First American Financial Corp. FAF, +0.69% shares slipped in the extended session Friday following a report that the title-insurance company’s website leaked hundreds of millions of records containing personal information. First American Financial shares declined 2.2% after hours, following a 0.7% rise to close Friday’s session at $55.26. Late Friday, KrebsonSecurity.com reported that First American exposed about 885 million files, or more than 16 years worth of files. “The digitized records – including bank account numbers and statements, mortgage and tax records, Social Security numbers, wire transaction receipts, and drivers license images – were available without authentication to anyone with a Web browser,” the KrebsonSecurity report said. When contacted by KrebsonSecurity, First American Financial confirmed “a design defect in an application that made possible unauthorized access to customer data” but did not comment on the extent of the exposure or how many records may have been vulnerable, according to the report. First American said it shut down external access to the application when it learned of the flaw. The company said it was evaluating what effect, if any, this had on the security of customer information.
