The most watched YouTube clip of all time, along with other popular video clips, have been deleted or modified by replacing the cover image and changing the title. The main suspects are two groups of hackers called Prosox and Kuroi'sh
Together with Despacito, which has an apple of over 5 billion impressions, is the most watched YouTube clip ever seen, there have been temporary disappearances or songs from artists such as Shakira, Chris Brown, DJ Snake, Selena Gomez, Drake, Katy Perry and Taylor Swift
It's unclear whether hackers have gained clandestine access using a exploit that targets the entire YouTube portal, or just compromising the accounts attributed to those artists. But at least one of the hackers would have confirmed the use of a script to change the title of the clips.
