b. “edoced_46esab…”

c. “getMama…”

d. “115,99,114,105,112,116….”

e. “document.write(‘<iframe…..”

5. Look for any php files in any image, css, upload, download, etc directories that would not normally have a php file in them. Check the document substance for base64 strings and which points to it being a php shell, for example, "FilesMan", "c999sh". If you find any file matches with this, Then DELETE THEM.

6. Change your cPanel and FTP passwords.
