Discover Financial Services reports three data breaches to California AG

For the second time this year, Discover Financial Services reported a set of data breaches on the same day to the California Attorney General's Office.

The latest breaches occurred on Oct. 27, 2015, Oct. 25, 2015, and on June 21, 2015, respectively, and were all reported Sept. 23, 2016, according to their respective breach notifications.

It is unclear how many people were affected and the company said it's difficult to know exactly what information was compromised but did say breaches did not involve Discover card systems and that those who were affected will receive new cards, the notification said.

The two earlier breaches occurred on Feb. 19, 2014, and Aug. 2, 2015, and were reported to the California AG's office in March 2016. Limited details were also provided for these breaches as well.
