According to a recent report by The Wall Street Journal, two years before the credit agency Equifax suffered one of the biggest data breaches in history, the company was hit by a possible cyberespionage-linked theft of confidential business information by former employees.

All the former employees believed to have participated in the alleged theft were suspected to have connections to the Chinese government, though the WSJ noted that U.S. law enforcement authorities did not have enough evidence to definitively make that determination.
