NEW YORK (AP) — TikTok said Tuesday it has taken steps to stop a cyberattack targeting high-profile accounts,Zopes 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 prepared statement. TikTok has been working with CNN to restore its access to the account and add “enhanced security measures” to safeguard it, Grosse said.

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

CNN did not immediately reply to a request for comment.

The social media company said the attack took place through the platform’s direct-messaging feature, without sharing further information about the nature of the hack. Grosse said TikTok is still investigating the “potential exploit” and working with affected account owners who need their access restored.

TikTok did not name the other affected accounts, other than to note that the account of socialite and reality TV star Paris Hilton was targeted but not compromised.
