Make sure that the URL is accurate, and check the web site certificate to make sure that you are visiting an authentic eBay web page. Description eBay allows users to incorporate a type of code, also known as scripting, into the auction descriptions on its web site. An attacker can use this code to modify pages on eBay's web site or redirect you to a malicious web page. These may appear to be legitimate eBay web pages that request personal information. Using these techniques, an attacker may be able to collect your passwords, credit card numbers, or other personal information.
