url fragments

The tag 'url fragments' on WindowsForum.com covers the security implications of the portion of a URL that appears after the '#' symbol, known as the fragment identifier. Recent discussions highlight a prompt-injection attack called HashJack, which weaponizes URL fragments to deliver malicious instructions to AI-powered browser assistants. This technique can trick assistants into displaying fake login prompts, exfiltrating data, or showing deceptive UI, all while bypassing traditional server-side defenses. The tag focuses on how these fragments, often overlooked in security analysis, can be exploited in modern browser environments, particularly with the rise of AI assistants that process page content client-side.
