Back in April, a group of hackers reportedly stole over 2.9 billion records from a background check company called National Public Data.

“The information that was suspected of being breached contained name, email address, phone number, Social Security number, and mailing address(es),” NPD said. “We cooperated with law enforcement and governmental investigators and conducted a review of the potentially affected records and will try to notify you if there are further significant developments applicable to you.” (The NPD site is now closed, due to this incident.)
