A Cobalt Strike Beacon Object File (BOF) project which uses direct system calls to enumerate processes for specific modules or process handles. What is this repository for? Use direct systems calls within Beacon Object files to enumerate processes for specific loaded modules (e.g. winhttp.dll, amsi.dll or clr.dll). Use direct systems calls within Beacon Object filesRead More
aggrokatz is an Aggressor plugin extension for CobaltStrike which enables pypykatz to interface with the beacons remotely. The current version of aggrokatz allows pypykatz to parse LSASS dump files and Registry hive files to extract credentials and other secrets stored without downloading the file and without uploading any suspicious code to the beacon (Cobalt StrikeRead More
Movekit is an extension of built in Cobalt Strike lateral movement by leveraging the execute_assembly function with the SharpMove and SharpRDP .NET assemblies. The aggressor script handles payload creation by reading the template files for a specific execution type. IMPORTANT: To use the script a user will only need to load the MoveKit.cna aggressor scriptRead More
AzureC2Relay is an Azure Function that validates and relays Cobalt Strike beacon traffic by verifying the incoming requests based on a Cobalt Strike Malleable C2 profile. Any incoming requests that do not share the profiles user-agent, URI paths, headers, and query parameters, will be redirected to a configurable decoy website. The validated C2 traffic isRead More
PyBeacon is a collection of scripts for dealing with Cobalt Strike’s encrypted traffic. It can encrypt/decrypt beacon metadata, as well as parse symmetric encrypted taskings Scripts included There is a small library which includes encryption/decoding methods, however some example scripts are included. stager-decode.py – this tool will simply decode a beacon DLL from a stagerRead More
A Proof of Concept Cobalt Strike Beacon Object File which uses direct system calls to enable WDigest credential caching and circumvent Credential Guard (if enabled). Additional guidance can be found in this blog post: https://outflank.nl/blog/?p=1592 Background This PoC code is based on the following excellent blog posts: Exploring Mimikatz – Part 1 – WDigest BypassingRead More
Adds Shellcode – Shellcode Generator to the Cobalt Strike top menu bar CSSG is an aggressor and python script used to more easily generate and format beacon shellcode Generates beacon stageless shellcode with exposed exit method, additional formatting, encryption, encoding, compression, multiline output, etc shellcode transforms are generally performed in descending menu order Requirements: TheRead More
