my final $job, from which I retired a few years ago (when my department was shut down after 20 years), was a large multinational manufacturing firm.
some years earlier the HR and Payroll operations, which had been moved overseas to a SE asian country, someone got ahold of a jr HR person by phone, and faked being a US executive VP on the road, and convinced the jr HR person to email them the entire US payroll database. that included name, SS#, home and work address, phone numbers, bank routing numbers for autodeposit, spouse and children names, and their SS #s, etc etc etc. this effected something like 15000 US employees.
who needs computer hacking when you've got a telephone?
