I'll see your Epsilon mail addresses and raise you 3 1/2 million Texans' personal records.
While the Epsilon leak got an excessive amount of media attention, given its limited potential for phishing (let alone spear phishing), it seems bizarre that there hasn't been much more attention paid to the exposure of all those employment/retirement records exposed for, reportedly, nearly a year.

Well, I guess that depends partly on whether the media start to take more of an interest.
