Internet experts have questioned how the Communist Party of China uses loophole monitoring to intercept calls made by MOBILE phone users in the Us

The Communist Party of China (CPC) is suspected of targeting, tracking and intercepting the calls of tens of thousands of US mobile phone users through Caribbean networks and exploiting decades-old vulnerabilities in global telecommunications networks, a US mobile phone security expert has questioned after analyzing sensitive signal data, the Guardian reported on Tuesday.

“Signalling” is the phrase “Signalling message” whereby a telecommunications operator sends orders across a global network without the owner’s knowledge; It allows telecommunications to negotiate mobile phones for subscribers, connect to other mobile phone users and assess roaming charges, but may be used for illegal purposes such as tracking, monitoring or intercepting communications.

Gary Miller, a former head of mobile network security in Washington state, suspects the Chinese Communist Party is using a government-controlled operator of mobile networks to send signalling messages to US users travelling abroad. He found that China carried out the most surveillance attacks on U.S. mobile phone users over 3G and 4G networks in 2018, most of which involved China Unicom, and questioned the likelihood of a government-sponsored spying campaign. He also mentioned that some users who appeared to be targets of China Unicom were also targets of two carriers in Barbados and the Bahamas.
