rbkb

DESCRIPTION:

Ruby BlackBag (rbkb)

A miscellaneous collection of command-line tools and ruby library helpers related to pen-testing and reversing.

Rationale

Disclaimer: 
Most of what's in the black bag came from a desire to do less typing.
But there might be a few clever things that were added by accident.

rbkb is inspired by Matasano BlackBag (a set of similar tools written in C).

See: blackbag - github.com/emonti/rbkb/raw/master/reference/blackbag-0.9.1.tgz

Things go into the black bag as they are stolen (as a compliment!) or dreamed up, usually for simplifying some repetetive task or a desire for a new tool.

Along the way, some of tools in the blackbag spirit make their way into 'rbkb' that may or may not make it to 'bkb' right away (if ever). Similarly some of the things in 'bkb' have not yet made it to 'rbkb' (and may not).

SYNOPSIS:

Command Line Tools

The tools almost all support '-h', but I'll admit this only goes so far. See cli_usage.rdoc for usage and a bit of extra info on the various tools.

When I get some spare time, I'll try and do up some examples of using all the tools.

Plug

Black Bag includes several tools for testing network protocols using plugboard proxies. Users of the original Matasano BlackBag may be familiar with the commands 'bkb replug', 'bkb telson', and 'bkb blit'.

Ruby BlackBag has a similar set of network tools:

  • 'blit' : Uses a simple homegrown OOB IPC mechanism (local socket) to communicate with 'blit-capable' tools like telson and plugsrv and send data to network endpoints through them. Use 'blit' to send raw messages to servers or clients then watch how they respond (see below).

  • 'telson' : Similar to 'bkb telson'. Opens a TCP or UDP client connection which is little more than a receiver for 'blit' messages. Use this to pretend to be a client and send raw messages to some service while observing raw replies.

  • 'plugsrv' : Similar to 'bkb replug'. Sits as a reverse TCP proxy between one or more clients and a server. Accepts 'blit' messages which can be directed at client or server ends of a conversation. The original 'replug' didn't do this, which makes plugsrv kindof neat.

Monkey Patches

Much of rbkb is implemented as a bunch of monkeypatches to Array, String, Numeric and other base classes. If this suits your fancy (some people despise monkeypatches, this is not their fancy) then you can 'require “rbkb”' from your irb sessions and own scripts. See 'lib_usage.rdoc' for more info.

REQUIREMENTS:

  • eventmachine >= 0.12.8

INSTALL:

Gem Installation

rbkb is available as a gem on gemcutter.org:

gem install rbkb --source http://gemcutter.org

Gem Install Note

Installing the gem as root may be risky depending on your rubygems configuration so I don't really recommend using 'sudo gem install'. Worst case scenario I know of is I blew away my OSX-shipped '/usr/bin/crc32' this way. It was written in perl, so I considered this providence and didn't look back. But you may feel differently about 'rubygems' clobbering a file in /usr/bin.

When installing as a regular user, however, rubygems may stick rbkb's executable bin/* files somewhere unexpected. To find out where these are and either add them to your PATH or copy/symlink them somewhere else like /usr/local/bin/ do this:

gem contents rbkb

Manual installation:

git clone git://github.com/emonti/rbkb.git
cd rbkb
rake gem:install

or … you can also install manually without rubygems.

You can access the rbkb project at github. You'll want git installed:

cp -r rbkb/lib/* /usr/lib/ruby/1.8/site_ruby/1.8 # or another ruby libdir
cp bin/* ~/bin      # or wherever else in your PATH

Run this to generate docs with rdoc the same way the gem would have:

rake doc:rdoc
