“Professor, I’m sorry. I can’t open Mira’s part of the project. I have version 7.2.2. I tried to download 7.3.1 unofficially, but it was malware.”
He clicked.
The domain was a messy string of characters—something like dl.tech-archive.xyz . No SSL certificate. A “Download” button surrounded by blinking ads for driver updaters and fake antivirus software.
The flickering glow of the monitor was the only light in the cramped dorm room. Rain lashed against the window, a steady rhythm that matched the anxiety thrumming through Leo’s chest.
