# Situational Awareness BOF

This repo intends to serve two purposes.  First it provides a nice set of basic situational awareness commands implemented in a Beacon Object File (BOF).  This allows you to perform some checks on a host before you begin executing commands that may be more invasive.



Its larger goal is providing a code example and workflow for others to begin making more BOFs. It is a companion document of the blog post made here: https://www.trustedsec.com/blog/a-developers-introduction-to-beacon-object-files/



## Making a new BOF

If you want to use the same workflow as this repository, your basic steps are as follows:

1. Make a folder that covers the target topic, for example in this repo we are using SA

2. Copy the base_template into topic/commandname

3. Modify the Makefile to have your commandname on the first line. This should be the same as the folder name

4. If doing something other then SA, make sure to modify lines 14 and 15 of the makefile as well so its moved to the correct location

5. Make a .cna file in the base of your topic folder and add the commands that you reference. If you followed this format you can take the helper function readbof from SA.cna



Realistically, this could be compressed into a helper script, but those steps were not taken for this effort.



## Available commands

|Commands|Usage|Notes|

|--------|-----|-----|

|adcs_enum | adcs_enum| Enumerate CAs and templates in the AD using Win32 functions|

|netsession| netsession [opt:computer]| Enumerate sessions on the local or specified computer|

|netsession2| netsession2 [opt:computer] [opt:resolution method] [opt:dns server]| Modified version of `netsession` that supports BOFHound|

|netshares| netshares [hostname]| List shares on the local or remote computer|

|netstat| netstat| TCP and UDP IPv4 listing ports|

|nettime| nettime [hostname]| Display time on remote computer|

|netuptime| netuptime [hostname]| Return information about the boot time on the local or remote computer|

|netuser| netuser [username] [opt: domain]| Get info about specific user. Pull from domain if a domainname is specified|

|netuse_add| netuse_add [sharename] [opt:username] [opt:password] [opt:/DEVICE:devicename] [opt:/PERSIST] [opt:/REQUIREPRIVACY]| Bind a new connection to a remote computer|

|netuse_delete| netuse_delete [device\|\|sharename] [opt:/PERSIST] [opt:/FORCE]| Delete the bound device / sharename]|

|netuse_list| netuse_list [opt:target]| List all bound share resources or info about target local resource|

|netview| netview| List reachable computers in the current domain|

|nslookup| nslookup [hostname] [opt:dns server] [opt: record type]| Make a DNS query.

|wmi_query| wmi_query query [opt: server] [opt: namespace]| Run a wmi query and display results in CSV format|



Note the reason for including reg_query when CS has a built in reg query(v) command is because this one can target remote computers and has the ability to recursively enumerate a whole key.



#### Credits

The functional code for most of these commands was taken from the reactos project or code examples hosted on MSDN.

The driversigs codebase comes from https://gist.github.com/jthuraisamy/4c4c751df09f83d3620013f5d370d3b9



Thanks all of the contributors listed under contributors. Each of you have contributed something meaningful to this repository and dealt with me and my review processes. I appreciate each and every one of you for teaching me and helping make this BOF repository the best it can be!



##### Compiler used

Precompiled BOF's are provided in this project and are compiled using a recent version of Mingw-w64 typically installed from Brew.



## System Support

These BOF's are written with support for Windows Vista+ in mind. A new branch called [winxp_2003](https://github.com/trustedsec/CS-Situational-Awareness-BOF/tree/winxp_2003) has been created if you need to use the main set of BOF's on those older systems. This branch will remain in a less supported state. It will be functional, but not updated with every new push / feature that we may add.
