Identity theft is not just about high tech crimes like phishing, malware and skimming. It is also about dumpster diving (looking in your trash) and old-fashioned theft (wallets). With a discarded bank statement thieves can change your billing address and phone number to their own. There are many other "cons" to which you should be alert. For example, you can be "phished" by mail if you receive a letter that looks like it's from your bank warning of identity risks and asks you to call the number provided. In this case, you'll be calling the thief's number! The scams are constantly changing, to take advantage of current events, like a bad economy.
For more information, you can visit the UK's Fraud Prevention Service, CIFAS, or the Anti-Phishing Working Group (APWG). See, How can I prevent identity theft?
