Automating MS Teams

Arun krishna — Wed, 02 Sep 2020 12:40:01 +0000

My Workflow

Most of us are aware that Teams is a video conferencing app which allows us to attend/conduct meetings. And because of this pandemic situation, the usage of these video conferencing apps also increased and most of the classes and lectures and conferences are conducted in Teams now a days.

Let us see how I have automated Teams so that it automatically logs into one's meetings/classes on time.

An infinite loop keeps checking the current time of the system using datetime.now() funtion.
The Teams app is opened using os.startfile().
pyautogui.locateCenterOnScreen() function locates the center of the first found instance of the image on the screen.
pyautogui.moveTo() moves the cursor to that location.
pyautogui.click() performs a click operation.

Automating MS Teams

Most of us are aware that Teams is a video conferencing app which allows us to attend/conduct meetings. And because of this pandemic situation, the usage of these video conferencing apps also increased and most of the classes and lectures and conferences are conducted in Teams now a days.

New Features!

Let us see how I have automated Teams so that it automatically logs into one's meetings/classes on time.

Pre-requisites:

Microsoft Teams application - Download the exe file from official website Python 3.x Pyautogui Intervals

Install Packages:

pip install pyautogui
pip install python-intervals

Execution:

python teams.py

Working (Behind the scenes) :

An infinite loop keeps checking the current time of the system using datetime.now() funtion The Teams app is opened using os.startfile() pyautogui.locateCenterOnScreen() function locates the center of the first found instance of the image on the screen pyautogui.moveTo() moves the cursor to that location pyautogui.click() performs…

Additional Resources / Info

Pre-requisites:

Microsoft Teams application - Download the exe file from here
Python
Pyautogui

Pyautogui :
PyAutoGUI is a cross-platform GUI automation Python module. It programmatically controls the mouse & keyboard. It has screen shot features and also image finding features.

pip install pyautogui
pip install python-intervals

Note :
Before using the script make sure that the Teams application is closed in such a way that all the teams are displayed as shown in the below figure.

Import the necessary modules

import os             
import pyautogui
import intervals as I
import time
from time import sleep
from datetime import datetime

Open Teams

os.startfile("C:/Users/username/AppData/Local/Microsoft/Teams/current/Teams.exe")

Next, take the screenshot of settings button and use the below chunk of code to move the mouse to that button and click it.

settings = pyautogui.locateCenterOnScreen("settings.PNG") 
pyautogui.moveTo(settings)
pyautogui.click()
time.sleep(2)

Now we need to click on Manage Teams button to get a list of teams vertically.

manageteams = pyautogui.locateCenterOnScreen("manageteams.PNG") 
pyautogui.moveTo(manageteams)
pyautogui.click()
time.sleep(2)

then we will get the screen like this

Now we run the below code snippet in an infintie loop.

We get the current time and compare it with the class ending time . For example if current time is 17:00 and my class is at 17:00 but the meeting has started. If I give my class ending time i.e 18:00 then as soon as meeting starts the scripts automatically clicks on join button with camera and microphone turned off.

Join button is given below.

Camera and microphone button is given below.

Similarily take the screenshot of your class name too.

if now < '18:00':
    Andromeda =pyautogui.locateCenterOnScreen("Andromeda.PNG") 
    pyautogui.moveTo(Andromeda)
    pyautogui.click()
    time.sleep(2)
    join = pyautogui.locateCenterOnScreen("join.PNG") 
    pyautogui.moveTo(join)
    pyautogui.click()
    time.sleep(2)
    audiooff = pyautogui.locateCenterOnScreen("audiooff.PNG") 
    pyautogui.moveTo(audiooff)
    pyautogui.click()
    time.sleep(2)

Similarily you can do it for n number of classes.
In the below code I have done it for 2 classes.

import os             
import pyautogui
import intervals as I
import time
from time import sleep
from datetime import datetime


try:
    # open MS Teams application
    os.startfile("C:/Users/username/AppData/Local/Microsoft/Teams/current/Teams.exe") 
    sleep(2)
    # settings
    settings = pyautogui.locateCenterOnScreen("settings.PNG") 
    pyautogui.moveTo(settings)
    pyautogui.click()
    time.sleep(2)
    # manageteams.PNG
    manageteams = pyautogui.locateCenterOnScreen("manageteams.PNG") 
    pyautogui.moveTo(manageteams)
    pyautogui.click()
    time.sleep(2)
except Exception as e:
    print(e)

while True:
    #andromeda
    now = datetime.now().strftime("%H:%M")
    if now < '18:00':
        Andromeda = pyautogui.locateCenterOnScreen("Andromeda.PNG") 
        pyautogui.moveTo(Andromeda)
        pyautogui.click()
        time.sleep(2)
        join = pyautogui.locateCenterOnScreen("join.PNG") 
        pyautogui.moveTo(join)
        pyautogui.click()
        time.sleep(2)
        audiooff = pyautogui.locateCenterOnScreen("audiooff.PNG") 
        pyautogui.moveTo(audiooff)
        pyautogui.click()
        time.sleep(2)
    elif now <'17:00': 
        Automation = pyautogui.locateCenterOnScreen("Automation.PNG") 
        pyautogui.moveTo(Automation)
        pyautogui.click()
        time.sleep(2)
        join = pyautogui.locateCenterOnScreen("join.PNG") 
        pyautogui.moveTo(join)
        pyautogui.click()
        time.sleep(2)
        audiooff = pyautogui.locateCenterOnScreen("audiooff.PNG") 
        pyautogui.moveTo(audiooff)
        pyautogui.click()
        time.sleep(2)

Suppose if you want to set the time interval and check for meeting to start and then join please see this

while True:
    #andromeda
    k = datetime.now().strftime("%H")
    now = int(k)
    if now in I.closed(16, 17):
        andromeda = pyautogui.locateCenterOnScreen("Andromeda.PNG") 
        pyautogui.moveTo(andromeda)
        pyautogui.click()
        time.sleep(2)
        join = pyautogui.locateCenterOnScreen("join.PNG") 
        pyautogui.moveTo(join)
        pyautogui.click()
        time.sleep(2)
        audiooff = pyautogui.locateCenterOnScreen("audiooff.PNG") 
        pyautogui.moveTo(audiooff)
        pyautogui.click()
        time.sleep(2)
        if now == 17:
            cut = pyautogui.locateCenterOnScreen("cut.PNG") 
            pyautogui.moveTo(cut)
            pyautogui.click()
            time.sleep(2)
            dismiss = pyautogui.locateCenterOnScreen("dismiss.PNG") 
            pyautogui.moveTo(dismiss)
            pyautogui.click()
            time.sleep(2)
            back = pyautogui.locateCenterOnScreen("back.PNG") 
            pyautogui.moveTo(back)
            pyautogui.click()
            time.sleep(2)

Then the entire code will be as below:

import os             
import pyautogui
import intervals as I
import time
from time import sleep
from datetime import datetime


try:
    # open MS Teams application
    os.startfile("C:/Users/username/AppData/Local/Microsoft/Teams/current/Teams.exe") 
    sleep(2)

    settings = pyautogui.locateCenterOnScreen("settings.PNG") 
    pyautogui.moveTo(settings)
    pyautogui.click()
    time.sleep(2)
    # manageteams.PNG
    manageteams = pyautogui.locateCenterOnScreen("manageteams.PNG") 
    pyautogui.moveTo(manageteams)
    pyautogui.click()
    time.sleep(2)
except Exception as e:
    print(e)

while True:
    #andromeda
    k = datetime.now().strftime("%H")
    now = int(k)
    if now in I.closed(16, 17):

How to send a secret Whats app message from terminal using Gecko Driver

Arun krishna — Tue, 25 Aug 2020 17:22:49 +0000

Disclaimer:

Hello everyone,
In this post I will be showing how I have sent an encrypted secret whatsapp message.

Prerequisites:

Gecko web driver
Python 3.X
pycryptodome library
cryptography library
colorama library

Firstly the architecture of the system is as shown in the below figure

In this post I will demonstrate with AES algorithm. Similarly you can try with different encryption algorithms. And we are going to use Gecko driver to send the message automatically. The primary goal is encrypting and communicating the sensitive data in whatsapp.The encryption of AES used here is EAX mode.

Speciality:
This mode is difficult in encryption because it doesnot use UTF-8 encoding. It utilizes Windows-1252 encoding which is difficult for any external compilers to decode the message.

Libraries:
First let's install the required libraries. Write the 3 libraries pycryptodome
cryptography
colorama
in text file named requirements.txt
Now install them using pip command

pip install -r requirements.txt

Put the Gecko driver in the directory where you are going to execute the code.
All the pre-requisites are done let's dive into the coding part

Import the libraries

import base64
import binascii
import binhex
import os
import string
import sys
from random import choice
import smtplib
import os
import hashlib

Let's display an error message if any libraries are missing

try:
    from colorama import Fore, Style, init
    from Crypto.Cipher import AES
    from Crypto.Random import random
    from cryptography.fernet import Fernet
except ImportError:
    print(
        "ERROR: Missing required libraries.\n"
        "Install dependencies with: pip install -r requirements.txt"
    )
    sys.exit(1)

colorList = [Style.BRIGHT + Fore.RED, Style.BRIGHT , Style.BRIGHT + Fore.YELLOW, Style.BRIGHT + Fore.BLUE, Fore.GREEN ,Fore.MAGENTA, Style.BRIGHT + Fore.CYAN, Style.BRIGHT + Fore.WHITE]

Here I am using colorama library to change the colours for every execution.

Let's get the required input

def get(datatype):
    try:
        (message) = {
            "plaintext": ("Enter plaintext message"),
            "encoded": ("Enter encoded message"),
            "encrypted": ("Enter encrypted message"),
            "filename": ("Specify filename"),
            "passwordfilename": ("Specify  passwordfilename"),
            "password": ("Enter encryption password"),
            "Select": ("Choose any one"),
        }[datatype]
    except KeyError:
        message = datatype
    return input(f"\n{message}: {Style.RESET_ALL}").encode()

SENDER:
In my previous post I have mentioned about Xpath and automation. We are going to use similar concept here with whatsapp too. First let us write the bot script and store it in bot.py

from datetime import datetime
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.common.exceptions import NoSuchElementException
from time import sleep
import chardet

driver = webdriver.Firefox()
driver.get('http://web.whatsapp.com')
sleep(15)
driver.find_element_by_xpath("/html/body/div/div/div/div/div/div/div[1]/div/div/div[1]/div/div/div").click()
sleep(5)

fileLocation= "Path/AESKEY.txt"
with open(fileLocation,"r") as file:
    for line in file:
        driver.find_element_by_xpath("//*/footer/div[1]/div[2]/div/div[2]").send_keys(line)
        driver.find_element_by_xpath("//*/footer/div[1]/div[2]/div/div[2]").send_keys(Keys.ENTER)
sleep(5)


fileLocation= "Path/AES.txt"
with open(fileLocation,"r") as file:
    for line in file:
        for word in line.split(" "):
            driver.find_element_by_xpath("//*/footer/div[1]/div[2]/div/div[2]").send_keys(word)
            driver.find_element_by_xpath("//*/footer/div[1]/div[2]/div/div[2]").send_keys(Keys.ENTER)


# No special characters and spaces in enc

python
We are going to store the key required to decrypt the message in AESKEY.txt file and the encrypted message in AES.txt file. This bot reads the file and then sends the message. You can send some instruction message as shown below.

Now let's get into the encryption part.

def aes_enc_auto():
    """Encrypt with AES."""
    keypass = random_key(16)
    data = get("plaintext")
    filename = get("filename").decode()
    cipher = AES.new(keypass.encode(), AES.MODE_EAX)
    ciphertext, tag = cipher.encrypt_and_digest(data)
    with open(filename, "wb") as outfile:
        _ = [outfile.write(item) for item in (cipher.nonce, tag, ciphertext)]

    save_path='Path/Whatsapp'
    kn = "AESKEY"
    passwordfilename = os.path.join(save_path, kn+".txt") 
    with open(passwordfilename, "wt") as outfile:
        _ = [outfile.write(item) for item in (keypass)]
    print("AES encrypted message and key files are saved")
    os.system('python bot.py')
MENU_OPTIONS.append(aes_enc_auto)

First we get the plain text from the terminal and it is stored after getting encrypted. Then gecko driver comes into action and sends the content to receiver.

RECEIVER:
The above encrypted message can be decrypted by using below code.

def aes_dec_auto():
    """Decrypt with AES."""
    filename = get("filename")
    keypass = get("password")
    with open(filename, "rb") as infile:
        nonce, tag, ciphertext = [infile.read(x) for x in (16, 16, -1)]
    cipher = AES.new(keypass, AES.MODE_EAX, nonce)
    data = cipher.decrypt_and_verify(ciphertext, tag).decode()
    show("plaintext", data)
MENU_OPTIONS.append(aes_dec_auto)

Finally let's finish the main function

# Main Function
def main():
    try:
        while True:
            print(
                "\n"
                + Fore.GREEN + "Choose from the following options, or press Ctrl-C to quit:\n\n"
                + Style.RESET_ALL
            )
            for index, option in enumerate(MENU_OPTIONS, 1):
                print(Style.BRIGHT + f"{index}: {' ' if index < 10 else ''}" f"{option.__doc__}" + Style.RESET_ALL)
            choice = get("Select")
            print()
            try:
                MENU_OPTIONS[int(choice) - 1]()
            except (IndexError,UnboundLocalError):
                print("Unknown option." + Style.RESET_ALL)
            # except ValueError:
            #     print("Invalid option."+ "Enter the number of your selection."+ Style.RESET_ALL)

    except (KeyboardInterrupt,UnboundLocalError):
        print("\n{}Program Terminated\n{}Have A Nice Day{}".format(Fore.RED,Style.BRIGHT,Style.RESET_ALL))

        sys.exit(1)


if __name__ == "__main__":
    main()

In my below repository I have implemented the above concept with various hashing and encryption algorithms. Please drop a star if you like it.

Instagram bot to like and comment on all the posts of an user

Arun krishna — Sat, 15 Aug 2020 17:29:25 +0000

Disclaimer:
This code is for educational purposes only and the author is not responsible for any consequences resulted. Please do not try it if you do not agree for the condition.

Hello everyone,
In this post I will be showing how I automated instagram to like and comment on all the posts of a particular user

Prerequisites:
*Selenium
*Python
*Webdriver

I am using Google chrome web driver to automate our work, even Gecko driver which is Mozilla firefox webdriver. First install the webdriver in your workspace and import selenium in the workspace.

import selenium

Next we need to import keys and webdriver from selenium. Keys are used to send our text into the input fields

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

Next we need to find out the xpath of the elements from the site in order to send our parameters. We can either call the required element by it's class name or by using the xpath.

Xpath
Xpath can be extracted by clicking on inspect element and then by clicking on Copy full xpath option. After getting the xpath we use driver.find_element_by_xpath command.

For clicking on any Button or Link we use click() function.

We use driver.get command to open Instagram. And then we open our required user profile by using
driver.get("https://www.instagram.com/"+OtherUserId)

Now we get the number of posts of that particular user

posts = self.driver.find_element_by_xpath("/html/body/div/section/main/div/header/section/ul/li/span/span").text
posts = Decimal(sub(r'[^\d.]', '', posts))

Like

Next we open the individual posts by using the classname driver.find_element_by_class_name("_9AhH0"). Next we click on the like button

like = self.driver.find_element_by_xpath('/html/body/div[4]/div[2]/div/article/div[3]/section[1]/span[1]/button')
like.click()

Next similarly, for Comment we pull the xpath of the comment section and then send the text we need to comment and then comment is posted.

cmt = self.driver.find_element_by_xpath('/html/body/div[4]/div[2]/div/article/div[3]/section[1]/span[2]/button')
cmt.click() self.driver.find_element_by_xpath("/html/body/div[4]/div[2]/div/article/div[3]/section[3]/div/form/textarea").send_keys(comment)    self.driver.find_element_by_xpath("/html/body/div[4]/div[2]/div/article/div[3]/section[3]/div/form/textarea").send_keys(Keys.ENTER)

Similarily we need to iterate it for all the posts.

Python code:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from time import sleep
from re import sub
from decimal import Decimal

class Instabot:
    def __init__(self,username,password,OtherUserId,comment):
        self.driver=webdriver.Chrome("chromedriver.exe")
        self.driver.maximize_window()
        self.driver.get("https://www.instagram.com/")
        sleep(2)
        self.driver.find_element_by_xpath("//input[@name=\"username\"]").send_keys(username)
        self.driver.find_element_by_xpath("//input[@name=\"password\"]").send_keys(password)
        self.driver.find_element_by_xpath("//button[@type=\"submit\"]").click()
        sleep(5)
        self.driver.find_element_by_xpath("//button[text()='Not Now']").click()
        sleep(5)
        self.driver.find_element_by_xpath("//button[text()='Not Now']").click()
        sleep(5)
        self.driver.get("https://www.instagram.com/"+OtherUserId)
        posts = self.driver.find_element_by_xpath("/html/body/div/section/main/div/header/section/ul/li/span/span").text
        posts = Decimal(sub(r'[^\d.]', '', posts))
        print(posts)
        pic = self.driver.find_element_by_class_name("_9AhH0")    
        pic.click()
        sleep(2)
        like = self.driver.find_element_by_xpath('/html/body/div[4]/div[2]/div/article/div[3]/section[1]/span[1]/button')
        like.click()
        cmt = self.driver.find_element_by_xpath('/html/body/div[4]/div[2]/div/article/div[3]/section[1]/span[2]/button')
        cmt.click()
        sleep(1)
        self.driver.find_element_by_xpath("/html/body/div[4]/div[2]/div/article/div[3]/section[3]/div/form/textarea").send_keys(comment)
        self.driver.find_element_by_xpath("/html/body/div[4]/div[2]/div/article/div[3]/section[3]/div/form/textarea").send_keys(Keys.ENTER)
        nextPic = self.driver.find_element_by_xpath('/html/body/div[4]/div[1]/div/div/a')
        nextPic.click()
        print("success") 
        sleep(2)
        for i in range(int(posts-1)):
            like = self.driver.find_element_by_xpath('/html/body/div[4]/div[2]/div/article/div[3]/section[1]/span[1]/button')
            sleep(2)
            like.click()
            sleep(2)
            cmt = self.driver.find_element_by_xpath('/html/body/div[4]/div[2]/div/article/div[3]/section[1]/span[2]/button')
            cmt.click()
            sleep(1)
