If you have been the victim of a hacker, don’t worry—it is possible to recover. This article will help give you information about infiltration, and a few steps to help you recover.
There are two common ways account are infiltrated:
1) The attacker successfully authenticated and accessed your account like a regular user. The attacker already knew your password (e.g., because your home computer has a virus or other program logging your keystrokes) or was able to guess your password (e.g., using a brute force or dictionary attack).
2) The attacker exploited a security vulnerability in a script or application installed on your account. This is most likely the case if you are running old or outdated software that has known security vulnerabilities (e.g., Joomla 1.0). This type of vulnerability can also occur in the database through a MySQL injection, as such your database integrity is also most likely compromised.
To help mitigate future attacks, we strongly recommend that you perform all of the following:
– Before doing anything else, run a complete system scan for viruses and malware. Ensure that your computer is running up-to-date anti-virus and anti-malware software. If you don’t have security software or are dissatisfied with your current security program, try downloading the free, non-obtrusive Microsoft Security Essentials from http://www.microsoft.com/security_essentials/
– Login to your cPanel and change your main cPanel password. Also change the passwords for all of your e-mail, FTP users, and MySQL users. Make sure the new passwords are secure; they should contain a mix of upper- and lowercase letters and numbers. For extra security, also add symbols or punctuation characters to your passwords.

– Change the passwords for any administration-type areas of your web site (e.g., WordPress control panel, shopping cart administration).
– Visit cPanel and install any updates that are available to your installed applications. Periodically check Fantastico/Softaculous/Installatron for updates to software and install these updates as soon as they become available. Updated versions often contain important security patches.
– Check for newer versions of scripts and applications that you’ve manually installed on your account. cPanel does not keep track of custom applications, so you need to periodically check the developers’ website and make sure you install important security updates for all of your manually-installed scripts.
– Adjust the security settings for PHP in your php.ini file. The options for “allow_url_fopen”, “allow_url_include”, and “register_globals” should be set to “off” if at all possible.
– Search the Internet for further ways to secure your specific web applications. There are usually quite a few extra steps that can be taken specific to each application.
– Make frequent backups of your account files and your databases. Also keep an eye on the files within your account in general. Pay attention to files that aren’t yours or recently modified files, for example. This will help ensure that your backups are usable and not infected with malicious code.
Lastly, if web browsers are giving warning message because Google is currently classifying your web site as dangerous, you’ll want to create a free Google Webmaster Tools account at http://www.google.com/webmasters/. Once you have logged into your Google Webmaster Tools account and added your web site, you will be able to click on a link to request a review of your site. Google will visit your site again and verify that the malicious code has been removed, then remove the “This site may harm your computer” warnings.
