Rever Security

Hi guys, What is the tool do? We write a new Tool this tool you gives it a subdomains list and the tool check all of the lists and if it notices that the subdomain may be vulnerable with subdomain takeover it will tell you about it. Requirements Python2.7 / 3.7 requests lib [pip install requests] colorama lib [pip install colorama] Now to Download you can download it from here:  Tool

Hey Guys, Today I would like to show you how I found a Stored XSS on Edmodo main domain. when I test the website I create two accounts when I signup I added the XSS payload on the name, I opened the victim account on FireFox and attacker account on Google Chrome and I opened the victim profile and send a request to connect together like add friend now when the victim open my profile to accept the request the XSS payload which was in the name will be executed The POC Video I hope this topic helped you, thank you for reading.

In this topic, I will share with your the write-up about the HITB2018DXB Pre-Conf CTF from Cyber Talents I will solve the web security challenges. First challenge [ who am i for 50 points] : at the first when we open the challenge we will found a login form so the first thing I tried to do it's open the source and look on it and I found that so I used this account to enter the panel but I found that I should be an admin to see the flag I think for a few minutes and I try to see the cookies and I found this the value is encoded with base64 so when I decode it I found this value  login=Guest now I changed the Guest to admin and encode it again and I tried to open the page again and I found the flag the flag is:  FLag{B@D_4uTh1Nt1C4Ti0n} ----------- The second challenge [Dark project for 100 points]: when you open the challenge you will find that there is a page when you open one from it there is a new parameter and the page nam...

Some websites depend on JSON to send requests and receive responses and this response can include an information about the logged in user and shouldn't be public to anyone now in this topic we will see how we can steal this data. What is JSON? JSON is a language but isn’t programing language but it’s a lightweight data-interchange format and we can use it to communication between different apps such as ( Android, IOS, Web,….). Exploitation Now some of JSON response is like that In this case, if the response like that you are lucky we can dump this data by writing a small code using JS we will include this file in my page as a JS file in a script tag and we will create a function to dump data and the function name should be  userInfo  this is the exploitation you can see the code in the next image and the response in my page here Attacker page This a useful way and the Basic there are more ways but I don’t want t...

Summary: hey guys I hope you are fine, now I am going to talk about how to start with Web applications security. now if you want to learn something from someone but this guy doesn’t speak the same language of you what will you do?…….yes…you will learn his language to learn from him, it’s the same with web applications now if you want to start “security web application” you should learn how it works, learn it’s language. Now I will talk about the programming language: There are a lot of programming languages you can use Java, ASP, Perl, Ruby, Python, and PHP but the best one is PHP because most of the web applications use it but the other languages have a good future now you learned PHP to understand what website say :D, now you should learn a programming language for the Database to use it with PHP now the Database is something that the website can’t work without it. so you can learn MySQL it’s good but there are others you can search about them “Google Is Yo...

Hey guys the last tutorial we talk about the  Ceaser Cipher Algorithm in this tutorial we will talk about  Polyalphabetic Cipher we will talk about the Encryption & Decryption process like part one. Encryption : now let's imagen that we want to encrypt this word security we will use the same  sequence 0 1  2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 A B C D E F G H I J K L M N O P Q R S T U V W X Y Z now we will split security word to groups three letters in the group to be like that sec uri ty there is two letters we will skip it and continue, the encryption way it's 1. the first letter will be moved 3 letters to the right 2. the second letter will be moved 5 letters to the right 3. the third letter will be moved 7 letters to the right (if the numbers is finished we will start from the first from zero) so the encryption to this letters sec is: S => V E => J C => J the sam...

Hi guys how are you? I hope you are fine in this topic we will talk about the Cryptography this field is a huge field we will split this field into parts of topics let's start. In this part of the topic, we will talk about a simple algorithm in the Cryptography field it's Ceaser Cipher this algorithm is one of the old algorithms and the Ceaser king was use it in encrypt the messages, let's see how we can use this encryption. Encryption : we will imagen that we want to encrypt this word Hello to encrypt this word we should have the encryption key (k) let's imagine gen that it's equal 3 so k=3 see this 0 1  2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 A B C D E F G H I J K L M N O P Q R S T U V W X Y Z we will found that every letter equal number we will use this equation CipherText = E(k,p) = (p+k) mod 26 p is the letter place and k is the encryption & decryption key and 26 it's the number of English letters so this let...
