Leading fintech company Fiserv processes transactions for hundreds of financial institutions. So when an investigation by Brian Krebs revealed security vulnerabilities in its software, one credit union took notice—and is taking action.

KrebsOnSecurity reports:

A Pennsylvania credit union is suing financial industry technology giant Fiserv, alleging that “baffling” security vulnerabilities in the company’s software are “wreaking havoc” on its customers. The credit union said the investigation that fueled the lawsuit was prompted by a 2018 KrebsOnSecurity report about glaring security weaknesses in a Fiserv platform that exposed personal and financial details of customers across hundreds of bank Web sites.

Brookfield, Wisc.-based Fiserv is a Fortune 500 company with 24,000 employees and $5.8 billion in earnings last year. Its account and transaction processing systems power the Web sites for hundreds of financial institutions—mostly small community banks and credit unions.

In August 2018, in response to inquiries by KrebsOnSecurity, Fiserv fixed a pervasive security and privacy hole in its online banking platform. The authentication weakness allowed bank customers to view account data for other customers, including account number, balance, phone numbers and email addresses.
