1

The Challenge

In early 2026, a top-tier international law firm in Gurugram noticed confidential strategy details regarding a major arbitration case leaking to opposing counsel.

An internal IT audit found no digital breach, leading investigators to focus on physical eavesdropping within the war room or senior partner cabin.

2

The Problem

Modern glass-heavy offices in Gurugram create unique vulnerabilities for counter-surveillance work, including laser microphone risk and open-plan acoustic leakage.

  • Audio recorder detection: digital recorders smaller than a coin that can capture hundreds of hours.
  • Laser microphone vulnerability: glass partitions exposed to adjacent buildings.
  • Threats for corporate reputation: malpractice exposure and privilege failure.
3

The Action

Indiebim initiated a midnight deep sweep under Wahid Shaikh’s direct supervision, combining technical sweeps with physical security audits.

  • Near-field RF spectrum analysis for store-and-forward bugs.
  • Acoustic leakage testing through HVAC ducts and glass windows.
  • NLJD scans across furniture, chairs, and desks for hidden semiconductor junctions.
4

The Findings

The team discovered a high-gain audio transmitter integrated into a PIR motion sensor in the main conference room, directly above the partner’s seat.

The device used the building’s Wi-Fi network through a masked SSID to stream encrypted audio in real time.

5

The Solution

  • Installed speech protectors that emit non-filtered ultrasonic noise to disrupt hidden microphones.
  • Applied anti-laser window film to prevent long-range laser microphone attacks.
  • Commissioned background checks for third-party vendors and facility-management staff.
6

Outcome

The law firm restored client confidence and was able to issue a security integrity certificate supported by military-grade TSCM countermeasures.

Technical Appendix

  • REI ANDRE for near-field broadband detection of nearby transmitters.
  • Wolfhound-PRO to track the cellular signature of the hidden GSM bug.
  • Laser Mic Defeat System to test and harden the glass facade.
