DOM scraping is a technique used to extract information from web pages by accessing and processing their Document Object Model (DOM). The DOM represents the structure and content of a webpage as a tree of objects, which can be programmatically navigated and manipulated. Cybersecurity concerns arise when attackers use DOM scraping to harvest sensitive data, such as user credentials or private content, often bypassing traditional security controls. This method can be employed for both legitimate purposes, like web automation and data aggregation, or for malicious intent, such as reconnaissance and data theft. Protecting against unauthorized DOM scraping involves implementing measures like rate limiting, CAPTCHAs, and obfuscating sensitive elements.
