Dead Domain Discovery

Scans the page for external iFrames, Scripts, and Styles, logs them to the console, and checks if their domains are resolvable.

This Chromium extensions aims to identify abandoned domains that are referenced by a website for instance within an iFrame, as script or as CSS source. If an abandoned domain is used within these sinks, which can be registered by malicious actors, this could for instance lead to Cross-Site Scripting or website defacement vulnerabilities. Features: • Gather relevant sources, keep track of previously encountered domains. • Lookup domains and send a Chrome Notification in case a domain lookup fails. • History of findings. • Config: Exclude domains from analysis, set cache lifetime.
