A heavy silence filled the line. "Can you patch it? Re-flash the original firmware?"

It was a dead man's switch. Someone had planned for the drone to be captured, or for its operator to be killed. The moment the link was broken, the betrayal would begin.

"We traced it. It wasn't a traitor. It was a ghost. An old piece of code from a black-budget program that was supposedly terminated ten years ago. Someone resurrected it, compiled it into that firmware, and seeded it into the supply chain."

"That's the terrifying part. Look at the signature." She highlighted a block of code. "This uses the same encryption primitives as our own field communicators. It's not enemy action, Marcus. Someone inside the supply chain flashed this firmware. The drone is a wolf in sheep's clothing. At any moment, whoever holds the second key can seize control, turn it against our own troops."

The lab was a tomb of humming servers, but to Elara, it was home. She was the ghost in the machine, the one the Company called when a system was too broken for anyone else to fix. Her current assignment: the Aquila C2.

"I can't disable it without the heartbeat stopping and triggering the self-destruct. But I can replace it." She took a deep breath. "I'm going to inject new microcode into the power management unit. It'll create a fake, local heartbeat—a ghost signal that satisfies the parasite's condition. Then, while the parasite is pacified, I'll overwrite the entire firmware block with version 4.2.1-d."
