TikTok data breach claims put ByteDance’s short video app back in spotlight amid controversy over Chinese ownership
- Cybersecurity analysts tweeted about the discovery of an insecure server on Monday, but claims of leaked personal data are inconclusive
- TikTok said claims about the breach were incorrect and that the code was ‘completely unrelated’ to its back-end source code

TikTok said the claims of a breach discovered over the weekend were incorrect. “Our security team investigated this statement and determined that the code in question is completely unrelated to TikTok’s back-end source code,” a spokesperson said.
Troy Hunt, an Australian web security consultant, went through some of the data samples listed in the leaked files and found matches between user profiles and videos posted under those IDs. But some details included in the leak were “publicly accessible data that could have been constructed without breach”.
“This is so far pretty inconclusive; some data matches production info, albeit publicly accessible info. Some data is junk, but it could be non-production or test data,” he posted on Twitter. “It’s a bit of a mixed bag so far.”
The vulnerability identified by Microsoft is a narrower issue that could have affected mobile phones running Android. It may have allowed attackers to access and modify “TikTok profiles and sensitive information, such as by publicising private videos, sending messages and uploading videos on behalf of users,” wrote Dimitrios Valsamaras from the Microsoft 365 Defender Research Team.
A TikTok spokesperson said the company had responded quickly to Microsoft’s findings and fixed the security flaw, which was found “in some older versions of the Android app”.
However inconclusive or small the issues may be, there will be intense focus on TikTok and its parent firm at a time when the US may step up its measures against businesses with links to China. In June, nine US senators wrote a public letter to TikTok’s chief executive officer asking him to explain alleged security breaches.
President Joe Biden is expected to sign an executive order that would restrict US investment in Chinese tech companies and separate action targeting TikTok is a possibility, with the administration paying close attention to whether the Chinese government has access to American customer data. The company has told US lawmakers that it has taken steps to protect that data through a contract with Oracle Corp.
“There’s a lot of attention on the way TikTok operates and there’s a big gap between how it operates and how it says it operates,” said Robert Potter, co-CEO of Australian-US cybersecurity firm Internet 2.0 Inc.
In July, Potter’s team said in a report that it had found “excessive data harvesting” carried out by TikTok on user devices, that the app checks device location at least once an hour and it has code that collects serial numbers for both the device and the SIM card.

The report received wide attention in Australia, and Clare O’Neil, the new Minister for Home Affairs, announced on Monday that she has ordered her department to investigate what data TikTok acquires and who can access it.
“We’ve got this basic problem here where we’ve got technology companies that are based in countries with a more authoritarian approach to the private sector,” O’Neil said in emailed remarks. “TikTok is not the beginning and the end of this. It’s one of the very large number of issues that’s given rise to by these very dominant technology companies and the role they are playing in our lives.”
