After synthesizing information, along with hearing from a few brothers, this is my opinion. This event has taken place in the world since a few months ago, this time in Vietnam has just emerged. Reference link: https://www.businessinsider.com/youtube-channels-bitcoin-scammers-twitter-hack- 2020-8 At first, I thought that an email role manager of those channels was lost, leading to a series of channels being livestreamed (same artist). But then determined not to. Because the NBC News channel is also present (see photo).. Then it will be inferred that the YouTube part has a bug that makes the "hacker" "read back" the livestream key in some way, and get that key. live up. But continuing to number 3 is also incorrect. Because custom streams are titled, photo ---> related to YouTube's Live Event functionality, not a straight live stream. So now it's only possible that "hackers" gain access to the page or through a 3rd party gain control of the channel's Live feature. After seeing that you are sharing about how to prevent it by blocking the channel Restream.Ah! Then I dimly understand that the weakness comes from restream.io - a party that helps users to livestream at the same time on many different platforms. Need to verify from the parties. Because I don't have the right to manage "hacked" accounts, as well as I no longer use many YouTube-related tools -> lazy to check. But I think this direction is 80% sure. The reason why? Restream ask for permission to manage live stream (YouTube Stream Now) or live event (YouTube Live Event) always (see photo)Restream has the right to access your information when you allow access to your Google account (also see photo)Ok , when you allow so, then through restream, you can set up a new live, create a title, thumbnail, choose a topic, etc., without having to have access to a Google account to manage the channel.
