Nytro Posted January 25, 2021 Report Posted January 25, 2021 About What it can do Download Examples Usage Modules BruteSharkDesktop BruteSharkCli Architecture Contributing About BruteShark is a Network Forensic Analysis Tool (NFAT) that performs deep processing and inspection of network traffic (mainly PCAP files). It includes: password extracting, building a network map, reconstruct TCP sessions, extract hashes of encrypted passwords and even convert them to a Hashcat format in order to perform an offline Brute Force attack. The main goal of the project is to provide solution to security researchers and network administrators with the task of network traffic analysis while they try to identify weaknesses that can be used by a potential attacker to gain access to critical points on the network. Two BruteShark versions are available, A GUI based application (Windows) and a Command Line Interface tool (Windows and Linux). The various projects in the solution can also be used independently as infrastructure for analyzing network traffic on Linux or Windows machines. For further details see the Architecture section. The project was developed in my spare time to address two main passions of mine: software architecture and analyzing network data. I love to get feedbacks from BruteShark users, your opinion is important to me! Feel free to contact me on contact.oded.shimon@gmail.com or create new issue.

Windows 10 user NTLM password Run Brute Shark CLI on Ubuntu with Mono Hashes Extracting Building a Network Diagram File Carving Password Extracting Reconstruct all TCP Sessions Brute Shark CLI Usage In general, it is recommended to use the example PCAP files folder, load, run and explore the results. Modules BruteShark is a modular tool, designed for expansion. Credentials Module This module is responsible for extracting and encoding usernames and passwords as well as authentication hashes. In fact this module is responsible for updating two display tables, passwords table and hashes table. While usernames and passwords are straight forward to use, hashes most often used in more complex attacks like pass-the-hash or by brute-forcing them to get the password. BruteShark is integrated with Hashcat so all the hashes extracted can be converted to a Hashcat input file. Protocol Hash Type Hascat Mode (-m) HTTP HTTP-Digest 11400 SMTP\IMAP CRAM-MD5 16400 NTLM (e.g. SMB) NTLMv1 5500 NTLM (e.g. SMB) NTLMv2 5600 Kerberos AS-REQ etype 23 7500 Kerberos TGS-REP etype 23 13100 Kerberos AS-REP etype 23 18200 Network Map Module This module is responsible for building the network map by identifying components in the network and the connections between them. The network map can be exported to JSON format for analysis with external tools such as Neo4j. Files Extracting Module This module tries to extract files from UDP / TCP sessions (Therefore, note that in order for this module to be effective, the "Build TCP Sessions" / "Build UDP Sessions" should be turn on). Currently this module supports classic forensics techniques of file carving by "Header-Footer" algorithm which is effective for files with known file header and footer like JPG, PNG, PDF. BruteSharkDesktop The GUI is pretty self-explanatory, just load the wanted files, configure the wanted modules and press the run button. BruteSharkCli BruteSharkCli has two modes: single command and shell mode. The single command mode works by geting all the relevant parameters for the processing and then printing the results to stdout or files. The shell mode allows to perform each step individually. Single Command Mode Print the help menu: C:\Users\King\Desktop\BruteSharkCli>BruteSharkCli.exe --help BruteSharkCli 1.0.0.0 Copyright c 2018 -d, --input-dir The input directory containing the files to be processed. -i, --input The files to be processed seperated by comma -m, --modules The modules to be separterd by comma: Credentials, FileExtracting, NetworkMap -o, --output Output direcorty for the results files. --help Display this help screen. --version Display version information.

The solution is designed with three layer architecture, including a one or more projects at each layer - DAL, BLL and PL. The separation between layers is created by the fact that each project refers only its own objects. PcapProcessor (DAL) As the Data Access Layer, this project is responsible for reading raw PCAP files using appropriate drivers (WinPcap, libpcap) and the amazing wrapper library SharpPcap by Chris Morgan. Can analyze a list of files at once, and provides additional features like reconstruction of all TCP Sessions (using the awesome project TcpRecon). PcapAnalyzer (BLL) The Business Logic Layer, responsible for analyzing network information (packet, TCP Session etc.), implements a pluggable mechanism. Each plugin is basically a class that implements the interface IModule. All plugins are loaded using reflection: private void _initilyzeModulesList() { // Create an instance for any available modules by looking for every class that // implements IModule. this._modules = AppDomain.CurrentDomain.GetAssemblies() .SelectMany(s => s.GetTypes()) .Where(p => typeof(IModule).IsAssignableFrom(p) && !p.IsInterface) .Select(t => (IModule)Activator.CreateInstance(t)) .ToList(); // Register to each module event. foreach(var m in _modules) { m.ParsedItemDetected += (s, e) => this.ParsedItemDetected(s, e); } } BruteSharkDesktop (PL) Desktop application for Windows based on WinForms. Uses a cross-cutting project by the meaning it referrers both the DAL and BLL layers. This is done by composing each of the layers, register to their events, when event is triggered, cast the event object to the next layer equivalent object, and send it to next layer. public MainForm() { InitializeComponent(); _files = new HashSet<string>(); // Create the DAL and BLL objects. _processor = new PcapProcessor.Processor(); _analyzer = new PcapAnalyzer.Analyzer(); _processor.BuildTcpSessions = true; // Create the user controls. _networkMapUserControl = new NetworkMapUserControl(); _networkMapUserControl.Dock = DockStyle.Fill; _sessionsExplorerUserControl = new SessionsExplorerUserControl(); _sessionsExplorerUserControl.Dock = DockStyle.Fill; _hashesUserControl = new HashesUserControl(); _hashesUserControl.Dock = DockStyle.Fill; _passwordsUserControl = new GenericTableUserControl(); _passwordsUserControl.Dock = DockStyle.Fill; // Contract the events. _processor.TcpPacketArived += (s, e) => _analyzer.Analyze(Casting.CastProcessorTcpPacketToAnalyzerTcpPacket(e.Packet)); _processor.TcpSessionArived += (s, e) => _analyzer.Analyze(Casting.CastProcessorTcpSessionToAnalyzerTcpSession(e.TcpSession)); _processor.FileProcessingStarted += (s, e) => SwitchToMainThreadContext(() => OnFileProcessStart(s, e)); _processor.FileProcessingEnded += (s, e) => SwitchToMainThreadContext(() => OnFileProcessEnd(s, e)); _processor.ProcessingPrecentsChanged += (s, e) => SwitchToMainThreadContext(() => OnProcessingPrecentsChanged(s, e)); _analyzer.ParsedItemDetected += (s, e) => SwitchToMainThreadContext(() => OnParsedItemDetected(s, e)); _processor.TcpSessionArived += (s, e) => SwitchToMainThreadContext(() => OnSessionArived(Casting.CastProcessorTcpSessionToBruteSharkDesktopTcpSession(e.TcpSession))); _processor.ProcessingFinished += (s, e) => SwitchToMainThreadContext(() => OnProcessingFinished(s, e)); InitilizeFilesIconsList(); this.modulesTreeView.ExpandAll(); } Contributing First off, thanks for taking the time to contribute!
