I'd like to chime in on this discussion. I work full-time as an IS Director for a beer distributor and have to deal with security issues on a daily basis.
A lot of "phishing" crimes originate from the eastern European area. There are a lot of computer savvy individuals with little money that are desperate to wring out as much money via fraud as possible. Since they are in another country, it is next to impossible to try and recoup losses by going after them. Your best protection is prevention (ounce of prevention worth a pound ... blah blah ).
There are several major ways that hackers / phishers will gather information about you. These range from easy to extremely difficult. There are also "localized" methods and "global" methods. I'll touch on a few and answer any questions anyone might have.
The easiest way to gather information is through "phishing." Phishing is the process of sending an illegitimate e-mail that appears to come from a trusted source asking for account information or clarification. It can get technical, but the end result might be an e-mail in your inbox from "E*Trade" warning of suspicious activity.
You read the e-mail and naturally are concerned, so you click the link and go to a page that looks official enough -- it looks and feels just like you are at their site. Next, they inform you that you should reset your password -- but first log in with your current username and password. **** HOLD UP ***** What just occurred here? You just gave them exactly what they need to hijack your account.
Phishing is by far the most prevalent way that they (the hackers) obtain sensitive information.
Phishing is a high-treat "global" threat. It is global in the sense that anyone from anywhere in the world can initiate this.
Trojans and viruses are also problematic. I would place these as a medium-high threat. It would be incredibly easy for me to program a simple key-logger that records everything you type on your keyboard and transmit that information via E-mail or an IRC channel where a "bot" could collect the information. Trojans and viruses don't just slip into your computer -- you generally have to make an active choice to disregard security to find one on your computer. Internet Explorer can also be a large security risk. ***** YOU MUST APPLY SECURITY PATCHES ASAP *****
1. Go to
http://windowsupdate.microsoft.com and install all the security updates for your OS and Internet Browser (assuming you are running Windows). Reboot. Do it again. Keep doing this until the site tells you there are no more updates available.
2. Download ADAWARE and scan your system for any adware or spyware trojans. Last I checked, this program was owned by Lavasoft so make sure you download the legit version.
3. Run a free online virus-scan at this site:

I can go into many other security related matters if anyone has questions.
My personal feelings toward WiFi hotspots is this -- try not to conduct sensitive transactions on an unsecured Wifi connection. 128 bit WEP encryption is crackable, but it requires time and a statistically usable amount of packets sniffed before the security is breached. I seriously doubt that anyone is cracking WEP connections at their local Starbucks.
If anyone has questions, ask away -- I operate an e-mail server for three distribution points and see around 100-200 incoming illegitimate phishing scams every day. Every time a new one comes out, they get a tad bit sneakier as well.
Scary stuff.
