Description
Three spreadsheets containing
5,200 Social Security numbers and other personal details about customers
were inadvertently leaked over an online file-sharing network by a
former employee. Tiversa, a company that monitors P2P networks, found
Excel spreadsheets from the desktop of a financial analyst at ABN
Amro Mortgage Group running LimeWire. Although Tiversa found over
10,000 files, deduplication revealed only 5,208 unique Social Security
numbers, along with names and what type of mortgage each customer
had.
