Stay Safe!

Most of the times, it’s the shady apps/malware that result in the hacks. Users unknowingly download such apps that easily gain access to camera and mic. The app/malware gives away all the personal information to a hacker who then leaks it.
Remember! Always download apps from the official app store or trusted sources.

Other times, videos are directly recorded by the person you’re communicating with using a screen recorder app and leaked.
So please make sure the person you are video chatting with is 100% trustworthy.
