In all these circumstances, the researchers submitted vulnerabilities to Electron to get them fastened, which earned them greater than $10,000 in rewards. The bugs have been fastened earlier than the researchers revealed their analysis.

Within the case of Discord, the bug Purani and his colleagues discovered solely required them to ship a malicious hyperlink to a video.

In each circumstances, if the targets clicked on these hyperlinks, hackers would have been in a position to take management of their computer systems, Purani defined within the discuss.

“If you’re extra paranoid, I like to recommend utilizing the web site itself as a result of then you could have the safety which Chromium has, which is far bigger than the Electron,” Purani mentioned.
Nonetheless, Purani mentioned that it’s a very good factor to have Electron underlie so many apps as a result of “when you’ve got only one framework, which is working all of the apps, then you’ll be able to simply give attention to hardening that very same framework.”
For him, one of many most important takeaways of their analysis is that Electron is dangerous exactly as a result of customers are very prone to click on on hyperlinks shared in Discord or Microsoft Groups.
