Revealed: China Suspected of Spying on Americans via Caribbean Phone Networks

Security expert claims Chinese surveillance may have affected tens of thousands of Americans

The Guardian UK, 15 DEC 2020.

China appears to have used mobile phone networks in the Caribbean to surveil US mobile phone subscribers as part of its espionage campaign against Americans, according to a mobile network security expert who has analysed sensitive signals data.

The findings paint an alarming picture of how China has allegedly exploited decades-old vulnerabilities in the global telecommunications network to route “active” surveillance attacks through telecoms operators.

The alleged attacks appear to be enabling China to target, track, and intercept phone communications of US phone subscribers, according to research and analysis by Gary Miller, a Washington state-based former mobile network security executive.

Miller, who has spent years analysing mobile threat intelligence reports and observations of signalling traffic between foreign and US mobile operators, said in some cases China appeared to have used networks in the Caribbean to conduct its surveillance.

At the heart of the allegations are claims that China, using a state-controlled mobile phone operator, is directing signalling messages to US subscribers, usually while they are travelling abroad.

Signalling messages are commands that are sent by a telecoms operators across the global network, unbeknownst to a mobile phone user. They allow operators to locate mobile phones, connect mobile phone users to one another, and assess roaming charges. But some signalling messages can be used for illegitimate purposes, such as tracking, monitoring, or intercepting communications.

US mobile phone operators can successfully block many such attempts, but Miller believes the US has not gone far enough to protect mobile phone users, who he believes are not aware of how insecure their communications are.

Miller focused his research on messages that he said did not appear legitimate, either because they were “unauthorised” by the GSMA, an international standard-setting body for the telecommunications industry, or because the messages were sent from a location that did not match where a user was travelling.

Miller recently left a job at Mobileum, a mobile security company that tracks and reports threats to mobile operators, to start Exigent Media, a cyberthreat research and media firm. He said he was sharing his findings with the Guardian to help expose “the severity of this activity” and to encourage the implementation of more effective countermeasures and security policies.

“Government agencies and Congress have been aware of public mobile network vulnerabilities for years,” he said. “Security recommendations made by our government have not been followed and are not sufficient to stop attackers.”

He added: “No one in the industry wants the public to know the severity of ongoing surveillance attacks. I want the public to know about it.”

At Mobileum, Miller was vice-president of solutions for network security and risk products, a role he said gave him access to information about threats on mobile networks around the world.

Miller said that he found that in 2018 China had conducted the highest number of apparent surveillance attacks against US mobile phone subscribers over 3G and 4G networks. He said the vast majority of these apparent attacks were routed through a state-owned telecoms operator, China Unicom, which he said pointed in very high likelihood to a state-sponsored espionage campaign.

Overall, Miller said he believed tens of thousands of US mobile users were affected by the alleged attacks emanating from China from 2018 to 2020.

“Once you get into the tens of thousands, the attacks qualify as mass surveillance, which is primarily for intelligence collection and not necessarily targeting high-profile targets. It might be that there are locations of interest, and these occur primarily while people are abroad,” Miller said. In other words, Miller said he believed the messages were indicative of surveillance of mass movement patterns and communication of US travellers.

Miller also found what he called unique cases in which the same mobile phone users who appear to have been targeted via China Unicom also appear to have been targeted simultaneously through two Caribbean operators: Cable & Wireless Communications (Flow) in Barbados and Bahamas Telecommunications Company (BTC).

The incidences, which occurred dozens of times over a four to eight-week period, were so unusual that Miller said they were a “strong and clear” indicator that these were coordinated attacks.

At the same time, Miller said that in 2019 most apparent attacks against US subscribers over the 3G network emanated from Barbados, while China significantly reduced the volume of messages to US subscribers.

“China reduced attack volumes in 2019, favouring more targeted espionage and likely using proxy networks in the Caribbean to conduct its attacks, having close ties in both trade and technology investment,” Miller said.
