TikTok says it is addressing a cyber-attack that targeted several brands and celebrities, BBC reported.
The video-sharing app, which is owned by Chinese company ByteDance, told the BBC that a "very limited" number of accounts had been compromised.
It added that it was working with users to restore access to their accounts.
TikTok did not share further details on the perpetrators of the cyber-attack, or how it was carried out.
One of the compromised accounts belonged to news outlet CNN.
"We have been collaborating closely with CNN to restore account access and implement enhanced security measures to safeguard their account moving forward," a TikTok spokesperson said.
TikTok said the account of reality TV star Paris Hilton was also targeted, but it was not compromised.
