A significant vulnerability discovered in China's WeChat app was successfully patched through collaboration between a US security company and Tencent. This incident, where the US company shared technical information with Tencent, highlights the importance of private sector actors working together to secure global systems, despite the challenging geopolitical climate.
“It was notable a few weeks ago, there was an incident where a major vulnerability was found in WeChat, which is a super app in China that everyone uses to communicate and conduct daily life in China. A US security company actually found a vulnerability in WeChat that if left undetected and exploited could have wiped out the entire hundreds of millions of devices using WeChat, not just in China, but around the world.”
“This US security company actually went to TenCent, and together they collaborated on patching mitigating the vulnerability.”
“That's an important example of non-government, non-state private actor collaboration, sharing technical information behind the scenes to make systems more secure that don't stop at state borders. And that's the kind of thing that I think needs to continue to happen and has been really hard because of the current geopolitical situation.”
