网站给机器发重复内容重复注册己经不是什么希事了，我们只要有注册页面或者是评论页面就会有这种问题出现了，下面我找了两个例子大家一起看看。
网站开放注册的时候有一些渣渣就喜欢乱搞我们的网站。使我们站长们 都是蛋疼无比。所以就去百度找了找防止恶意注册。一般都是加验证码。但是会网页的人一般都是在你的要提交的那个页面利用url传参数。在写入数据的文件没有写好 就很容易被利用了! 所以我得出了2个解决方法
例子、
1.在提交的时候获取客户端IP 在IP第二次访问或者第三次提交数据的时候视为恶意提交
2.使用session访问2次或者3次 视为恶意注册
以下是代码:
| 代码如下 |
复制代码 |
|
<?php
$cs = $_SESSION['cs'] = $_SESSION['cs']+1;//每访问一次加1
$sql = "INSERT INTO ".$DB_PREFIX."user (username,password,nickname,role,photo,email,description) VALUES ('$username','$password','$user_namex','writer','','$name_mailbox','')";
if($cs < "2"){//页面被反复刷新的时候 不执行代码
if( mysql_query($sql) == 1){?>
<script language="javascript" type="text/javascript">

当然这个办法也不是很好的。但是目前就感觉这个比较好了
例子、
比较高级的办法RSA算法进行加密通讯 .
avascript部分代码（with jQuery）
| 代码如下 |
复制代码 |

$(document).ready(function(){
//十六进制公钥
var rsa_n = "C34E069415AC02FC4EA5F45779B7568506713E9210789D527BB89EE462662A1D0E94285E1A764F111D553ADD7C65673161E69298A8BE2212DF8016787E2F4859CD599516880D79EE5130FC5F8B7F69476938557CD3B8A79A612F1DDACCADAA5B6953ECC4716091E7C5E9F045B28004D33548EC89ED5C6B2C64D6C3697C5B9DD3";
$("#submit").click(function(){
setMaxDigits(131); //131 => n的十六进制位数/2+3
var key = new RSAKeyPair("10001", '', rsa_n); //10001 => e的十六进制
var password = $("#password").val();
password = encryptedString(key, password); //不支持汉字
$("#password").val(password);
$("#login").submit();
alert(password); //test
});
});

其中密钥的获取是关键（其他难点已经被从代码中解决）
关于AES加密的算法我们就不说了，这里主要给各位演示了三个关于AES算法实现的加密例子，希望本文章能给你带来帮助。
话不多说，先放上代码，一共有两个文件：AES.php（aes算法类文件）和aesDemo.php（应用实例文件），这里只贴出aesDemo.php，其他的看附件吧！
aesDemo.php：
例子，
| 代码如下 |
复制代码 |
|
<?php
require_once('./AES.php');
//$aes = new AES();
$aes = new AES(true);// 把加密后的字符串按十六进制进行存储
//$aes = new AES(true,true);// 带有调试信息且加密字符串按十六进制存储
$key = "this is a 32 byte key";// 密钥
$keys = $aes->makeKey($key);
$encode = "123456";// 被加密的字符串
$ct = $aes->encryptString($encode, $keys);
echo "encode = ".$ct."<br>";
$cpt = $aes->decryptString($ct, $keys);
echo "decode = ".$cpt;
?>
|
例子、AES加密类
| 代码如下 |
复制代码 |
|
<?php
//php aes加密类
class AESMcrypt {
public $iv = null;
public $key = null;
public $bit = 128;
private $cipher;
public function __construct($bit, $key, $iv, $mode) {
if(empty($bit) || empty($key) || empty($iv) || empty($mode))
return NULL;
$this->bit = $bit;
$this->key = $key;
$this->iv = $iv;
$this->mode = $mode;
switch($this->bit) {
case 192:$this->cipher = MCRYPT_RIJNDAEL_192; break;
case 256:$this->cipher = MCRYPT_RIJNDAEL_256; break;
default: $this->cipher = MCRYPT_RIJNDAEL_128;
} // www.111cn.net
switch($this->mode) {
case 'ecb':$this->mode = MCRYPT_MODE_ECB; break;
case 'cfb':$this->mode = MCRYPT_MODE_CFB; break;
case 'ofb':$this->mode = MCRYPT_MODE_OFB; break;
case 'nofb':$this->mode = MCRYPT_MODE_NOFB; break;
default: $this->mode = MCRYPT_MODE_CBC;
}
}
public function encrypt($data) {
$data = base64_encode(mcrypt_encrypt( $this->cipher, $this->key, $data, $this->mode, $this->iv));
return $data;
}
public function decrypt($data) {
$data = mcrypt_decrypt( $this->cipher, $this->key, base64_decode($data), $this->mode, $this->iv);
$data = rtrim(rtrim($data), ".. ");
return $data;
}
}
//使用方法
$aes = new AESMcrypt($bit = 128, $key = 'abcdef1234567890', $iv = '0987654321fedcba', $mode = 'cbc');
$c = $aes->encrypt('haowei.me');
var_dump($aes->decrypt($c));

PHP木马其实就是利用php程序写的一个php文件他可以对文件进行任何的读写操作，同时可以上传下载数据库等等，说得好听点就是一个完美的网站文件管理系统了，下面小编总结了一些常见的PHP木马攻击的方法防御技巧.
1、防止跳出web目录
首先修改httpd.conf，如果你只允许你的php脚本程序在web目录里操作，还可以修改httpd.conf文件限制php的操作路径。比如你的web目录是/usr/local/apache/htdocs，那么在httpd.conf里加上这么几行：
php_admin_value open_basedir /usr/local/apache
/htdocs
这样，如果脚本要读取/usr/local/apache/htdocs以外的文件将不会被允许，如果错误显示打开的话会提示这样的错误：
Warning: open_basedir restriction in effect. File is in wrong directory in
/usr/local/apache/htdocs/open.php on line 4
等等。
2、防止php木马执行webshell
打开safe_mode，
在，php.ini中设置
disable_functions= passthru，exec，shell_exec，system
二者选一即可，也可都选
3、防止php木马读写文件目录
在php.ini中的
disable_functions= passthru，exec，shell_exec，system
后面加上php处理文件的函数
主要有
fopen，mkdir，rmdir，chmod，unlink，dir
fopen，fread，fclose，fwrite，file_exists
closedir，is_dir，readdir.opendir
fileperms.copy，unlink，delfile
即成为
disable_functions= passthru，exec，shell_exec，system，fopen，mkdir，rmdir，chmod，unlink，dir
，fopen，fread，fclose，fwrite，file_exists
，closedir，is_dir，readdir.opendir
，fileperms.copy，unlink，delfile
ok，大功告成，php木马拿我们没辙了，遗憾的是这样的话，利用文本数据库的那些东西就都不能用了。
如果是在windos平台下搭建的apache我们还需要注意一点，apache默认运行是system权限，这很恐怖，这让人感觉很不爽.那我们就给apache降降权限吧。
net user apache fuckmicrosoft /add
net localgroup users apache /del
ok.我们建立了一个不属于任何组的用户apche。
我们打开计算机管理器，选服务，点apache服务的属性，我们选择log on，选择this account，我们填入上面所建立的账户和密码，重启apache服务，ok，apache运行在低权限下了。
实际上我们还可以通过设置各个文件夹的权限，来让apache用户只能执行我们想让它能干的事情，给每一个目录建立一个单独能读写的用户。这也是当前很多虚拟主机提供商的流行配置方法哦，不过这种方法用于防止这里就显的有点大材小用了。
一聚教程小编提醒您：如果你对这些配置不明白我们可以使用安全狗或卖咖啡来设置网站目录不可写php文件，这样就是有bug也无法上传php文件了，同时限制一些提取操作在这里我就不介绍了大家要在本站找一些相关教程。
正则表达式注入攻击你sql数据库本人是第一次听过了，下面我总结了一些常见的sql攻击正则表达式同时在文章最后也举了一个实例与大家一起分析攻击原理。
我们都已经知道，在MYSQL 5+中 information_schema库中存储了所有的 库名，表明以及字段名信息。故攻击方式如下：
1. 判断第一个表名的第一个字符是否是a-z中的字符,其中blind_sqli是假设已知的库名。
注：正则表达式中 ^[a-z] 表示字符串中开始字符是在 a-z范围内
| 代码如下 |
复制代码 |
|
index.php?id=1 and 1=(SELECT 1 FROM information_schema.tables WHERE TABLE_SCHEMA="blind_sqli" AND table_name REGEXP '^[a-z]' LIMIT 0,1) /*
|
2. 判断第一个字符是否是a-n中的字符
| 代码如下 |
复制代码 |
|
index.php?id=1 and 1=(SELECT 1 FROM information_schema.tables WHERE TABLE_SCHEMA="blind_sqli" AND table_name REGEXP '^[a-n]' LIMIT 0,1)/*
|
3. 确定该字符为n
| 代码如下 |
复制代码 |
|
index.php?id=1 and 1=(SELECT 1 FROM information_schema.tables WHERE TABLE_SCHEMA="blind_sqli" AND table_name REGEXP '^n' LIMIT 0,1) /* www.111cn.net
|
4. 表达式的更换如下
| 代码如下 |
复制代码 |
|
expression like this: '^n[a-z]' -> '^ne[a-z]' -> '^new[a-z]' -> '^news[a-z]' -> FALSE
|
这时说明表名为news ，要验证是否是该表明 正则表达式为'^news$'，但是没这必要 直接判断 table_name = ’news‘ 不就行了。
5.接下来猜解其它表了 只需要修改 limit 1,1 -> limit 2,1就可以对接下来的表进行盲注了。
例
| 代码如下 |
复制代码 |
|
$Exec_Commond = "( \s|\S)*(exec(\s|\+)+(s|x)p\w+)(\s|\S)*";
$Simple_XSS = "( \s|\S)*((%3C)|<)((%2F)|/)*[a-z0-9%]+((%3E)|>)(\s|\S)*";
$Eval_XSS = "( \s|\S)*((%65)|e)(\s)*((%76)|v)(\s)*((%61)|a)(\s)*((%6C)|l)(\s|\S)*";
$Image_XSS = "( \s|\S)*((%3C)|<)((%69)|i|I|(%49))((%6D)|m|M|(%4D))((%67)|g|G|(%47))[^\n]+((%3E)|>)(\s|\S)*" ;
$Script_XSS = "( \s|\S)*((%73)|s)(\s)*((%63)|c)(\s)*((%72)|r)(\s)*((%69)|i)(\s)*((%70)|p)(\s)*((%74)|t)(\s|\S)*";
$SQL_Injection = "( \s|\S)*((%27)|(')|(%3D)|(=)|(/)|(%2F)|(")|((%22)|(-|%2D){2})|(%23)|(%3B)|(;))+(\s|\S)*";

sql
分析
如果使用这个函数的话，这个函数会绕开PHP的标准出错处理，所以说得自己定义报错处理程序(die())。
其次，如果代码执行前就发生了错误，那个时候用户自定义的程序还没有执行，所以就不会用到用户自己写的报错处理程序。
那么，PHP里有一套错误处理机制，可以使用set_error_handler()接管PHP错误处理，也可以使用trigger_error()函数主动抛出一个错误。
set_error_handler()函数设置用户自定义的错误处理函数。函数用于创建运行期间的用户自己的错误处理方法。它需要先创建一个错误处理函数，然后设置错误级别。
关于的用法：
| 代码如下 |
复制代码 |
|
function customError($errno, $errstr, $errfile, $errline)
{
echo "<b>错误代码:</b> ［${errno}］ ${errstr}＼r＼n";
echo " 错误所在的代码行： {$errline} 文件{$errfile}＼r＼n";
9 echo " PHP版本 ",PHP_VERSION, "(" , PHP_OS, ")＼r＼n";
// die();
}
set_error_handler("customError",E_ALL| E_STRICT);
|
总结
PHP遇到错误时，就会给出出错脚本的位置、行数和原因，有很多人说，这并没有什么大不了。但泄露了实际路径的后果是不堪设想的，对于某些入侵者，这个信息可是非常重要，而事实上现在有很多的服务器都存在这个问题。 有些网管干脆把PHP配置文件中的 display_errors 设置为 Off 来解决，但本人认为这个方法过于消极。有些时候，我们的确需要PHP返回错误的信息以便调试。而且在出错时也可能需要给用户一个交待，甚至导航到另一页面。但是有了set_error_handler()之后，这些矛盾也都可以解决掉了。
但是发现很少用这个函数。
