On Thursday, The Wall Street Journal reported that Yahoo Sports had been hacked, and that some users had their passwords reset.
Yahoo was not immediately available to comment on the reports.
The company said in a statement that it was “aware of reports that some Yahoo users may have been impacted by a data breach.”
Yahoo added that it is in the process of addressing these reports.
In the wake of the breach, Yahoo Sports has instituted new security measures, and is working with law enforcement, including the Federal Bureau of Investigation and the Department of Homeland Security, to help prevent further breaches.
According to The Journal, Yahoo is also offering an “emergency reset” service for all users who have used their accounts before the date of the report.
It’s unclear if the offer will be available to all users or just to those who have recently used their Yahoo accounts.
The WSJ also reported that the hackers managed to gain access to users’ passwords and email addresses.
In addition, it is not clear if Yahoo has shared those passwords with the FBI, as the WSJ stated it has.
The FBI declined to comment.
Yahoo has been facing increasing scrutiny over its cybersecurity following the revelations of a massive data breach in 2015 that exposed the personal information of as many as 11 million people.
