nullinux's Introduction

nullinux

Nullinux is an internal penetration testing tool for Linux that can be used to enumerate OS information, domain information, shares, directories, and users through SMB. If no username and password are provided in the command line arguments, an anonymous login, or null session, is attempted. Nullinux acts as a wrapper around the Samba tools smbclient & rpcclient to enumerate hosts using a variety of techniques.

Key Features:

Single or multi-host enumeration
Enumerate shares and list files in root directory
Enumerate users & groups
Multi-threaded RID Cycling
Creates a formatted nullinux_users.txt output file free of duplicates for further exploitation
Python 2.7 & 3 compatible
