I don't know why the article doesn't link to the app, so the link is here
The article mentioned Check Point's app a dozen times but didn't bother to link it. So here its is Check Point - Certifi-gate Scanner
I also had Team Viewer installed on my Moto X (2013, Verizon) but I uninstalled it and then ran the app. My device is not vulnerable
These exploits and security lapses are becoming more frequent and widespread. I hope Google makes the demand that Android devices need to support rolling updates to allow Google to quickly patch these security vulnerabilities. Carriers need to get on board otherwise I think you might see an industry shift away from Android, at least amongst Corporate and enthusiast users.
This is the app made by the company who found the vulnerability: Certifi-Gate Scanner
I haven't checked yet hoping I will find someone else who has, honestly if someone is going to format their phone, they are the best candidate to try it.
