States Seek More Info from JPMorgan Chase on Breach

States probing last summer's massive hack at JPMorgan Chase & Co have asked for detailed data on the company's security practices and want to know whether the bank is certain that no sensitive account data was stolen. "Critical facts about the intrusion remain unclear, including details concerning the cause of the breach and the nature of any procedures adopted or contemplated to prevent further breaches," more than a dozen states said in a letter sent to the bank.
