Take for example the one hosted on liveolympictickets(dot)com.
Advertised through malicious Facebook posts and likely via other social networking sites and online forums, the site is professionally executed and looks legitimate - especially because it mimics the design and users the colors of the official site of the Olympics.
By clicking on the "Olympic Tickets – Buy Tickets for the London 2012 Olympics" tab, you will be taken to pages where you can supposedly choose the events for which you want to buy tickets for and see details about the offer.
Finally, you will be asked to enter a ton a personal information and to effect the payment by inputing credit card details or choosing between two other payment methods (click on the screenshot to enlarge it):
In the end, you will be presented with a confirmation page that says that the payment will be verified within the next 24 hours and the tickets shipped once it's done.
"We checked the official website of the London Olympics, where it was possible to check if the ticket vendor was legitimate. However, the site was not recognized and therefore unauthorized to sell tickets," Trend Micro warns. "The rest of our investigation shows that it is indeed a phishing page set up to capture user information."
This is just one of these phishing sites - many more domains containing keywords such as "olympics" and "tickets" have recently been set up, so be extra careful out there.
