scraping?

Content scraping (also known as web scraping) is the process of extracting content or data from third-party websites or applications, often without authorization. This data can be used in various ways—sometimes to copy content directly, but also to analyze or aggregate information for competitive advantage, or to sell insights or sensitive data for profit. While some organizations use scraping legitimately, it still represents a significant cyber threat when done without permission, posing risks around intellectual property, data privacy, and competitive misuse.

In targeted content-scraping attacks, bad actors initiate the process by deploying web crawlers to map and index the structure of a target website. These crawlers systematically analyze the site to identify key pages, links, and patterns, collecting information on the URLs and content areas of interest.

After this mapping stage, attackers develop a detailed script or set of instructions specifying the exact URLs or data points to target. This script is then fed to automated bots, which can attempt to bypass security measures by posing as legitimate users, sometimes even creating accounts or logging in to access gated or paid content. Once they gain the necessary access, these bots extract and capture the desired data, which can range from proprietary information to pricing data, product listings, or any unique content.

Finally, the extracted data is often repurposed or reposted on another site or platform, potentially to mislead users, create competitive advantages, or directly monetize the unauthorized content.

Online businesses scrape search engines and websites for legitimate purposes, such as price comparisons, or news and weather aggregation. Bad actors also scrape for pricing data to undercut competitors, and for marketing content that they repost to lure users from competitors, and for restricted content to resell on secondary markets.

Generative AI, especially large language models (LLMs), also frequently use content scraping to gather data for training and responding to user queries. This practice often bypasses consent and can lead to copyright violations or misinformation. For example, AI tools may summarize scraped content out of context, causing inaccuracies. Additionally, aggressive scraping by AI agents can strain site performance and inflate invalid traffic rates.

Content scraping causes losses in competitive advantage, user trust, and content integrity, as well as company revenue repercussions. Malicious actors target successful businesses to devalue and delegitimize their content to gain an advantage. Search engine optimization (SEO) rankings decline due to duplicate content, bot traffic wastes infrastructure, websites suffer from performance issues and become sluggish, and perpetrators can also disclose restricted content to the public.

Content scraping, though largely unregulated, can be effectively addressed through advanced bot detection tools that identify and prevent scraping tactics. Content-scraping bots often use strategies such as rotating user agents, using distributed IP addresses, and maintaining low-speed traffic to circumvent detection. These techniques enable scraper bots to blend in with regular website traffic, evading basic detection mechanisms based on IP rate limits or standard browser fingerprinting.

Sophisticated scraping bots are engineered to bypass traditional security measures, including web application firewalls (WAFs), basic bot detection systems, and even CAPTCHA challenges. By simulating human-like actions—such as mouse movements, clicks, and typing—scraping bots effectively evade detection while extracting valuable data from targeted sites. Bot detection tools tailored to prevent content scraping employ advanced behavioral analysis, machine learning, and threat intelligence to identify scraping-specific behaviors. For instance, they can detect irregular browsing patterns, inconsistencies in user-agent rotation, or unexpected requests to known content-heavy URLs.

As part of HUMAN’s Application Protection package, HUMAN Scraping Defense prevents content scraping attacks and manages bots from the moment they first visit a website. Using advanced machine learning, behavioral analysis, and intelligent fingerprinting, HUMAN Scraping Defense accurately detects human versus bot activity and enables businesses to customize their responses, either blocking, allowing or displaying alternate content to scraping bots.
