BruteShark v1.2.5

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.

What it can do
Extracting and encoding usernames and passwords (HTTP, FTP, Telnet, IMAP, SMTP...)
Extract authentication hashes and crack them using Hashcat (Kerberos, NTLM, CRAM-MD5, HTTP-Digest...)
Build visual network diagram (Network nodes & users)
Reconstruct all TCP & UDP Sessions
File Carving

Windows Prerequisites:
WinPcap / Npcap driver (Wireshark installs one of this by default)

Linux Prerequisites:
libpcap driver

Brute Shark CLI


All BruteShark projects are implemented using .Net Core and .Net Standard for modern and cross platform support. 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 their wrapper library SharpPcap. 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))

// 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()

_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));


BruteSharkCLI (PL)

(1). help
(2). add-file
(3). start
(4). show-passwords
(5). show-hashes
(6). export-hashes
