Hopefully, the tapes were misplaced rather than stolen for the purposes of identity theft or fraud.

QUOTE: May 30, 2008 (Computerworld) Bank of New York Mellon Corp. officials last week confirmed that a box of unencrypted data storage tapes holding personal information of more than 4.5 million individuals was lost more than three months ago by a third-party vendor during transport to an off-site facility.

The bank informed the Connecticut State Attorney General's Office that the tapes belonging to its BNY Mellon Shareowner Services division were lost in transport by off-site storage firm Archive America on Feb. 27. The missing backup tapes include names, birth dates, Social Security numbers, and other information from customers of BNY Mellon and the People's United Bank in Bridgeport, Conn., according to a statement by Connecticut Attorney General Richard Blumenthal.
