#3 Boeing: With all those rocket scientists on staff, it's amazing that Boeing hasn't figured out how to secure its laptops. Boeing had three separate incidents of laptops being stolen along with sensitive employee data. In November 2005, a laptop was stolen with social security numbers and bank account information for 161,000 employees. In April 2006, a laptop with social security numbers for 3,600 employees was stolen from an human resources employee at the airport. In December 2006, a laptop was stolen from an employee's car that had names, addresses, salary information, social security numbers and dates of birth for 382,000 employees. Total employees whose data was put at risk: 546,600.
