In his talk, “Writing Viruses for Fun, Not Profit,”Ben Dechrai (after making the viewer take a pledge to only use this knowledge for good and not evil) walks through how many viruses operate, and just how easy it is to build your own self-replicating virus in PHP.

The danger of many of these viruses according to Ben is that the most dangerous viruses often escape detection by not looking like a virus. Instead they encrypt their code to hide their true intent, while also constantly adapting and evolving.

Perhaps even more dangerously, they act like they’re benign and don’t actually do anything - often times laying dormant until called upon by the malicious actor.

Creating the Virus

What’s scary is just how simple it was for Ben to create such a virus, one that mutated ever so slightly as it infected every other file on the server. Opening up unlimited possibilities from scraping customer data, to DDOS attacks, to simply hijacking your domain.



But those attacks are just the start as Ben demonstrated how easy it is to write new files, delete files, eval() and execute foreign code - which could even be extended to accessing the underlying server itself if shell_exec() is enabled.

To add to the problem, Ben shares how challenging it can be to identify malicious code on your server as many of these attacks are far more sophisticated than the the virus he created in a matter of minutes - hiding themselves and often appearing as if they are part of the original source code.

Deploying the Virus

To drive his point home, Ben demonstrates how even seemingly secure systems can be vulnerable - as all it takes is one tiny misstep within your application.

He highlights this by building what should be a secure photo gallery - one that checks the extension and mime-type of the image - and even stores it outside of the public directory. He goes even farther by adding additional sanity checks with a PHP script that then renders the image.

After walking through the code and it’s security features, he then downloads a simple image from the internet. Opening his editor he quickly injects the virus (written in PHP) into the image and uploads it, passing all of the server checks.

Surely, since it passed these checks the system is secure, right? Ben loads the gallery to proudly show off the image - which is just that… an image, with nothing special or out of the ordinary.
Except that when he opens the image gallery files, each has been infected with the malicious code.

The culprit that allowed for Ben to hijack an entire system and execute foreign code, create new files, and even hijack the entire site? When displaying the image the file was included using PHP’s include() function, instead of pulling in the data using file_get_contents() and echoing it out.

Such a simple mistake provided Ben, if he was a malicious hacker, complete access to all of the files on the system.

Protecting Yourself

Security always exists in layers - and this could have been prevented by including a few more layers, such as using an open source library to rewrite the image, reviewing the image source before pulling it in, or again not giving it executable access by using the PHP include() function.

But what’s terrifying is how simple it is to hijack a site, how easy it is to get access to your system and private data, and how easy it is to overlook security vulnerabilities - especially with open source tooling and those that take plugins.

As Ben explains, sometimes the core code itself is really secure, but then you get two different plugins that when used together accidentally create a security vulnerability. That by itself is one of the most challenging as you can audit each plugin individually, and still not know you’re opening up your system to malicious actors.

This is why it's not just important to stay up to date on the latest security measures and best practices, but to be constantly thinking like a hacker and testing your code for vulnerabilities.

For any development project to be successful, it’s important to choose the right technology and programming language. Most of the time, developers get confused about which programming language to choose.

Nowadays, PHP and Python have gained popularity among the programming languages for web development projects. However, choosing one between PHP vs Python is a difficult task. Recently, this has become a good topic for discussion.

Here, in this blog, we will compare the two popular programming languages: PHP vs Python. Let’s see which one turns out to be the best choice for web development.

What is Python?

Python is an open-source programming language developed in the year 1991 by Guido Van Rossum. It is one of the most commonly used languages due to its high level and easy-to-understand syntax.

According to the survey by Stack Overflow, Python is one of the most preferred programming languages. These Python app examples highlight its robustness and suitability for building scalable and innovative solutions across different platforms. Most of the companies and developers around the world are using Python web development.

What is PHP?

PHP or Hypertext Pre-processor, is an open-source server scripting language that is used for creating interactive and engaging web pages. This programming language comes with many features, libraries, plugins, and add-ons that increase community support and functionalities.

PHP language was developed by Rasmus Lerdorf in the year 1995. Earlier, PHP was named as Personal Home Page, which was later changed to Hypertext Pre-processor. An advantage of using PHP language is it supports all web browsers.

This comprehensive comparison between PHP vs Python can help you to choose the right language for web development. Now, we will compare some other elements that would give you a clear picture of both PHP vs Python.

1. Ease of Learning

Python is an easier language to learn compared to PHP. If you are a beginner, then Python is a good choice as you can learn it quickly. Python programs are shorter as well as easy to write in comparison to other languages.

PHP programming language is made for creating sophisticated web apps. It’s not a general-purpose language, and it takes time to learn it.

2. Ease of Use

Python is an open-source programming language that is versatile and portable. Python’s syntax is simple, and coding is easy to learn compared to PHP. But PHP is not just an ordinary programming language it’s used for creating dynamic web pages with HTML. This makes PHP more difficult to use than Python.

3. Community Support

Both PHP and Python provide good community support. PHP has been in the market for a long time and has a large community of developers. Therefore, you can immediately get support if you opt for PHP.

However, there are even many Python developers who constantly develop python apps. So, the community support in Python is also good. Consequently, we can’t say whether PHP or Python is better at providing community support.

4. Flexibility

Nowadays, web apps backed by Machine Learning are in high demand. Also, ML is a significant part of Python. Python provides many machine-learning libraries, such as Tensorflow, Theano, Pandas, and Scikit-learn. Additionally, these libraries are rapid, unique, & robust and work effectively with a web framework.

Nonetheless, Python programming language can be used in many other fields apart from web development. But when it comes to PHP, it’s best for web development. Therefore, we can say Python is a better choice here.

Our skilled developers delivers the most promising web development firms to make dynamic websites for your business.

5. Speed to Market

Python provides a comprehensive set of modules and third-party libraries to help developers finish the project faster. One of the popular web frameworks written in Python is Django. It utilizes the MVC pattern to allow developers to create apps fast using a significant division of concerns and reusability.

PHP also has a vast set of tools, frameworks, and libraries. Laravel is a popular PHP framework that allows the MVC pattern. Additionally, it comes with many helpful functionalities for web development, like routing, templating, authentication, and so on.

6. Web Frameworks

You get robust and well-designed web development frameworks both in PHP and Python. Most of the big businesses utilize web frameworks that PHP provides. For example, Laravel and Symfony are mature web frameworks, and a huge community supports them. So, we can say PHP makes web development easy.

Python also has many exceptional frameworks that are highly scalable, easy to use, fast and secure. It’s two most popular web frameworks are Flask and Django. If you want a shorter development period, then you can choose Django over PHP-based frameworks.

7. Library Management

Python uses Pip to handle and deal with packages. Pip ensures that Python app development is easy, rapid, and meets development needs. Python has powerful library management compared to PHP. It has a wide range of packages and tools that assist and make web app development easier. So, in terms of library management, Python clearly wins it.

8. Security

When it comes to security, most businesses prefer using Python. For instance, Django offers many pre-built security features that aid in safeguarding the apps from distinct security breaches & threats.

Apart from that, many government organizations rely on Python as their secret hacking tool. Most of the security problems are addressed by its large community support. However, PHP is less strong than Python in aspects of security.

9. Environment Management

In terms of handling environments, Python is the best programming language. It has a Virtualenv system that aids in installing different versions of the language and switching between them immediately.
PHP has no comparison with Python when it comes to handling environments. There’s an analog of PHP, VirtPHP, but it’s archived and not maintained. Therefore, most of the developers opt for Python.

10. Debugging

Python has an in-built debugger called Python Debugger or PDB. It utilizes many debugging strategies. PDB enables dynamic typing and lets developers work effortlessly without stating things at the start of a program.
PHP also comes with an XDebug package for handling bugs and error-checking the codes. But PHP development is quite slow in identifying and removing bugs. Therefore, it often experiences security issues.

The Bottom Line PHP vs Python: Which One You Choose for Web Development?

From the blog, you must have inferred that both PHP and Python are good for web development. However, there are many aspects in which Python wins over PHP. But this doesn’t mean that you only have to opt for Python. The selection of programming language majorly depends on the complexity and needs of the project.

Hello Guys,

In our Last Blog Post, we have created restful apis,But not worked on its security and authentication. Login api can be public but after login apis should be authenticate using any secure token. one of them is JWT, So i am providing the Steps for Create and use JWT Token in our already created API.


Now its time To Implement JWT Authentication IN our Api, So these are the steps to implement it in our already created Apis

Step 1:Install and include Firebase JWT(JSON WEB TOKEN) in our project with following composer command        

 composer require firebase/php-jwt 

include the composer installed packages

require_once('vendor/autoload.php');

use namespace using following:

 use \Firebase\JWT\JWT; 

Step 2: Create a JWT server side using Firebase Jwt Library's encode method in Login action , and return it to Client

Define a private variable named Secret_Key in Class like following:

 private {
 $payload = array(
 'iss' => $_SERVER['HOST_NAME'],
 'exp' => time()+600, 'uId' => $UiD
 );
 try{
 $jwt = JWT::encode($payload, $this->Secret_Key,'HS256'); $res=array("status"=>true,"Token"=>$jwt);
 }catch (UnexpectedValueException $e) {
 $res=array("status"=>false,"Error"=>$e->getMessage());
 }
 return $res;
 }

In our login action , if the user has been logged in successfully then with the status,_data_ and message just replace the login success code with following code:

$return['status']=1;
$return['_data_']=$UserData[0];
$return['message']='User Logged in Successfully.';

 $jwt=$obj->generateToken($UserData[0]['id']);
 if($jwt['status']==true)
 {
 $return['JWT']=$jwt['Token'];
 }
 else{
 unset($return['_data_']);
 $return['status']=0;
 $return['message']='Error:'.$jwt['Error'];
 }

Step 3: Now with every request after login should have the JWT token in its Post(even we can receive it in get or authentication header also but here we are receiving it in post)

No afetr successfully login you will get the JWt Token in your response,Just add that Token with every post request of after login api calls. So we will do it using postman, Find the screenshot 1 for checking the JWT Token is coming in login api response

Step 4:After reciving the JWt in every after login api call, we need to check whether the token is fine using JWT decode method in After login Apis like

UserBlogs

is a After login Api, So for verify that we are creating Authencate method in class like following:

 public function Authenticate($JWT,$Curret_User_id)
 {
 try {
 $decoded = JWT::decode($JWT,$this->Secret_Key, array('HS256'));
 $payload = json_decode(json_encode($decoded),true);
 
 if($payload['uId'] == $Curret_User_id) {
 $res=array("status"=>true);
 }else{
 $res=array("status"=>false,"Error"=>"Invalid Token or Token Exipred, So Please login Again!");
 }
 }catch (UnexpectedValueException $e) {
 $res=array("status"=>false,"Error"=>$e->getMessage());
 } 
 return $res;
 
 }

Step 5: Cross check the response returned by Authenticate method in

UserBlogs

Action of api , replace the

UserBlogs

Action inner content with following code:

 if(isset($_POST['Uid']))
 {

 $resp=$obj->Authenticate($_POST['JWT'],$_POST['Uid']);
 if($resp['status']==false)
 {
 $return['status']=0;
 $return['message']='Error:'.$resp['Error'];
 }
 else{
 $blogs=$obj->get_all_blogs($_POST['Uid']);
 if(count($blogs)>0)
 {
 $return['status']=1;
 $return['_data_']=$blogs;
 $return['message']='Success.';
 }
 else
 {
 $return['status']=0;
 $return['message']='Error:Invalid UserId!';
 }
 } 
 }
 else
 {
 $return['status']=0;
 $return['message']='Error:User Id not provided!';
 }

Ah great its time to check out the UserBlogs Api, please find the screenshoot for that, Remember we need to put the JWt Token in POST Parameter as we have already recived that Value in Login Api call.



Now if you want to verify that token is expiring in given time(10 minutes after generation time/login time), i am just clicking the same api with same token after 10 minutes and you can see there will not return any data and it is returning status false with following message :





Also if you want to eloborate it more then i suggest you to try with modify Uid value with same token , you will another authentication issue and also if you modify the JWT token also then also you will not get the desired result and get authentication Issue

Thanks for reading out if you want the complete code of this file then please find following:
