Ghost in the Grid

The anomaly appeared at 3:47 AM inside Delhi's city management feed — a single misaligned packet, nested inside INDRA's traffic module, broadcasting on a frequency no official system used. Rohan almost missed it. He was on his third chai of the night, watching a pirated cricket match. He paused the match. He read the packet three times. INDRA — the Integrated Network for Delhi's Resource Administration — had been running the capital for eighteen years: power, water, traffic, emergency response, air quality, subsidy disbursements. Its code was theoretically open-source. Rohan had been auditing it as a hobby for two years without finding anything interesting.

This was not uninteresting. It was a hidden subroutine designed to look like noise, communicating with something outside the official network. He saved the packet. He looked at the holo-map of Delhi glowing above his desk — twenty-two million lights, every one of them running on INDRA's invisible rails. Then he opened his terminal and started to dig.
