HSBC Bank and American Express customers were among the victims, according to criminal complaint.
The suspects allegedly either used the personal information to open new accounts with banks or hijacked existing accounts by submitting change of address forms via the Internet.
Authorities say an unidentified co-conspirator aided them, providing an electronic spreadsheet including names, addresses, telephone numbers, and credit card numbers with expiration dates and three digit security codes for 10,000 individuals.
