Little Doctor: Hackers who want to gain access to popular chat applications to use the camera and user sound can do it very easily by using a worm published online.
At the moment it is still zero day which means that the security gap has not been fixed. 
The framework, named “Little DoctorIs a super weapon that can violate JavaScript-based chat applications. So many popular chat applications are at risk because of their architecture. Services that have been developed in Electron, or that contain a built-in webview, are in a very difficult position.
Let's mention that the Rocket Chat application provided a patch of 13 hours after revealing, and Ryver within a day. And the Slack application makes use of WebViews, however, it seems to be safe.
Australian hacker Shubham Shah and former co-worker Matt Bryant developed the framework worm and found an unpatched Microsoft Azure Storage Explorer zero day.
“This worm is cross-platform, and can steal files from any app that has access to the WebRTC APIs, and the Cordova APIs” said Moloch at Kiwicon hacking conference held in Wellington.
The team uncovered the error in Microsoft, but after 90 days, it did not receive a response.
The trio didn't stop there, having found and demonstrated the exploit in the Rocket Chat and Ryver apps, turning an attack cross-site scripting in remote code execution for container apps.
