Identity thieves obtain personal and financial information in many ways, such as stealing wallets or data from homes, in order to access credit cards and bank accounts without permission. They then use the stolen information to make purchases or sell the data online, with some identity theft rings generating over $5 million through stolen credit cards. To reduce risk, people should guard their social security number, use passwords, minimize carried information, monitor statements, secure mail, check credit reports, and use firewalls on devices.
