News Corp., the parent company of Fox News, The Wall Street Journal, and several other news outlets, said that hackers were inside its network for nearly two years and made off with private documents and emails.

News Corp. first disclosed the breach in February 2022, in a filing with the Securities and Exchange Commission and an article in The Wall Street Journal. The company said at the time that it discovered “persistent cyberattack activity” a month earlier in a third-party cloud service it used. Security firm Mandiant, which aided News Corp. in investigating the intrusion, told the WSJ it believed the attack was conducted by a threat actor aligned with the Chinese government.

Last week, News Corp. sent a breach notification letter to at least one affected employee that provided additional details.
