He could remote-control a struggling student’s mouse to show them a syntax error, distribute files in a heartbeat, and even "show" his screen to everyone at once without turning on the dusty projector.

But the digital underground always extracts a price. On Friday, the "kuyhaa" version showed its true colors. A strange pop-up in a language Henderson didn't recognize appeared on every screen. The mouse cursors began to move on their own, dancing in a synchronized pattern. The "full" version had brought along some uninvited guests—malware that turned the lab into a crypto-mining farm.

The cat videos vanished, replaced by Henderson’s own lecture slides, pushed directly to their monitors with a single click.
