Sudden image injection using YUI mesh

Question

I tried to use the YUI grid, and I noticed something strange on my web page:

<img id="fvdkoff-target-image" style="border: medium none ; margin: 0px; position: relative; visibility: visible; color: transparent; z-index: 2147483647; left: 424px; top: 274px;" src="data:image/png;base64,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"/> 

I was wondering if anyone ran into this problem?

the above type of injection in the form of an unusual image changes my site design.

Can anyone help?

By the way, the strange code you entered does not appear in the source code. however, if you try to debug a page using FireBug and click on the space below the footer, the entered code will be clearly displayed on it.

it's better.

Answer 1

When I check the page with Firebug, I do not get the image. I see empty space. Its there because reset -fonts-grid.css sets the background of the html element to white.

If you select the html element in Firebug and cancel the background rule in the style inspector, your background will behave as expected.

As for the image, I don’t know what it is, why you see it, but I don’t, or where it came from, but Google’s search queries on the “fvdkf image” show that it appears everywhere.

As an alert, this post has been for 40 minutes and its result is Google 4.

Answer 2

I guess it might be some kind of injection script, but the 'src' attribute is a coded string that displays as a .png file - like a little bubble icon. try copying the value and pasting it into the address bar of your browser to view it. Does it help?
