(New York) TikTok announced Tuesday that it had taken steps to stop a cyberattack targeting high-profile accounts, including one belonging to CNN.

“Our security team was recently alerted to malicious actors targeting CNN’s TikTok account,” TikTok spokesperson Jason Grosse said in a statement. TikTok worked with CNN to restore its access to the account and add “enhanced security measures” to protect it, Grosse said.

“We are committed to maintaining the integrity of the platform and will continue to monitor any further inauthentic activity,” he added.

CNN did not immediately respond to a request for comment.

The social media platform said the attack occurred through TikTok’s direct messaging feature, without sharing further details about the nature of the hack. Grosse said TikTok was still investigating the “potential exploit” and working with the owners of the affected accounts who need to restore their access.

TikTok did not provide the names of the other affected accounts, but indicated that reality TV star Paris Hilton’s account was targeted, but not compromised.
