SMBeagle
*** We now run on Linux!!! ***
Intro
SMBeagle is an (SMB) fileshare auditing tool that hunts out all files it can see in the network and reports if the file can be read and/or written. All these findings are streamed out to either a CSV file or an elasticsearch host, or both!? 🚀
SMBeagle tries to make use of the win32 APIs for maximum speed, but fails back to a slower ACL check.
It has 2 awesome use cases:
Cast a spotlight on weak share permissions.
Businesses of all sizes often have file shares with awful file permissions.
Large businesses have sprawling shares on file servers and its not uncommon to find sensitive data with misconfigured permissions.
Small businesses often have a small NAS in the corner of the office with no restrictions at all!
SMBeagle crawls these shares and lists out all the files it can read and write. If it can read them, so can ransomware.
Lateral movement and privilege escalation
SMBeagle can provide penetration testers with the less obvious routes to escalate privileges and move laterally.
By outputting directly into elasticsearch, testers can quickly find readable scripts and writeable executables.
Finding watering hole attacks and unprotected passwords never felt so easy! 🐱👤

Installation
Go to the latest release on the right-hand side of the repo >>>>
Download the win_x64.zip (only 64bit is supported at the moment)
Unzip the download and run SMBeagle.exe from a command prompt or powershell terminal
Usage
The only mandatory parameter is to set an output, which should be either an elasticsearch hosts IP address or a csv file.
A good starting point is to enable fast mode and output to csv, but this CSV could get huge depending on how many files it finds.
Public IP scanning
The scanning of discovered public hosts and networks is disabled by default as SMBeagle discovers networks from netstat which includes all current connections such as web browser sessions etc.
To scan a public network, declare it manually with something like -n 1.0.0.1/32 or -n 1.0.0.0/24
Docker usage
Punk security provides a linux docker image of SMBeagle.
Run SMBeagle: docker run -v "./output:/tmp/output" punksecurity/smbeagle -c /tmp/output/results.csv -n 10.10.10.0/24 Note that network discovery is disabled when running in docker, so make sure you pass the ranges that you wish to scan with the -n command line switch.

Architecture
SMBeagle does a lot of work, which is broken down into loosely coupled modules which hand off to each other. This keeps the design simple and allows us to extend each module easily.
