This is a three-file standalone browser DoS repository: BrowserNuke.html contains the active HTML/JavaScript payload, README.md documents its claimed browser-crashing/resource-exhaustion behavior, and LICENSE is an MIT license. It is not associated with a recognized exploit framework and does not exploit a named CVE or software memory-corruption flaw. Instead, it is an operational, hardcoded client-side resource-exhaustion payload triggered immediately when the HTML is loaded. The main run() function stages pressure operations: heap and WebGL allocation begin immediately; audio, CSS rendering, DOM mutation, Blob allocation, and service-worker registration start shortly after; history flooding, iframe reload loops, animation-frame flooding, recurring DOM/render work, and a synchronous infinite allocation loop follow. The code contains no remote C2, IP address, hostname, or HTTP(S) target. Its only URL-like observable is the inline data:text/javascript, service-worker registration URL. The README's reference to index.html is inconsistent with the actual payload filename BrowserNuke.html.
