Here is a Fortinet PDF for the Is my toothbrush really smart? presentation by Axelle Apvrille at Troopers in 2018. I suspect this information is what they are referencing in the article.
In my earlier thread I should have recommended that folks be on the lookout for end of life(EoL) versions of Electron that are bundled with software that is itself updated to the latest version. I've observed a case where fully updated software was using Electron 22.x.x that isn't EoL yet, but will be in 2 weeks. In those cases I strongly suggest you notify your vendor and, if it is paid software, pressure them to migrate to a supported version ASAP.
Note: There IS a patched version of 22.x.x which is 22.3.24.
I can confirm that a fresh install of Keybase on macoS is using Electron 22.1.0 which has not been patched and will go EoL on October 10. I find this very concerning from security software.
I can also confirm that a fresh install of Microsoft Teams on macOS is using Electron 19.1.8 which has not been patched and went EoL last November. A note that 19.1.9 is the last version of this train and includes at least two security fixes.
Roughly 2 weeks ago Google patched a critical vulnerability, CVE-2023-4863, that was being exploited in the wild. The broad impact of the root cause of the vuln and the fact that it will have a long tail of unpatched software has been poorly communicated. You can read more in @dangoodin 's excellent article on Ars Technica.
As pointed out in the article above, Electron is based on Chromium and is impacted. Electron is bundled in a ton of apps that people might overlook.
I threw together the following shell command to help macOS audit which versions of Electron apps are installed.
find /Applications -type f -name "*Electron Framework*" -exec \ sh -c "echo \"{}\" && strings \"{}\" | grep '^Chrome/[0-9.]* Electron/[0-9]' | head -n1 && echo " \;
When run, you should see something similar to the following:
/Applications/Visual Studio Code.app/Contents/Frameworks/Electron Framework.framework/Versions/A/Electron Framework Chrome/114.0.5735.289 Electron/25.8.1
