A large number of websites are being hacked due to possible outdated scripts installed at the backoffice (website-admin-panel).
This type of vulnerability can occur due to any of the followings.
1. Vulnerability in website’s database through SQL injection
2. Injecting client-side scripts into web pages as Cross-Site Scripting (XSS)
3. Uploading of malicious piece of code through Backdoor Shell to exploit the website contents
Simply restoring the backup (If you already have maintained the offline website backup) or removing vulnerable files is just a quick alternative that does not guarantee website sustainability.
If your website was developed through Xperts then you better need to consider upgrading your PHP scripts through loading up the new Backoffice (website-admin-panel), so that we can deliver you the maximum security. If we did not designed or developed your website then we strongly advise you to either speak with your website developer/programmer to upgrade your PHP scripts to stop SQL injection, Cross-Site Scripting (XSS) and Backdoor Shell or you can ask us to arrange a meeting in your office to discuss available solutions from Computer Xperts.
If you wish to arrange a meeting to discuss possible solutions in details then please write back to firstname.lastname@example.org
