The US Justice Department is working with Elon Musk's X/Twitter to identify those behind an attempted password-recovery attack that targeted hundreds of thousands of users this week, US Attorney General Todd Blanche said on Wednesday.
Blanche said in a statement on X that "sophisticated cyber criminals" attempted the attack, but the platform was able to disrupt it.
He did not provide further details about the incident.
A password-recovery attack generally involves attempts to gain access to online accounts by exploiting the "forgot password" or account-recovery process.
X did not immediately respond to a request for comment.
