Favicons are small graphic icons that appear in browser tabs or bookmarks. By viewing a website’s source code, you can locate the favicon link. Traditionally, favicons were .ico files, but now they can be various image formats. Favicons have specific sizes like 16×16, 32×32, and 64×64 pixels. Different devices may require different favicon sizes. Favicons are used for browser navigation, user experience, SEO, brand recognition, and more. In investigating fake websites or phishing campaigns, analyzing favicons can help identify rogue websites. Tools like Favicone, Favicon Grabber, and Favihash can assist in favicon research by generating hash values for comparison on platforms like Virus Total and Shodan.
