I was using wfuzz to scan for virtual hosts on Ariekei from HackTheBox, and one of the subdomains that I knew existed wasn't showing up. I'll do some quick troubleshooting, and learn a valuable lesson about how wfuzz (and other tools) measure size. I'll run a short wordlist through Burp Proxy to look at what's going on, and come to the conclusion that wfuzz (and other tools) doesn't look at HTTP headers when calculating size.
