ParamSpider is a Python-based tool that extracts URLs from web archives to support security research activities. The tool mines URLs from various web archive sources, focusing on discovering endpoints that may not be easily accessible through conventional crawling methods. It is designed to assist security researchers and bug hunters in identifying potential attack surfaces by uncovering URLs that contain parameters and endpoints from archived web content. The tool can be used as part of reconnaissance activities to gather URLs for further security testing, fuzzing, and vulnerability assessment. ParamSpider helps researchers expand their target scope by accessing historical web data that may contain valuable information about web application structure and parameters.
