Banking Espionage and Financial Security in Chennai

A major private sector bank in Chennai found that highly sensitive information regarding NPA recovery strategies and upcoming interest rate revisions was being leaked to media and rival institutions.

Investigators suspected the boardroom of directors and chairman’s communications were being physically monitored.

The bank’s headquarters blended modern glass offices with older infrastructure, creating blind spots across phone systems, archives, and executive spaces.

• Audio transmitter detection in complex telephone exchange environments.
• Audio recorder detection hidden inside archival and boardroom spaces.
• Threats for corporate integrity including regulatory and reputation risk.

Wahid Shaikh led a 72-hour deep-dive TSCM audit with emphasis on voice infrastructure, RF anomalies, and executive-room hardware.

• Telephone line analysis using REI TALAN 3.0.
• RF spectrum analysis for sub-carrier signals hidden within legitimate broadcasts.
• NLJD scans across the executive table and leather-lined walls.

Indiebim discovered a digital wiretap in the main junction box serving the chairman’s office and a GSM audio bug hidden inside a standard-looking desktop calculator.

The wiretap stored calls locally, while the calculator bug enabled live room monitoring.

• Oversaw migration to end-to-end encrypted voice systems.
• Established a monthly TSCM schedule before board meetings.
• Audited cleaning and maintenance staff access to executive floors.

The bank completed its recovery strategy without further leaks and protected its reputation for confidentiality and control.
