Definition: Search engine poisoning

Search engine poisoning (SEP) is a type of cyber attack in which malicious individuals or groups manipulate search engine results to spread malware or direct users to malicious websites. This is achieved by injecting fake or misleading information into the search index of a search engine, making it appear that malicious websites are relevant and trustworthy to the search query. The end goal of SEP is typically to spread malware, steal sensitive information, or generate advertising revenue through the creation of fake websites. To prevent SEP, it is important for users to be cautious when clicking on search results, and to keep their security software up-to-date.
