The video for the hit song Despacito, which has more than five billion views on Youtube has been hacked.
Several other music videos of artists posted on Youtube by music hosting service Vevo including: Shakira, Selena Gomez, Drake and Taylor Swift, were also affected by the attack.
The clip's original cover image was replaced with a photo showing a group of persons wearing masks and pointing guns.
The video was temporarily brought down by Youtube until the problem was fixed.
The hackers who call themselves Prosox and Kuroi'sh, had substituted some of the videos titles with their own messages including a call to "free Palestine" alongside their own nicknames.
A spokeswoman of Youtube told the press that after they notice an unusual upload activity on a handful of Vevo channels, they swiftly disabled access while they initiated investigation.
Vevo said "We are working to reinstate all videos affected and our catalogue to be restored to full working order. We are continuing to investigate the source of the breach."
A Twitter account that apparently belonged to one of the hackers had posted: "It's just for fun, I just use [the] script 'youtube-change-title-video' and I write 'hacked'."
"Don't judge me I love YouTube," it added.
Cyber-security expert Prof Alan Woodward, from Surrey University, said it was unlikely that the hacker had been able to gain access so easily.
"To upload and alter video content with code you should require an authorisation token," Woodward added.
"So, either this hacker has found a way around that need for authorisation, or they are being economical with the facts, or they obtained the permissions in some other way."
