BYOB (Build Your Own Botnet) Disclaimer: This project should be used for authorized testing or educational purposes only. BYOB is an open-source project that provides a framework for security researchers and developers to build and operate a basic botnet to deepen their understanding of the sophisticated malware that infects millions of devices every year and spawns modern botnets, in order to improve their ability to develop counter-measures against these threats. It is designed to allow developers to easily implement their own code and add cool new features without having to write a RAT (Remote Administration Tool) or a C2 (Command & Control server) from scratch. The RAT's key feature is that arbitrary code/files can be remotely loaded into memory from the C2 and executed on the target machine without writing anything to the disk. Supports Python 2 & 3. Client Generate fully-undetectable clients with staged payloads, remote imports, and unlimited post-exploitation modules Remote Imports: remotely import third-party packages from the server without writing them to the disk or downloading/installing them Nothing Written To The Disk: clients never write anything to the disk - not even temporary files (zero IO system calls are made) because remote imports allow arbitrary code to be dynamically loaded into memory and directly imported into the currently running process Zero Dependencies (Not Even Python Itself): client runs with just the python standard library, remotely imports any non-standard packages/modules from the server, and can be compiled with a standalone python interpreter into a portable binary executable formatted for any platform/architecture, allowing it to run on anything, even when Python itself is missing on the target host Add New Features With Just 1 Click: any python script, module, or package you copy to the ./byob/modules/ directory automatically becomes remotely importable & directly usable by every client while your command & control server is running Write Your Own Modules: a basic module template is provided in ./byob/modules/ directory to make writing your own modules a straight-forward, hassle-free process Run Unlimited Modules Without Bloating File Size: use remote imports to add unlimited features without adding a single byte to the client's file size Fully Updatable: each client will periodically check the server for new content available for remote import, and will dynamically update its in-memory resources if anything has been added/removed Platform Independent: everything is written in Python (a platform-agnostic language) and the clients generated can optionally be compiled into a portable executable (Windows) or bundled into a standalone application (macOS) Bypass Firewalls: clients connect to the command & control server via reverse TCP connections, which will bypass most firewalls because the default filter configurations primarily block incoming connections Counter-Measure Against Antivirus: avoids being analyzed by antivirus by blocking processes with names of known antivirus products from spawning Encrypt Payloads To Prevent Analysis: the main client payload is encrypted with a random 256-bit key which exists solely in the payload stager which is generated along with it Prevent Reverse-Engineering: by default, clients will abort execution if a virtual machine or sandbox is detected Modules Post-exploitation modules that are remotely importable by clients Keylogger (byob.modules.keylogger😞 logs the user’s keystrokes & the window name entered Screenshot (byob.modules.screenshot😞 take a screenshot of current user’s desktop Webcam (byob.modules.webcam😞 view a live stream or capture image/video from the webcam Ransom (byob.modules.ransom😞 encrypt files & generate random BTC wallet for ransom payment Outlook (byob.modules.outlook😞 read/search/upload emails from the local Outlook client Packet Sniffer (byob.modules.packetsniffer😞 run a packet sniffer on the host network & upload .pcap file Persistence (byob.modules.persistence😞 establish persistence on the host machine using 5 different methods Phone (byob.modules.phone😞 read/search/upload text messages from the client smartphone Escalate Privileges (byob.modules.escalate😞 attempt UAC bypass to gain unauthorized administrator privileges Port Scanner (byob.modules.portscanner😞 scan the local network for other online devices & open ports Process Control (byob.modules.process😞 list/search/kill/monitor currently running processes on the host iCloud (byob.modules.icloud😞 check for logged in iCloud account on macOS Spreader (byob.modules.spreader😞 spread client to other hosts via emails disguised as a plugin update Miner (byob.modules.miner😞 run a cryptocurrency miner in the background (supports Bitcoin & Litecoin) Server Command & control server with persistent database and console Console-Based User-Interface: streamlined console interface for controlling client host machines remotely via reverse TCP shells which provide direct terminal access to the client host machines Persistent SQLite Database: lightweight database that stores identifying information about client host machines, allowing reverse TCP shell sessions to persist through disconnections of arbitrary duration and enabling long-term reconnaissance Client-Server Architecture: all python packages/modules installed locally are automatically made available for clients to remotely import without writing them to the disk of the target machines, allowing clients to use modules which require packages not installed on the target machines Core Core framework modules used by the generator and the server Utilities (byob.core.util😞 miscellaneous utility functions that are used by many modules Security (byob.core.security😞 Diffie-Hellman IKE & 3 encryption modes (AES-256-OCB, AES-256-CBC, XOR-128) Loaders (byob.core.loaders😞 remotely import any package/module/scripts from the server Payloads (byob.core.payloads😞 reverse TCP shell designed to remotely import dependencies, packages & modules Stagers (byob.core.stagers😞 generate unique payload stagers to prevent analysis & detection Generators (byob.core.generators😞 functions which all dynamically generate code for the client generator Database (byob.core.database😞 handles interaction between command & control server and the SQLite database Handler (byob.core.handler😞 HTTP POST request handler for remote file uploads to the server To Do Contributors welcome! Feel free to issue pull-requests with any new features or improvements you have come up with! Remote Import Encryption - encryption for data streams of packages/modules being remotely imported (to maintain confidentiality/authenticity/integrity and prevent any remote code execution vulnerabilities arising from deserialization) Transport Types - add support for more transport types (HTTP/S, DNS, etc.) Bug Fixes - fix any bugs/issues Download: [HIDE][Hidden Content]]
