Re: Hacked Site/Virus

Your first steps would be to revert any changed core files. Remove unrelated code files. Then apply the shoplift patch that was issued several months ago.

Re: Hacked Site/Virus

I agree with the technical recommendations offered by earlier submitted answers, but I recently answered a couple of similar or at least related questions on the Magento Stack Exchange and thought I would follow up with some of the additional insights from a few more recent remediation efforts.

A security incident like this one is a challenge that must be addressed with responses from both the technical and business perspectives and given that the business implications include potential regulatory and contractual requirements that specifically impact the technical actions you may be required to perform, I thought I would outline them together in this answer.

 

Before performing any of the earlier recommended technical activities, review the following and determine which, if any, are allowed given the regulations you are subject to in your location and the contracts you have entered into with your issuing banks, gateway providers and processing service partners.

 

  1. You should first take some time to review the Official Magento Security Best Practices Guide. It contains a wealth of information to help you deal with a compromised installation as well as how to prevent it from happening in the future.

    It's based on the work of the Magento Security Team as well as knowledge shared by several Magento Security Experts both on Magento Stack Exchange and here in the Magento Community Forums.

  2. If this site generates any real volume of transactions, you should probably not attempt to resolve the issue completely on your own. Contact a Magento Security Expert who is familiar with all of the following:

    1) The specific Magento version you are running

    2) The laws covering Data Breaches, Privacy Protections, and Customer Notification Requirements that govern Merchants operating in and/or located in your geographical region.

    3) Reviewing contracts and business partner agreements with your Merchant's Gateway Provider, Processing Services, and Credit Card Companies

Depending on your location, you may be subject to local, regional, and / or national laws that require you to either perform very specific actions in response to a security event or to engage the assistance of someone (or a company) that is specifically licensed as a forensic information security specialist.

In addition, the fine print of the credit card processing agreements signed with the store's Credit Card Merchant Gateway, Financial Institution, Issuing Bank, and the Credit Companies themselves may require other specific actions be performed and that law enforcement be engaged or the store may be held responsible for any charges incurred by the attacker(s).

Finally, again, depending on your location, your store may be required by law to notify the customers of the data breach in very specific ways and the Nation / States in which your customers reside may impose additional requirements on notifying affected customers. Failure to comply with these requirements might make the store subject liable for fines and penalties outside of any costs imposed by your processing company or gateway provider.

These laws & contractual requirements vary greatly across different geographical regions and also across different financial institution and businesses that offer clearing and gateway services to merchants so it is important to engage the services of someone who is both a Magento Security Expert and also familiar with the laws specific to your geographic location and who can assist you with both the technical effort in remediating your hacked site as well as the business activities required by any contracts that have been entered into by the Merchant.

Once you have identified a suitably experienced partner to assist you in your remediation effort, ask them to confirm the next technical steps to take, including actions such as imaging the compromised system, contacting law enforcement, disconnecting the system from the network and investigating the affected systems.

REMEMBER: You are no longer in possession of JUST a hacked system! Your compromised Magento installation is now also an ACTIVE crime scene, and in many jurisdictions, the crime is a severe one. In the US, it's almost universally a felony (severe crime) with specific prohibitions against tampering with evidence left behind by the perpetuators of the criminal act without proper supervision of licensed personnel and/or law enforcement professionals.

It would be unwise to bring the system back to a working state only to find out that you YOURSELF had just committed a crime punishable by fine and/or jail time. Standard Disclaimer: I am not a lawyer and this does not constitute legal advice.

Note: Most of the links above point to resources specifically written for US Merchants, but they all also contain links for merchants in other regions as well as contact information to engage the specific security support teams to assist you in your own location.
