CANBERRA 鈥 In early 2018, in a complex of low-rise buildings in the Australian capital, a team of government hackers was engaging in a destructive digital war game.
The operatives 鈥 agents of the Australian Signals Directorate, the nation鈥檚 top-secret eavesdropping agency 鈥 had been given a challenge. With all the offensive cyber tools at their disposal, what harm could they inflict if they had access to equipment installed in the 5G network, the next-generation mobile communications technology, of a target nation?
What the team found, say current and former government officials, was sobering for Australian security and political leaders: The offensive potential of 5G was so great that if Australia were on the receiving end of such attacks, the country could be seriously exposed. The understanding of how 5G could be exploited for spying and to sabotage critical infrastructure changed everything for the Australians, according to people familiar with the deliberations.
Mike Burgess, the head of the signals directorate, recently explained why the security of fifth generation, or 5G, technology was so important: It will be integral to the communications at the heart of a country鈥檚 critical infrastructure 鈥 everything from electric power to water supplies to sewage, he said in a March speech at a Sydney research institute.
Washington is widely seen as having taken the initiative in the global campaign against Huawei Technologies Co Ltd., a tech juggernaut that in the three decades since its founding has become a pillar of Beijing鈥檚 bid to expand its global influence. Yet Reuters interviews with more than two dozen current and former Western officials show it was the Australians who led the way in pressing for action on 5G; that the United States was initially slow to act; and that Britain and other European countries are caught between security concerns and the competitive prices offered by Huawei.
The Australians had long harbored misgivings about Huawei in existing networks, but the 5G war game was a turning point. About six months after the simulation began, the Australian government effectively banned Huawei, the world鈥檚 largest maker of telecom networking gear, from any involvement in its 5G plans. An Australian government spokeswoman declined to comment on the war game.
After the Australians shared their findings with US leaders, other countries, including the US, moved to restrict Huawei.
The anti-Huawei campaign intensified last week, when President Donald Trump signed an executive order that effectively banned the use of Huawei equipment in US telecom networks on national security grounds and the Commerce Department put limits on the firm鈥檚 purchasing of US technology. Google鈥檚 parent, Alphabet, suspended some of its business with Huawei, Reuters reported.
Until the middle of last year, the US government largely 鈥渨asn鈥檛 paying attention,鈥 said retired US Marine Corps General James Jones, who served as national security adviser to President Barack Obama. What spurred senior US officials into action? A sudden dawning of what 5G will bring, according to Jones.
鈥淭his has been a very, very fast-moving realization鈥 in terms of understanding the technology, he said. 鈥淚 think most people were treating it as a kind of evolutionary step as opposed to a revolutionary step. And now that light has come on.鈥
The Americans are now campaigning aggressively to contain Huawei as part of a much broader effort to check Beijing鈥檚 growing military might under President Xi Jinping. Strengthening cyber operations is a key element in the sweeping military overhaul that Mr. Xi launched soon after taking power in 2012, according to official US and Chinese military documents. The US has accused China of widespread, state-sponsored hacking for strategic and commercial gain.
A THREAT TO CRITICAL INFRASTRUCTURE
If Huawei gains a foothold in global 5G networks, Washington fears this will give Beijing an unprecedented opportunity to attack critical infrastructure and compromise intelligence sharing with key allies. Senior Western security officials say this could involve cyber attacks on public utilities, communication networks and key financial centers.
In any military clash, such attacks would amount to a dramatic change in the nature of war, inflicting economic harm and disrupting civilian life far from the conflict without bullets, bombs or blockades. To be sure, China would also be vulnerable to attacks from the US and its allies. Beijing complained in a 2015 defense document, 鈥淐hina鈥檚 Military Strategy,鈥 that it has already been a victim of cyber-espionage, without identifying suspects. Documents from the National Security Agency leaked by American whistleblower Edward Snowden showed that the United States hacked into Huawei鈥檚 systems, according to media reports. Reuters couldn鈥檛 independently verify that such intrusions took place.
However, blocking Huawei is a huge challenge for Washington and its closest allies, particularly the other members of the so-called Five Eyes intelligence-sharing group 鈥 Britain, Canada, Australia and New Zealand. From humble beginnings in the 1980s in the southern Chinese boom town of Shenzhen, Huawei has grown to become a technology giant that is deeply embedded in global communications networks and poised to dominate 5G infrastructure. There are few global alternatives to Huawei, which has financial muscle 鈥 the company reported revenue for 2018 jumped almost 20% to more than $100 billion 鈥 as well as competitive technology and the political backing of Beijing.
鈥淩estricting Huawei from doing business in the US will not make the US more secure or stronger,鈥 the company said in a statement in response to questions from Reuters. Such moves, it said, would only limit 鈥渃ustomers in the US to inferior and more expensive alternatives.鈥
For countries that exclude Huawei there is a risk of retaliation from Beijing. Since Australia banned the company from its 5G networks last year, it has experienced disruption to its coal exports to China, including customs delays on the Chinese side. In a statement, China鈥檚 foreign ministry said it treated 鈥渁ll foreign coal equally鈥 and that to assert 鈥淐hina has banned the import of Australian coal does not accord with the facts.鈥
Tension over Huawei is also exposing divisions in the Five Eyes group, which has been a foundation of the post-Second World War Western security architecture. During a trip to London on May 8, US Secretary of State Mike Pompeo issued a stark warning to Britain, which has not ruled out using Huawei in its 5G networks. 鈥淚nsufficient security will impede the United States鈥 ability to share certain information within trusted networks,鈥 he said. 鈥淭his is exactly what China wants; they want to divide Western alliances through bits and bytes, not bullets and bombs.鈥
Huawei鈥檚 74-year-old founder, Ren Zhengfei, is a former officer in China鈥檚 military, the People鈥檚 Liberation Army. 鈥淢r. Ren has always maintained the integrity and independence of Huawei,鈥 the company said. 鈥淲e have never been asked to cooperate with spying and we would refuse to do so under any circumstance.鈥
In an interview with Reuters at the company鈥檚 headquarters in Shenzhen, Eric Xu, a deputy chairman, said Huawei had not allowed any government to install so-called backdoors in its equipment 鈥 illicit access that could enable espionage or sabotage 鈥 and would never do so. He said 5G was more secure than earlier systems.
鈥淐hina has not and will not demand companies or individuals use methods that run counter to local laws or via installing 鈥榖ackdoors鈥 to collect or provide the Chinese government with data, information or intelligence from home or abroad,鈥 the Chinese foreign ministry said in a statement in response to questions from Reuters.
Washington argues that surreptitious backdoors aren鈥檛 necessarily needed to wreak havoc in 5G systems. The systems will rely heavily on software updates pushed out by equipment suppliers 鈥 and that access to the 5G network, says the US, potentially could be used to deploy malicious code.
So far, America hasn鈥檛 publicly produced hard evidence that Huawei equipment has been used for spying.
Asked whether the US was slow to react to potential threats posed by 5G, Robert Strayer, the State Department鈥檚 lead cyber policy diplomat, told Reuters that America had long been concerned about Chinese telecom companies, but that over the past year, as 5G loomed closer, 鈥渨e were starting to talk more and more with our allies.鈥 Banning Huawei from 5G networks remains 鈥渁n end goal,鈥 he said.
THE TECH THREAT
The West has long harbored concerns about Chinese telecom equipment. In 2012, a US House Intelligence Committee report concluded Chinese tech companies posed a national security threat. Huawei denounced the finding.
Despite such concerns, the US government鈥檚 response to the threats posed by 5G only took shape more recently.
In February 2018, Malcolm Turnbull, then prime minister of Australia, flew to Washington DC. Even before Australia鈥檚 eavesdropping agency had run its war game, Turnbull was already raising red flags in Washington. A former technology entrepreneur, he believed 5G presented significant risks and wanted to press allies to act against Huawei.
鈥淗e was warning about how important 5G networks would be and the security risks we all needed to think about around countries that had capability, form and intent, as well as coercive laws,鈥 a senior Australian source told Reuters.
A spokesman for Mr. Turnbull declined to comment.
Mr. Turnbull and his advisers met US officials, including Kirstjen Nielsen, then US secretary of homeland security, and Michael Rogers, then head of the US National Security Agency, the US signals-intelligence operation. The Australians said they believed Beijing could compel Huawei to do its bidding and that this posed a threat should tensions with China rise in the future, said two of the Australian officials familiar with the meeting.
The US officials were receptive to the Australian message, but imposing restrictions on the world鈥檚 largest maker of mobile network gear didn鈥檛 appear to be a high priority, according to the two Australian officials. 鈥淭hey didn鈥檛 share our concern with the same urgency,鈥 said one.
Mr. Rogers declined to comment. A Department of Homeland Security official did not elaborate on the meeting, but said the agency works closely with Australia on security issues and that 鈥淐hina will continue to use cyber espionage and bolster cyber-attack capabilities to support its national security priorities.鈥
5G technology is expected to deliver a huge leap in the speed and capacity of communications. Downloading data may be up to 100 times faster than on current networks.
But 5G isn鈥檛 only about faster data. The upgrade will see an exponential spike in the number of connections between the billions of devices, from smart fridges to driverless cars, that are expected to run on the 5G network. 鈥淚t鈥檚 not just that there will be more people with multiple devices, but it will be machines talking to machines, devices talking to devices 鈥 all enabled by 5G,鈥 said Mr. Burgess, the Australian Signals Directorate chief, in his March address.
This configuration of 5G networks means there are many more points of entry for a hostile power or group to conduct cyber warfare against the critical infrastructure of a target nation or community. That threat is magnified if an adversary has supplied equipment in the network, US officials say.
Huawei said in its statement that the company does 鈥渘ot control in any way the networks in which our equipment is deployed by our clients. The US and Australian allegations are fanciful and are not rooted in any evidence at all.鈥
In July 2018, Britain delivered a blow to Huawei. A government-led panel that includes senior intelligence officials said it was no longer fully confident it could manage national security risks posed by the Chinese telecom equipment giant.
That panel oversees the work of a laboratory that was set up by the British government in 2010 and is funded by Huawei to vet the company鈥檚 equipment used in the UK. The facility was established because even then Huawei was perceived as a security risk. The oversight panel said serious problems it had identified with Huawei鈥檚 engineering processes 鈥渆xposed new risks in the UK telecommunication networks and long-term challenges in mitigation and management.鈥
That report was a 鈥渂ombshell,鈥 shaping how the Americans viewed the Huawei 5G risk, said one US official.
US officials also point to Chinese laws enacted in recent years that they say could compel individuals and companies to assist the Chinese government in conducting espionage.
China鈥檚 foreign ministry called this portrayal by US officials of Chinese legislation 鈥渁 misreading and a wanton smearing of relevant Chinese laws,鈥 adding: 鈥淭rying to smear others to wash oneself clean is futile.鈥
THE WEST AWAKES
Through the middle of last year, the Australians continued to apprise other countries of their worries about 5G. 鈥淲e were sharing our concerns about security with many allies, not just the US and not just the traditional partners,鈥 said one of the senior Australian officials. 鈥淲e shared our thoughts with Japan, Germany, other European countries and South Korea.鈥
In Washington, the administration began imposing restrictions on Huawei. In August, Trump signed a bill banning federal agencies and their contractors from using equipment from Huawei and ZTE Corp, another Chinese telecom equipment maker. Huawei has since filed a lawsuit in federal court in Texas challenging the ban.
In late August, the Australians went further: They banned companies that didn鈥檛 meet their security requirements, which included Huawei, from supplying any equipment for the country鈥檚 5G network, whether run by the government or by private firms.
Australia鈥檚 decision, China鈥檚 Foreign Ministry said in a statement, 鈥渉as no basis in fact, and is an abuse of 鈥榥ational security鈥 standards. China urges the Australian side to abandon Cold War thinking and ideological prejudices, and provide a fair, transparent, non-discriminatory environment for Chinese companies.鈥
In November, New Zealand鈥檚 intelligence agency blocked the country鈥檚 first request by a telecom service provider to use Huawei kit for a 5G network, citing national security concerns.
Like the Australians and Americans, British security officials had concerns over China鈥檚 potential use of Huawei as a channel for conducting espionage. But the options are limited. Huawei is one of only three major global companies that analysts say can supply a broad range of advanced mobile network equipment at scale. The other two are Ericsson and Nokia. And Huawei has a reputation among telecom operators for supplying cost-effective equipment promptly.
Nevertheless, British security officials were becoming increasingly frustrated with what they viewed as Huawei鈥檚 failure to fix software flaws in its equipment, particularly discrepancies in the source code 鈥 the programs鈥 underlying set of instructions. This problem means the laboratory near Oxford set up to vet Huawei equipment can not even be sure that the code it is testing is exactly the same as the code Huawei deploys in its real-world equipment. This makes it difficult to provide safety assurances about the company鈥檚 gear.
British officials say the array of flaws could be exploited by China, as well as other malevolent actors. Ian Levy, a British security official who oversees the UK鈥檚 review of Huawei equipment, told Reuters the company鈥檚 software engineering is like something from 20 years ago. 鈥淭he chance of a vulnerability with a Huawei piece of kit is much higher than other vendors,鈥 he said.
The company said it has pledged to spend at least $2 billion 鈥渙ver the next five years鈥 to improve its software engineering capabilities.
British ministers have agreed to allow Huawei a restricted role in building parts of its 5G network, but the government has yet to announce its final decision. The European Union has left it to individual governments to decide whether to ban any company on national security grounds. Some European security officials say banning one supplier doesn鈥檛 address the broader issue of the risks posed by Chinese technology in general.
HUAWEI FIGHTS BACK
As the tensions between the West and Huawei intensified through last year, they suddenly took a personal turn. US law enforcement officials had for some time been investigating links between Huawei and Iran, including the involvement of Meng Wanzhou, Huawei鈥檚 chief financial officer, who is the daughter of the company鈥檚 founder. The probe followed Reuters stories in 2012 and 2013 that revealed links between Huawei, Ms. Meng and another company that allegedly attempted to violate US sanctions on Iran.
When US officials became aware that Meng would be traveling through Vancouver in December, they pounced, asking Canada to detain her on allegations of bank and wire fraud. Ms. Meng remains free on bail in Canada while the US government tries to have her extradited. Huawei said in its statement that Ms. Meng 鈥渋s not guilty of the charges she faces,鈥 and that they are 鈥減olitically motivated.鈥
The Huawei conflict isn鈥檛 only about US-China superpower rivalry: The activities of Ms. Meng and Huawei were under scrutiny by US authorities long before Mr. Trump began a trade war with China, according to interviews with people familiar with those probes. But there is no doubt the wider showdown with Huawei has now become intensely geopolitical.
In recent months, the US has ramped up diplomatic efforts to urge allies to sideline Huawei. 5G is a 鈥済ame-changing technology with implications across all aspects of society from business, government, military and beyond,鈥 Gordon Sondland, US ambassador to the European Union, told Reuters in February. 鈥淚t seems common sense to me to not hand over the keys to your entire society to an actor that has 鈥 demonstrated malign conduct.鈥
Asked whether there is evidence of Huawei equipment having been used for espionage, Mr. Sondland said 鈥渢here is classified evidence.鈥 He declined to expand on the nature of the material beyond saying there was no doubt that Huawei had 鈥渢he capability to hack a system鈥 and 鈥渢he mandate by the government to do so upon request.鈥
Mr. Pompeo has publicly gone further than most US officials by directly linking the company to Beijing. 鈥淗uawei is owned by the state of China and has deep connections to their intelligence service,鈥 he said in March. 鈥淭hat should send off flares for everybody who understands what the Chinese military and Chinese intelligence services do.鈥
Huawei has repeatedly denied it is controlled by the government, military or Chinese intelligence services. 鈥淯S Secretary of State Pompeo is wrong,鈥 the company said in its statement, adding that it is owned by its employees.
While Huawei was initially muted in its public response, it too has become more combative. In late February, the company confronted the US at a major annual gathering of mobile industry executives in Barcelona, where Huawei鈥檚 red logo was ubiquitous. Top American officials arrived intent on warning government and industry representatives off Huawei. But the company had flown in a team of senior executives to offer customers and representatives of European governments reassurance in the face of the US accusations.
In a keynote speech, Guo Ping, a deputy chairman at Huawei, took aim at America鈥檚 own spying operations. 鈥淧rism, Prism on the wall. Who鈥檚 the most trustworthy of them all?鈥 he said. Mr. Guo was referring to a mass US foreign-surveillance operation called Prism that was disclosed by former NSA contractor Mr. Snowden. The barb drew laughter from the audience.
Europeans pushed back, too. During one closed-door session, senior representatives from European telecom operators pressed a US official for hard evidence that Huawei presented a security risk. One executive demanded to see a smoking gun, recalled the US official.
The American official fired back: 鈥淚f the gun is smoking, you鈥檝e already been shot. I don鈥檛 know why you鈥檙e lining up in front of a loaded weapon.鈥 鈥 Reuters
