When I browse on my hosting account, I found the index.php of my website has some code embedded to it, in the beginning there was really long line containing erratic code. There was also two more suspicious files I never saw the content of, I will paste the link of each respected files.
- Code embedded from index.php -- link
- Another php file -- link
- Yet another php file (I had to use file sharing service because the file was big) -- link
I already deleted other files which contain some random suspicious looking code. The website was hosted on shared hosting service, is it a marketing website where I advertise my product.
I also saw that the .htaccess file had been modified to include unwanted .php code, when I change it to my original one-- after a minute or so the file kept reverting back to malicious one.
Can you tell me whats the next step for me ? Should I be concerned at this point ? I will gladly post any information you deemed useful. Thanks !
