Hard to believe we’ve been around to post this yet a third time, but here you go. Our list of advice for shopping safely online this year; and we even updated it this time:

Yes folks, Black Friday is only days away and the silly season is upon us. As someone born and bred in good old North Jersey (until I could legally escape), land of honey and shopping malls, this is a time so deeply ingrained into my subconscious that I’ve occasionally found myself sleepwalking around the nearest parking lot, looking for our old wood-paneled station wagon.

These days, thanks to the wonder of the Internet, anyone can experience the hustle and bustle of the Paramus malls from the comfort of their own home. And to help keep your shopping experience authentic, there’s no shortage of cheats and thieves ready to yank your painstakingly chosen gifts right out of the virtual trunk of your web browser. Of course they might take your house with them, which, even in Jersey (despite the legends) is somewhat rare.

In the spirit of safe and happy holidays, Securosis presents our top 6 tips for safe online shopping, simply presented for the technical or non-technical consumer. Some of these tips also apply to the real world for those of you who just can’t restrain the draw to the mall. Spread the fun, and feel free to post your own tips in the comments.

Use a dedicated credit card, temporary credit card number, or PayPal account for holiday shopping. Our first tip is also useful for the physical world- still the origin of most credit card fraud. Take your card with the lowest limit and use it exclusively for holiday shopping. Use one you can monitor online, and check the activity daily through the holidays (weekly at a minimum). Make sure it isn’t a debit card, and turn off any automatic payments (so you can dispute any charges before making payments). Keep tracking activity at least weekly for 12 months after the holidays are over, or cancel the card. DON”T USE A DEBIT CARD!!! These don’t have the same protections as credit cards, and you’re responsible for fraudulent charges. As for temporary credit cards or PayPal, read on to our second tip.
Only use credit cards at major online retailers; use a PayPal debit account or temporary credit card for smaller shops . Sure, you might get a better deal from Billy-Bobs-Bait-Shop-And-Diamond-Wholesaler.com, but many smaller retailers don’t follow appropriate security practices. Those hosted with a major service are often okay, but few consumers really want to check the pedigree for specialty shops. Instead, create a dedicated PayPal account that’s not linked to any of your bank accounts or credit cards. Credit it with as much cash as you think you need and use it for those riskier online payments. Worst case, you only lose what’s in that account, and you can easily cancel it anytime. Another option, depending on your credit card company, is a temporary credit card number for online shopping. These are single use, or single retailer/session numbers that can’t be used again or leveraged to run up your account. Charges still appear on your same bill and are tied to your main credit card account. Check with your credit card company to see if they offer this service, but most of the major card issuers have it as an option. I like these better than account passwords (e.g. Verified by Visa and Mastercard SecureCode) since they work everywhere, and you don’t have to worry about anyone sniffing them.
Never, ever, ever ,ever click on ANYTHING in email. It doesn’t matter if your best friend sent you a really good deal in email. It doesn’t matter if it’s your favorite retailer and you’ve always gotten email offers from them. Repeat after me, “I will never click on anything in email.” No special offers. No Ebay member to member emails. No “fraud alerts” to check your account. No nothing. Ever. Nada. Attackers are getting more and more refined in their attacks, some of which are very hard to distinguish from legitimate emails. Spam waves over the holidays are expected to break records this year. When you see an interesting offer in email, and it’s a business you want to deal with, just open your web browser, type in the address manually, and browse to the item, offer, or account area. Email is the single biggest source of online fraud; never click on anything in email!
Update your browser- use Firefox 3.1, IE 7 or 8, Safari 3.2.1, or Opera 9.6. Turn on the highest security settings. Over the past few months or so we’ve seen big updates of all the major browsers to include enhanced security features. Since the Safari update last week, all major browsers include features to help detect fraudulent sites- if you see a warning, shut down the browser and don’t go back to that site. All of these browsers will ask you before installing any software when you visit a site; when shopping, never allow the site to install anything. Either it’s a fraud or they don’t deserve your business. Pay particular attention to plugins to watch video, or free games unless you know it’s a trusted site (both are usually trojans). Most browsers now install with security enabled by default, so we won’t be providing detailed instructions here. Just download them. Now. Then come back and read the rest of this list. We’ll wait.
Download and install NoScript for Firefox. This is a free plugin for Firefox that blocks anything from running in your browser that you don’t allow (like Javascript, Flash, and so on). You won’t need it if you just stick with Amazon, but if you use Google to help you find that can’t-miss Drink-With-Me Elmo, you shouldn’t be trolling the Internet without it. If you don’t want it bothering you all the time, at least use it during your holiday shopping and turn it off later.
Keep your antivirus, firewall, antispam, and anti-spyware up to date. I don’t really care which product you use (and truth be told, we don’t really like most of the commercial ones, and don’t use them on our Macs) but as bad as some of these perform they really are essential on a PC. All users, regardless of platform, should use an email service that includes antivirus and antiphishing. For Windows users, Windows Defender is a good, free additional tool to limit spyware. Right now there’s no known spyware for Macs, unless you’re stupid and start manually downloading things.

These six simple steps won’t stop all fraud, but will significantly reduce both the chances you’ll be a victim, and the damage if you are. Feel free to email them to your friends and family who won’t normally browse a security site like this one.
