Youtube server has been hacked! I Youtube

Google's video sharing site Youtube servers are being hacked. Video disappeared from several nominating YouTube channels and some cover images and related text of some videos were changed. In place of the cover image of those videos, other images have been placed by the cyber attackers as their thumbnails.
The most recent video ever seen in YouTube's history, the Despacito song (music video) disappeared from YouTube after the attack. Hackers are introducing themselves as (Prosex and Kuroi'sh).

Not only Despasito, Hackers have changed the thumbnail / text of some music videos of Chris Brown, DJ Shake, Shakira, Selina Gomez, Drake, KT Perry and Taylor Swift. Some of these videos are still on YouTube but some disappear again.
Video hosting service Vivo started working on recovering a number of YouTube videos after Vivo was attacked. On Twitter, one claimed that he was able to write a script and change the title of the video on YouTube by writing that script. They tweeted to target other popular YouTube channels
But subsequently the videos again started to return to YouTube properly. In this regard, YouTube said that they suspend the uploading activities on some channels of Vivo by seeing unusual uploads in the channels and start searching the subject with the channel. That is, now the YouTube authorities are aware of the hacking incident.
