perock 0.2.1

Simple general purpose python bruteforce library

perock

Description

Perock is Python bruteforce attack library built on threads and asyncio. Its intended for simplifying bruteforce attack by performing common tasks in bruteforce such as calculating cartesian product.

Perock was built to be general purpose in that it can be used for wide variety of bruteforce attack activities. It can be used with html forms, file with passwords, API requiring username and password, etc.

All it takes is defining how to interact with the system/target and validate bruteforce data such as username and password. The rest will be handled for you including when to terminate based on certain conditions which would improve performance.

Pros

• Simple and easy to get started.
• Supports concurrency with asycio and threads.
• Performs faster with optimisations.
• General purpose(almost any bruteforce attack activity)
• Bruteforce data can be loaded from csv and json files.

Cons

• Performs slower than manually written code.
• Python 3.5 or less not supported.

Install

In your command-line application enter this:

pip install perock

Environment

• Tested with Python 3.6, 3.8 and 3.10.

Setup bruteforce data

# Create field with usernames
usernames_field = forcetable.FieldFile("usernames", "usernames.txt")
usernames_field.set_item_name("username")

# Create field with passwords
passwords_field = forcetable.FieldFile("passwords", "passwords.txt")
passwords_field.set_item_name("password")

# Create table and add fields
table = forcetable.Table()
table.add_field(usernames_field)
table.add_field(passwords_field)
# Sets usernames_field as primary field of table
table.set_primary_field(usernames_field)

# table will handle cartesian product of the fields
# table also contains records created from the fields

Threaded bruteforce attack

class LoginPageAttack(attack.Attack):
    def __init__(self, target, data: dict, retries=1) -> None:
        super().__init__(target, data, retries)
        # self._responce can also be None or Exception
        # Responce can be anything but None and Exception are special.
        self._responce: requests.Response

    @classmethod
    def create_session(cls):
        # Creates session object to use with requests
        # That can improve request performance
        return requests.Session()

    @classmethod

        session.close()

        pass

            return session.post(self._target, data=self._data)
        else:

        elif self.errors():

            print("Responce message:", self._responce_msg)


# Creates runner object to perform bruteforce

    LoginPageAttack, "http://127.0.0.1:5000/login", table)

# Enables optimisation(requires primary field)

Asynchronous bruteforce attack

class LoginPageAttackAsync(attack.AttackAsync):
    def __init__(self, target, data: dict, retries=1) -> None:
        super().__init__(target, data, retries)
        # self._responce can also be None or Exception
        # Responce can be anything but None and Exception are special.
        self._responce: aiohttp.ClientResponse
        self._session: aiohttp.ClientSession

    @classmethod
    async def create_session(cls, *args, *kargs):
        # Creates session object to use with request
        return aiohttp.ClientSession(*args, *kargs)

    @classmethod
    async def close_session(cls, session):
        await session.close()


    @classmethod
    async def close_responce(cls, responce):
        #await responce.close()
        pass


    async def request(self):
        if self.session_exists():
            return await self._session.post(self._target, data=self._data)
        else:
            async with await self.create_session() as session:
                return await session.post(self._target, data=self._data)

    async def failure(self):
        if await self.target_reached():
            if b"Failed to login" in await self._responce.read():
                return True
            elif b"No such username" in await self._responce.read():
                return True
        return False

    async def success(self):
        if await self.target_reached():
            return b"Login successful" in await self._responce.read()
        return False

    async def target_errors(self):
        if await self.target_reached():
            return self._responce.status != 200
        return False

    async def after_request(self):
        await super().after_request()
        if await self.failure():
            #print("Attempt failed:", self._data)
            pass
        elif await self.success():
            print("Attempt success:", self._data)
        elif await self.errors():
            print("Attempt errors:", self._data)
            print("Responce message:", self._responce_msg)


# Creates runner object to perform bruteforce
runner_object = runner.RunnerAsync(
    LoginPageAttackAsync, "http://127.0.0.1:5000/login", table)

# Enables optimisation(requires primary field)
runner_object.enable_optimise()
asyncio.run(runner_object.run())

Free fields resources

# FileField is backed by file object.
# Its important to close it after use.
usernames_field.close()
usernames_field.close()

The examples above can be easily modified based on bruteforcing websites login forms or something unique and different.
