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.
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.
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.
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.
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.
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.
