Today is the busiest day of the year for online shopping, known as “Cyber Monday.” More than 70% of online retailers are planning special promotions this year compared to 42.7% two years ago.

More than ever, there are several new threats you need to be aware of if you plan on shopping during cyber Monday:

Clickjacking – This holiday season, many will fall victim to this attack — by clicking on a phony e-card, Christmas videos, Facebook ‘Like’ chain messages and online coupons that has a malicious program or link is hidden behind it

Drive-By Attacks – This type of attack most commonly occurs with a pop-up ad on a website – when you click on it to make it go away it secretly infects your computer. This can also infect a smartphone when surfing the Web.

“Man-in-the-Browser” – Another Internet browser scam that attacks a flaw or un-patched vulnerability. The best way to avoid a MITB attack is to keep your antivirus up to date and use common sense when surfing the Web.

And just one more tip: The work hour of 1pm today is the peak time for Cyber Monday online shopping, so many sites may run slower than normal during this time.
