An embedded video is media placed directly inside a web page or article, instead of forcing the viewer to open a separate file or site. It is commonly used to show a process, demo, or walkthrough in context, and may be hosted locally or pulled from a third-party platform through an iframe or player widget.
In cybersecurity, embedded video matters because it can introduce external content, tracking code, or extra browser permissions that the page owner does not fully control. A malicious or compromised embed may help phish users, fingerprint visitors, or hide unsafe links behind a familiar player. Defenders review embedded media when checking content security policy, sandboxing, referral leakage, and third-party risk. In security training and incident writeups, an embedded video can also be useful for showing evidence, attack steps, or response procedures without relying only on text.
