Countering Maritime Espionage in Visakhapatnam

A private maritime logistics firm in Visakhapatnam found that ship-to-shore communication logs, docking schedules, and cargo manifests were being intercepted.

The client needed a high-authority espionage detection operation across port-side executive offices and the main coordination center.

Vizag port is saturated with radar, marine radio, and satellite activity, making low-power surveillance devices difficult to isolate.

• Audio transmitter detection within heavy marine VHF traffic.
• Threats for corporate assets including sensitive cargo exposure and sanctions risk.
• Potential concealment inside ruggedized marine radio or monitoring hardware.

Wahid Shaikh supervised the Maritime Shield operation using differential signal analysis and hardware-centric inspection of port infrastructure.

• Real-time spectrum analysis to separate authorized marine signals from unauthorized exfiltration.
• Physical line inspection of cable terminations and communications infrastructure.
• NLJD scanning of operations-room hardware and safety equipment.

The team uncovered a modified network router containing an illicit wireless bridge inside the server room overlooking the port.

The device intercepted unencrypted traffic and relayed it to a nearby fishing vessel equipped with a high-gain antenna.

• Replaced network equipment with verified clean hardware and tamper-evident seals.
• Installed a 24/7 RF monitoring station for anomalous signal alerts.
• Revamped communications protocols and operational security procedures.

The firm secured its logistics chain and restored confidence around the movement of sensitive civilian and defense-adjacent cargo.
