Arena: It's still there. Cybercrime really overlaps every other program in the FBI. It's not just some 18-year-old kid with no social life trying to hack into the system. It's organized groups, it's state-sponsored organizations, it's terrorist organizations, for whatever purpose, trying to infiltrate our country. It's economic espionage targeting our infrastructure, trying to damage us financially. There's a lot of different reasons and a lot of different groups involved in this. That's why it's such a high priority.

From which areas overseas are most attacks originating right now?

O'Brien: Eastern Europe and Asia are two of the bigger hot spots.

The FBI has reported that some companies have been victimized by another scam, interactive voice response spoofing. How does that work?

Day: Phishers are now spoofing the phone trees of various companies, mainly banks. It sounds exactly like the phone tree that you're used to calling into where you put in your account number and PIN. You're putting in your account number and PIN, but you're actually calling a spoofed number that has been sent to you in an e-mail [saying], "There are problems with your account; we don't want you communicating over the Internet -- it's not safe -- just call this number to check in and make sure your account balance is correct." They're getting [user account and PIN] information by spoofing the phone tree of companies. It's the latest trend.
