Counter-Strike. A strange AppID to leave as bait. Mira had been hunting for months, scraping dead drop forums, following breadcrumbs left by a collective called the "Keymakers." They claimed to have found a way to abuse Steam’s deprecated content servers—to force them into serving not game manifests, but raw, unfiltered system access.
