Cracking the Zoom Host Code:

Tutorial Outline:

1) Download and install the necessary packages.

2 ) Generate all of the possible host codes.

3 ) Interact with the Zoom user interface using pyautogui/pyperclip/pynput.

4 ) Analyze the performance of the script.

In

the late-2000’s, I spent more time than I care to admit playing Halo online. During this time I was exposed to (but did not participate in) the small but unavoidable modding community within the game. People who had found ways to cheat, or alter the game to either win or sometimes just to implement fun new features. One of the techniques used was “Standby” cheating, which was when software was used to block the internet connections of the players on the opposing team, send large amounts of information to their connections, and force them to drop out of the game. If you were playing a 4v4 matchmaking game 3 of your teammates could be dropped from the game and the opposing team would just wait around to either kill you or run the clock for the win.

What does this have to do with Zoom? In order for “Standby” cheating to work, you would needed to be the “host” of the game. In Halo, host was usually given to whichever player had the fastest internet connection, and if you were able to slow down all other player connections, you could force yourself to become host. When I first started using Zoom, I saw the “claim host” button and was taken back to the times spent playing Halo. After all, Zoom is basically just a visual version of the game lobby — sans profanity (nsfw). In this article we are going to crack the Zoom host code, in a way that is functional but not practical.

Note: The following code is inefficient and may crash when run, especially when generating 8–10 digit numbers. Please be cautious if copying and pasting code, you can also use the command line version of this script, which has some built-in safeguards to prevent unwanted behavior.

Requirements.

First, we will need to download and import pyperclip, pyautogui, and pynput. Pyperclip will be used to save each host key we generate to our clipboard, and pyautogui will allow out program to interact with the Zoom user interface. I will be using a Mac connected to a 4K monitor for this project (this will be important to consider later, as pyautogui uses screenshots to locate items on the screen). Pynput will be used to click the input box bordered in blue seen in the below screenshot.

Static Code Analysis: What It Is? How to Use It?

Static code analysis refers to the technique of approximating the runtime behavior of a program. In other words, it is the process of predicting the output of a program without actually executing it.

Lately, however, the term “Static Code Analysis” is more commonly used to refer to one of the applications of this technique rather than the technique itself — program comprehension — understanding the program and detecting issues in it (anything from syntax errors to type mismatches, performance hogs likely bugs, security loopholes, etc.). This is the usage we’d be referring to throughout this post.

“The refinement of techniques for the prompt discovery of error serves as well as any other as a hallmark of what we mean by science.”

• J. Robert Oppenheimer

Outline

We cover a lot of ground in this post. The aim is to build an understanding of static code analysis and to equip you with the basic theory, and the right tools so that you can write analyzers on your own.

We start our journey with laying down the essential parts of the pipeline which a compiler follows to understand what a piece of code does. We learn where to tap points in this pipeline to plug in our analyzers and extract meaningful information. In the latter half, we get our feet wet, and write four such static analyzers, completely from scratch, in Python.

Note that although the ideas here are discussed in light of Python, static code analyzers across all programming languages are carved out along similar lines. We chose Python because of the availability of an easy to use ast module, and wide adoption of the language itself.

How does it all work?

Before a computer can finally “understand” and execute a piece of code, it goes through a series of complicated transformations:

As you can see in the diagram (go ahead, zoom it!), the static analyzers feed on the output of these stages. To be able to better understand the static analysis techniques, let’s look at each of these steps in some more detail:

Scanning

The first thing that a compiler does when trying to understand a piece of code is to break it down into smaller chunks, also known as tokens. Tokens are akin to what words are in a language.

A token might consist of either a single character, like (, or literals (like integers, strings, e.g., 7, Bob, etc.), or reserved keywords of that language (e.g, def in Python). Characters which do not contribute towards the semantics of a program, like trailing whitespace, comments, etc. are often discarded by the scanner.

Python provides the tokenize module in its standard library to let you play around with tokens:

Python

1

import io

2

import tokenize

3

4

code = b"color = input('Enter your favourite color: ')"

5

6

for token in tokenize.tokenize(io.BytesIO(code).readline):

7

    print(token)

Python

1

TokenInfo(type=62 (ENCODING),  string='utf-8')

2

TokenInfo(type=1  (NAME),      string='color')

3

TokenInfo(type=54 (OP),        string='=')

4

TokenInfo(type=1  (NAME),      string='input')

5

TokenInfo(type=54 (OP),        string='(')

6

TokenInfo(type=3  (STRING),    string="'Enter your favourite color: '")

7

TokenInfo(type=54 (OP),        string=')')

8

TokenInfo(type=4  (NEWLINE),   string='')

9

TokenInfo(type=0  (ENDMARKER), string='')

(Note that for the sake of readability, I’ve omitted a few columns from the result above — metadata like starting index, ending index, a copy of the line on which a token occurs, etc.)

Zoom Clone, Zoom Clone Script, Build Best App Like Zoom

A video conferencing app is a revolutionary virtual cloud-based solution that lets users to host virtual meetings and audio/video conferencing. It is easy to launch the Zoom like app in the wink using the Zoom clone script. This blog will give you insightful information about the Zoom clone app development process.

**Zoom clone app development with the essential features to incorporate
**

At the onset of the coronavirus, people mostly heard social distancing, lockdown, mask, work from home and so on. To prevent virus transmission, they are forced to stay indoors. Shopping malls, theatres, and educational institutions (colleges and schools) were closed. Despite this, employees are working from home. Yes, it is quite challenging for them.

With adapting to the new normalcy, employees have preferred the video conferencing app for conducting and attending online meetings. This is one of the major reasons for the sudden growth of video conferencing app like Zoom.

Seeing this demand for video call apps, entrepreneurs find this an opportunity to launch their app, similar to Zoom. Because, Zoom is the most downloaded app in the United States from March to April 2020.

After relaxing the restrictions at the end of 2020, the coronavirus spread is considerably increasing recently. Therefore, the demand for video conferencing surges.

The pandemic is not the only reason for the growth of the video conferencing app. Many companies and employees prefer this app as it saves time and money that has to be invested in setting up meeting rooms.

**Essential features to consider for Zoom like app development
**

Feature-set integration is an important point to consider for Zoom like app development. Because, the app features determine the app’s functionality.

Integrating new and innovative features will make your app stand out from the other video conferencing apps. Moreover, this does not necessarily mean that you should compromise any of the basic features.

The essential features that should be incorporated into your video conferencing app are as follows.

Chat

Using this feature, the users can connect with other users. While attending the meeting, they can chat with all the participants in the meeting or chat individually, depending on their choice.

**Virtual hand-raising
**

It is the most useful feature. Participants can speak at any time in the meeting using this feature. When one participant is presenting her/his topic in the meeting, it is not good to see the other participants interrupting. This prevents multiple participants from speaking at the same time.

**Screen sharing
**

This feature will let the participant in the meeting share the screen with other members.

**Mute participants
**

The background might be noisy for some participants. So, the host has the option to mute any participants during the meeting as per his/her desire.

**Scheduled meetings
**

Using this feature, the host can schedule their meetings with their participants. Also, the participant who initiates has the option to set reminders for the scheduled meetings.

**Video sharing
**

The Video Sharing feature will allow the participants to share the videos from YouTube in the session. This will make the session interactive. Notably, participants do not have to download the YouTube video for watching. Instead, the video conferencing app will display the video.

**Encryption
**

The app should not let unauthorized users join the meeting. Therefore, your app should be embedded with end-to-end encryption. By doing this, no one can join the meeting without the permission of the host.

**Zoom clone app development - How much does it cost?
**

When it comes to the Zoom like app development cost, it mainly depends on your app features and functionality.

There is a rough estimation that the app cost is less when you plan to incorporate the basic features. You have to invest a particular amount of money in including the advanced and new features.

Other important features that determine the price are the geographical location, app platform, and time frame.

**Final note
**

Hoping so, this article helps you in knowing the feature-set to integrate into a video conferencing app like Zoom. However, there is no doubt that the requirement for video conferencing apps is high.

As Zoom being the most popular app, incorporate the same features in your app and include additional features that Zoom has failed to work. Approach Uber Like App for Zoom like app development.

How to Find the Stinky Parts of Your Code (Part II)

There are more code smells. Let’s keep changing the aromas. We see several symptoms and situations that make us doubt the quality of our development. Let’s look at some possible solutions.

Most of these smells are just hints of something that might be wrong. They are not rigid rules.

This is part II. Part I can be found here.

Code Smell 06 - Too Clever Programmer

The code is difficult to read, there are tricky with names without semantics. Sometimes using language’s accidental complexity.

_Image Source: NeONBRAND on _Unsplash

Problems

• Readability
• Maintainability
• Code Quality
• Premature Optimization

Solutions

1. Refactor the code
2. Use better names

Examples

• Optimized loops

Exceptions

• Optimized code for low-level operations.

Sample Code

Wrong

function primeFactors(n){
	  var f = [],  i = 0, d = 2;  

	  for (i = 0; n >= 2; ) {
	     if(n % d == 0){
	       f[i++]=(d); 
	       n /= d;
	    }
	    else{
	      d++;
	    }     
	  }
	  return f;
	}

Right

function primeFactors(numberToFactor){
	  var factors = [], 
	      divisor = 2,
	      remainder = numberToFactor;

	  while(remainder>=2){
	    if(remainder % divisor === 0){
	       factors.push(divisor); 
	       remainder = remainder/ divisor;
	    }
	    else{
	      divisor++;
	    }     
	  }
	  return factors;
	}

Detection

Automatic detection is possible in some languages. Watch some warnings related to complexity, bad names, post increment variables, etc.
