Report: Equifax Suffered Undisclosed Cyberattack Before Hack That Exposed 143 Million Consumers

Equifax reportedly fell victim to another cyber attack before the hack that exposed the personal info of 143 million people, according to a report from Bloomberg.

Bloomberg reports that Equifax, the consumer credit-reporting agency subject to a massive data-breach that possibly affected 143 million people, reportedly suffered another cyberattack in March that the company failed to disclose.

Equifax reportedly hired the security firm Mandiant to investigate both breaches and may have believed they had secured their systems until the second reported data breach.

Equifax said in a statement that it only became aware of the data breach impacting 143 million people on July 29 after data had already been accessed and that they “acted immediately to stop the intrusion and conduct a forensic review.”

It was revealed that senior Equifax executives had sold massive amounts of their stock shortly before the announcement of the data breach. Equifax claimed that the executives “had no knowledge that an intrusion had occurred at the time.”
