Possible Website Security Hack?
Below injected stylesheet is seen on an SSL protected page:
The background: url(http://i.imgur.com/WLonK99.png) no-repeat;
contains a ref to a non SSL image causing a new tab to open.
The image is on a div element that wraps around an iFrame whose src is a form hosted on a Credit Card Payment Gateway.
The style appears to be injected from jquery 1.9.1
I cannot find the offending script in any file in the site folders.
Here is a screenshot of the issue in Chrome: http://snag.gy/9AGN2.jpg
