Yes, the agency’s analysts told the White House, it is possible that Chinese intelligence authorities could intercept data or use the app to bore into smartphones. But there is no evidence they have done so, despite the calls from President Donald Trump and Secretary of State Mike Pompeo to neutralise a threat from the app’s presence on millions of American devices.
It made little difference. When Trump issued an executive order Thursday that would effectively ban TikTok from operating in the United States in 45 days — part of an effort to force a sale of the app to an American company, most likely Microsoft — he declared it threatened “the national security, foreign policy and economy of the United States.”
In a surprise addition, he issued a similar ban on WeChat, a Chinese social media app on which millions of people, largely outside the US, conduct everyday conversations and financial transactions.
There is no doubt the actions by the administration are the toughest since it took steps last year to block the use of Huawei telecommunications equipment by American companies. And there is a fear running through Silicon Valley that Trump — seen as eager to punish the Chinese, and as angry at viral TikTok videos that mock him and at the app’s role in deterring attendance at his rally in June in Tulsa, Oklahoma — is opening the door for countries around the world to declare Facebook and Google to be similar threats to their own security.
Measuring national security threats has always been tinged as much by politics as intelligence assessments: Think of John F Kennedy’s warning of the “missile gap” with the Soviets in the 1960 election, or George W Bush’s declaration of an imminent Iraqi nuclear ability on his ill-fated march to war 17 years ago.
Trump’s warning about the Chinese threat has been expanding: Days before the executive order, the State Department announced a “Clean Network” initiative, threatening to ban not only apps, but Chinese undersea cables, telecommunications firms that have operated in the US for years and businesses that store information in the cloud.
Sorting out the real threats from the imagined ones is as complex as the design of the internet. But the threat TikTok poses, intelligence officials say, pales to the one created by Huawei, the Chinese telecommunications giant that was seeking to wire up the US, Europe and much of the developing world, using the transition to 5G networks to control global communications.
“Is TikTok a problem?” Sen. Mark Warner, D-Va, the ranking member of the Senate Intelligence Committee, said Thursday at the Aspen Security Forum.
“Yes, but on the hierarchy of problem we are talking about, an app that allows you to make funny videos” does not really rank, he said.
Huawei is a far deeper concern, Warner said, because it seeks to rebuild internet infrastructure — putting in the switches and cell towers on which American communications run. In the 5G era, that will also be the infrastructure on which manufacturing, gas supply lines, agriculture and self-driving cars operate. In a time of conflict, China could, in theory, order the systems shut down or subtly manipulated.
Even so, through much of last year, Trump talked about Huawei as a card in trade negotiations, undercutting his own aides, who were pressing allies to ban China’s products.
That has changed since the president began blaming China for spreading the coronavirus. And recent events — like the drying up of Chinese supplies for dealing with the pandemic and the crackdown by China against the pro-democracy movement in Hong Kong — have persuaded allies like Britain to reverse course and ban Huawei’s presence in their networks.
But allies seem unlikely to get as exercised about TikTok. No one is saying that it can bring the US economy or the NATO alliance to its knees — though it can lead to a lot of dinner table arguments over the time and attention it has sucked away from other things.
That does not mean there is no threat. There are worries about the location-identifying elements of TikTok, which is why the US military and intelligence agencies have banned it from official phones and discouraged its use on personal phones. There is concern about what other data it could, in theory, pull from the phones.
If Huawei’s installation of equipment around the world poses a high risk, and TikTok a comparatively low one, WeChat, according to other officials, presents a more acute — though limited — problem.
US officials believe that China has the ability to monitor communications on the communications platform.
WeChat is not widely used in the US, except by one key group — Chinese-born software engineers in Silicon Valley and other high-tech workforces, according to US officials. They use WeChat to collaborate on tough mathematical, software or engineering problems, trading solutions back and forth. Proprietary data can be scooped up by Chinese intelligence services, a US official said.
Christoph Hebeisen, director of security intelligence research at Lookout, a company that focuses on the security of mobile devices, examined the TikTok app and came to a conclusion close to that of the intelligence agencies: The Chinese government does not seem to have access to the company’s data on American users, but it could probably get it if it wanted to.
But he said that he thought that was not too much different than if the US government obtained a Foreign Intelligence Surveillance Act warrant to get the data of an American social media company.
“If you are China, you probably don’t want your government officials to have Facebook on their phones,” he said, “and if you are the US, you probably don’t want your government officials to have TikTok.”
