"It's a stunning number," Litan said. "This is a quite major ordeal that is presumably going to cost them countless dollars. Controllers and legal advisors are going to have a field day with this one."
Hurray says it has more than 1 billion month to month clients, in spite of the fact that it hasn't uncovered what number of those individuals have email accounts.
