How to prevent web hacker

Postby guest » Mon Jan 17, 2011 11:16 am

Although we host your website, we are unable to manage security of your content. We have multiple safeguards in place to prevent our servers from being hacked, including prevention against brute force attacks and tight security on user accounts. The actual vulnerabilities a hacker uses to gain access to your home directory or public_html folder are often located in the scripts themselves. For this reason, we provide updates through SimpleScripts as they are made available, and also offer courtesy server backups and a backup utility in cPanel, which you can use to take partial or full snapshots of your account whenever you feel a need.

As to which script was exploited to allow access to your account, we would be uncertain what was used, as most exploits use standard pages in your account with unusually formed requests to inject their own content to your site. There are multiple resources online to help you identify the cause, and we would suggest starting with the authors of the software you are running, to see if there are known exploits or updates that the vendor is aware of.

Here is a security checklist that you can review which can greatly help secure your account sites:
1. Change the Admin Email on your account.
2. Change the Password on your account.
3. Change the Credit Card on file on your account.
4. Update and apply any patches, upgrades, or updates that the 3rd party vendor or web developer of your scripts may have available.
5. Fix any loose file permissions (this may be the most common exploit vulnerability)
6. Delete all non-system Ftp Accounts that were created, or at the very least, change the passwords to the FTP Accounts.
7. Remove any Access Hosts by clicking the "Remote Mysql" icon and clicking the Remove Red X by each entry if there are any entries.
8. Check your scripts for any Header Injection attacks, Sql Injection attacks, Cross-Site Scripting attacks, etc., as well as your php.ini file settings.
9. Check your home/work computers for any viruses, trojans, or keyloggers.

If your scripts are infected, you may want to rollback to the last good snapshot backup of your account. If your backups are also infected, then you may want to consider having us reset your account to start afresh.
