"Just ten more parts," he muttered, his coffee cold and forgotten.

In the dim glow of his dual monitors, Elias stared at the file he had spent three days hunting across the darker corners of the web: .

A text window popped open, but it wasn't WinRAR. It was a command prompt, lines of code scrolling faster than human eyes could track. In the center of the chaos, a single sentence remained static:

It was a ghost of a file, whispered about in IRC channels as the "Watch Dog" archive—supposedly a collection of decryptors for the most stubborn corporate firewalls. Elias moved his cursor over the icon. It looked harmless, just another compressed volume waiting for its siblings to complete the set.

He hit 'Extract' on the first part, watching the progress bar crawl. But as the bar hit 99%, the screen didn't flicker with a completion message. Instead, the pixels began to bleed. The vibrant blue of his wallpaper drained into a sickly, digitized grey.

"Part one is curiosity," the voice rasped. "Part two is the floorboards creaking."

Elias lunged for the power cable, but before his fingers could reach it, the speakers crackled with a voice that sounded like a thousand voices speaking at once.

Elias realized then that "WD" didn't stand for Watch Dog. He looked at his webcam—the tiny LED was glowing a steady, menacing crimson. On his desk, his phone buzzed with a notification from his smart-lock app: Front Door Unlocked. He hadn't downloaded a tool. He had invited a guest.
