A Parachute in the Pipes
When the Soviets built a new embassy in DC, US Tech Ops embedded bugs in the walls and this device in a drain pipe. Then they waited for a storm.
The rain masked the noise of a tiny blast triggered in the device, releasing a parachute connected by wires to the hidden bugs. It washed out through the pipe, where an agent linked the wires to a listening post. Success... until FBI traitor Robert Hanssen told the KGB. |
