Here, we would like to add that the YouTube didn't get hacked but one of the biggest YouTube account or channel Vevo, which is a Sony Music Company video uploading channel, got hacked.
On April 4, as Twitterati searched for news regarding the shooting at the YouTube headquarters in the U.S., hackers compromised a verified employee's Twitter account to spread fake news in the midst of the attack.
The most-viewed video of all time on YouTube, Despacito, wasn't quite itself earlier today. All the video images have been altered and are now replaced with a still from the Netflix show - Casa de Papel, which shows a masked-gang holding firearms.
Lots of other popular music videos have also defaced, including songs from Chris Brown, Shakira, DJ Snake, Selena Gomez, Drake, Katy Perry, and Taylor Swift. Among the affected music videos was Luis Fonsi and Daddy Yankee's Despacito, which now holds the title for YouTube's most viewed video of all time, coming in at over five billion views. Now, reports are coming that all of the videos are back again but the impact is on news now. It's also not clear if the hackers have gained access to the individual accounts or if there has been a widespread exploit with the Vevo accounts. The next incident may be less of a prank (as this appears to be) and more of a malicious campaign. We are working to reinstate all videos affected and our catalog to be restored to full working order.
"We are continuing to investigate the source of the breach", spokesperson Anthi Pantelidis said in an email.
The hackers are claiming they used a "script" for the hack.
"To upload and alter video content with code you should require an authorisation token", he said.
