The breach at Seisint is the second of its kind at a major information provider in recent months. Rival data broker ChoicePoint Inc. announced last month that the personal information of 145,000 Americans may have been compromised in a breach in which thieves posing as small business customers gained access to its database.
In the ChoicePoint scam, at least 750 people were defrauded, authorities say. The case fueled consumer advocates' calls for federal oversight of the loosely regulated data-brokering business, and Capitol Hill hearings on the topic were held last month and are continuing this week.
