Demand for WA "debugging" services on the rise: security firms October 2, 2014
A spokesman from Perth-based Alpha Investigation Services said "bugs" could be minute physical listening devices that lasted three or four days in situ or could be operated electronically through mobile phones to listen in remotely.
He said investigators used sophisticated equipment to uncover listening devices in homes, businesses and cars.
"Bugs aren't necessarily a small thing. You aren't looking at a spy situation like you see in the movies. Bugs can be on anybody's phone...They are not easily found and it's not necessarily a physical thing on the phone," he said.
He said the company had been called in to sweep a lawyer's office in the past, but conducted criminal checks on all clients if they requested a debugging service "just in case".
