Category:OWASP Favicon Database Project
Idea is to have software enumerated via favicon.ico. How to do that? Take hash (in our case MD5) of favicon.ico and compare it against the known database. This project is about the favicon database itself and process in how to get the database.
Vlatko Kosturjak initially wrote .nse script for nmap to perform enumeration of software via favicon.ico. He has noticed that there is very small database of existing MD5 fingerprints of favicon.ico and also most of the current md5 fingerprinting implementations have only web server enumeration, he have added also some popular CMS, wikis, etc. I added some of them manually, but it's boring process. Fyodor suggested that we should do internet wide scan (nmap -iR 0) and gather the statistics and MD5 fingerprints of most usual favicons.ico and document them.
So, project has started the adventure of getting the statistics of MD5 fingerprints of most usual favicons.ico. We have faced problems how to enumerate http(s) hosts on Internet. Currently, we have recognized two types of http servers which we want to cover. First type is http servers on network devices and appliances and the second type is normal web servers with virtual hosts support.
You can read process, problem and solution on OWASP_favicon_database_crawl.
File:Favicon-md5-20090925.zip - Favicon MD5 database of most popular favicons found on the internet.
I have limited gathering scripts to fetch only favicon.ico from server root (i.e. /favicon.ico). So scripts will not parse HTML directives in order to find location of favicon. Reason is: simplicity.
Original scripts and files can be found at .
