Introducing CoWitness: Enhancing Web Application Testing…

This blog post introduces CoWitness, a lightweight Go-based HTTP and DNS server for web application testers that captures DNS lookups and HTTP requests (including URIs and User-Agent) to help differentiate true application callbacks from false positives caused by CDNs or intrusion protection. The article explains registering glue records for a controlled domain, configuring and compiling the CoWitness code, running it on ports 80/443/53, and monitoring http.log and dns.log to analyze incoming requests and identify potential application behavior.
