N. Korea’s new “spectrum analyzer” may be a surveillance tool

North Korea has allegedly developed its own version of what is called a “spectrum analyzer.” Daily NK sources suspect that the device, which was presented as a “Top 10 tech product” at the “2019 National Information Technology Advancement Exposition,” could be used to spy on North Korean citizens.

On Monday, Daily NK spoke to an expert in the field of radio waves, who asked to remain anonymous. “It’s essentially possible to detect and track wireless signals – frequencies – with a spectrum analyzer,” he said.

Simply explained, a spectrum analyzer is a piece of electronic equipment which measures the magnitude of known and unknown input signal set against the full frequency range of the instrument.

The specialist was not able to determine how advanced North Korea’s latest development really is. Nevertheless, he thought it’s possible the device “might even be used to wiretap calls on mobile phones.”

Other experts also agreed that the analyzer could be capable of detecting data transmission signals, which most North Koreans send out during a wireless communication.

It’s no secret that the state has long been intercepting the wireless communications devices of its citizens. Most surveillance equipment was previously imported from abroad. Now, however, North Korea has apparently managed to develop and manufacture similar instruments of its own. ......
