Banking industry giant NCR Corp. [NYSE: NCR] late last month took the unusual step of temporarily blocking third-party financial data aggregators Mint and QuicBooks Online from accessing Digital Insight, an online banking platform used by hundreds of financial institutions. That ban, which came in response to a series of bank account takeovers in which cybercriminals used aggregation sites to surveil and drain consumer accounts, has since been rescinded. But the incident raises fresh questions about the proper role of digital banking platforms in fighting password abuse.
If you bank online and choose weak or re-used passwords, there’s a decent chance your account could be pilfered by cyberthieves — even if your bank offers multi-factor authentication as part of its login process. This story is about how crooks increasingly are abusing third-party financial aggregation services like Mint, Plaid, Yodlee, YNAB and others to surveil and drain consumer accounts online.
