Script kiddie code #1
Description
These lines of code prevent any sensible development and review of the webshell's code. They are immediately obvious to anyone who is reviewing the files (like a normal webshell would be, just in a different way). I suggest you replace this with the base64 decoded and gunzipped piece of code (also removing the dependency on gzinflate PHP option) which will allow for easier modification of the webshell code.
