Cyber Monday holiday shoppers beware - scammers can be lurking with bogus websites and fake emails to separate you from your money or even your identity.

While Cyber Monday is the National Retail Federation's official kickoff to the online holiday shopping season, when bargain hunters across the US cash in on one-time deals, deep discounts, and free shipping, in the UK, many retailers also take the opportunity to kick off the Christmas shopping season.

Amazon, Apple, Currys and PC World are among the retailers who have launched price drops over the weekend, following the US's Black Friday and Cyber Monday tradition. 

Today might not be the biggest day for online shopping in the UK though. Argos have said that 29 November last year was their biggest shopping day, while Amazon is predicting 9pm on 5 December as their peak. 

Nevertheless the large number of people expected to shop online Monday presents thieves with a golden opportunity to bilk unsuspecting consumers. If you're planning on letting your fingers do the shopping, here are five tips to help you stay safe.

1. Don't click email links

Following links from phony emails is one of the oldest methods for perpetrating any online scam. So don't be fooled by messages in your inbox offering enticing sales at known sites and then clicking away only to land on a scam site. Instead, open up your Web browser and enter the URL to the site offering the discounts you're looking for and do a search for the items yourself. If you can't find the amazing deal from the email, it's probably a scam, says Ron Meyran, director, security product marketing for security firm Radware.

2. Beware ridiculously deep discounts

With many retailers offering deep discounts, sometimes as much as 50 percent, it may be tough to figure out which deals are too good to be true. The best way not to be taken in by a scam is to only shop at sites you know and trust. You can also check out the Better Business Bureau to see if the site you're visiting is accredited by the group. The National Retail Federation's CyberMonday.com also has a list of legitimate retailers offering Cyber Monday discounts.

3. Secure your purchase

The BBB advises you to make sure your purchase is secure by only entering credit card details on Web pages that use SSL (secure sockets layer) security. To make sure you're on a secure page, check to see that the URL for the page begins with "https://" and not "http://." That "s" lets you know the site is secure. Most browsers will also show a lock icon in the lower right corner of the browser window to let you know you're on a secure site.

4. Pay with credit cards only

Another good tip from the BBB cautions you to only pay for online purchases with a credit card as opposed to a wire transfer or other non-plastic payment method. The law lets you dispute an item on your credit card bill if you don't receive your purchase, according to the BBB. Many credit card providers also have "zero liability" policies meaning you're off the hook if a bad guy gets your credit card and starts using it.

5. Keep your software up-to-date

As with any guide to online security, make sure that you're operating system and anti-virus software are up-to-date with the latest security patches and other updates. That way if you do end up on a malicious site you have the best protection possible against any attempts to download or execute code on your machine. You should also use a modern web browser such as the latest versions of Google Chrome, Internet Explorer, Mozilla Firefox, and Safari. These browsers will also offer protection against malicious activity and steer you away from sites known to exhibit nasty behaviour.

Expectations for a busy Monday are reason enough to take these tips to heart.

The bottom line: Cyber Monday is a great time to take advantage of deals. Just remember to rely on your own common sense and these tips to stay safe and secure.
