Sunnyvale, Calif.-based security company Proofpoint reported the discovery of a massive phishing exploit aimed at customers of JPMorgan Chase and a few other money center banks.

In an interview with CU Times, Proofpoint Vice President Kevin Epstein declined to name the other institutions, but indicated they were top 10 banks.

Especially interesting about this phish was that it departed from the recent trend where phishes – emails that aim to con the gullible into surrendering their financial login credentials to a criminal masquerading as a financial institution – had become more polished and well crafted, in part to better foil security screens that had been erected by email gateways.
