The Challenge

In early 2026, a major coal mining corporation in Ranchi discovered that its reserve price calculations for a major government auction had leaked.

With a tiny pricing gap capable of changing the outcome of a thousand-crore tender, the client suspected the tender room itself had been physically compromised.

2

The Problem

Mining headquarters face constant traffic from engineers, contractors, and technical visitors, making ruggedized equipment and ceremonial objects plausible hiding places for bugs.

  • Audio recorder detection in rooms filled with technical blueprints and surveying equipment.
  • Threats for corporate assets involving geological data and bidding strategy.
  • Suspicion that bugs were hidden inside mining-themed office equipment and decor.
3

The Action

Wahid Shaikh led a Deep Vein sweep using a zero-emission scan protocol focused on business-hour burst transmissions, concealed electronics, and parasitic power draw.

  • RF mapping with a spectrum analyzer to isolate signals active only during work hours.
  • NLJD inspection of surveying tools and mine models.
  • Power-line analysis for devices drawing hidden current from the main server rack.
4

The Findings

The team uncovered a miniature GSM audio bug and a power-bank integrated recorder hidden inside a decorative gold-plated first coal extraction trophy in the chairman’s strategy room.

The trophy base had been hollowed out to conceal a bug transmitting audio through a 4G SIM card.

The Solution

  • Mandated TSCM scanning for ceremonial gifts before executive-floor placement.
  • Installed ultrasonic white-noise generators in the tender room.
  • Audited facility maintenance staff and access history.
