Capture the Flag Challenge Review and Winners' Awards
summary
A browser-based Capture The Flag built as a staged “isolation” escape game uses terminal-like commands (help, tutorial, systemon) and keeps most state client-side with session IDs linked to a Yandex form. The organizers describe task types and solutions including crossword and coordinate-precision puzzles, image pixel and metadata extraction, audio-frame inspection, layered archive and gxl→PNG conversion, automated DOM clicking, XSLT/XML fixes, and debugging a browser extension via its service worker to reveal final flags; 36 participants found all mandatory flags and 9 completed every flag in this run.
