"In that respect then, it is in itself, nothing much to worry about for the video hosting site, though it does suggest that the defacement of videos is not technically hard to achieve, given the number of high profile artists that have been targeted".
On April 4, as Twitterati searched for news regarding the shooting at the YouTube headquarters in the USA, hackers compromised a verified employee's Twitter account to spread fake news in the midst of the attack. The video's image was altered and replaced with a masked gang holding guns (from Netflix show Casa de Papel), and the description was changed by hackers calling themselves Prosox and Kuroi'sh. At least one of the hackers claim that they used a "script" to alter the video titles.
Many other popular super hit music videos have been affected, including songs from Chris Brown, Shakira, Selena Gomez, Drake, Katy Perry and Taylor Swift. The defacement includes titles of the videos being changes to include the names of the hackers, the cover image changed, however, most of the content of videos remained unchanged. The video, which has been viewed over five billion times, has since reappeared on Fonsi's Vevo-linked YouTube account.More news: 257 dead as Algerian aircraft crashes near capital

Among the videos affected was "Despacito" by Luis Fonsi, which is now the most-watched YouTube video of all time, with more than five billion views.
A spokesperson at Vevo confirmed the cyberattack in a statement to the Daily Dot. "We are working to reinstate all videos affected and our catalogue to be restored to full working order".
Meanwhile, now it appears that all videos are back to normal as a YouTube's spokesperson said; "After seeing unusual upload activity on a handful of Vevo channels, we worked quickly with our partner to disable access while they investigate the issue". Overall, the hacker did it and they were out without leaving any trace so far.
