It’s common for malware to target e-commerce sites, and these attackers are usually seeking to steal credit card details. In most cases, they will insert scripts that extract data from the checkout forms to siphon fields like the cardholder name, card number and expiration date. Once they have that information, their job is done and they’ll use the data for other nefarious purposes (usually putting it up for sale on the black market). However, every now and then we encounter a case where in addition to that they are also looking to steal details for accounts that customers have created on these sites along with admin account credentials.

Ads are everywhere. They generate revenue for site owners and can present related content to the website being visited.
