Osmedeus Next Generation - A Workflow Engine for Offensive Security

Overview

j3ssie/osmedeus

Understand the workflow¶

Workflow is the core of the Osmedeus Engine which represents your methodology as YAML files.

routine-detail

All Workflow files are YAML-based so make sure you follow the YAML syntax. Otherwise, it wouldn't work

Module contains detail of multiple step.
Flow contains multiple module and also define order how to run these modules.
Step is smallest part of the Osmedeus routine.

Example Flow¶

General flow¶

name: general
desc: run normal routine
type: general # this is a folder name that will contains module file
validator: domain # validate the input provide from -t option

routines:
  - modules:
      - subdomain
  - modules:
      - probing
  - modules:
      - ssame
  - modules:
      - screenshot
  - modules: # these modules will be run in parallel
      - fingerprint
      - spider
      - sto
  - modules:  # these modules will be run in parallel
      - archive
      - ipspace
  - modules:
      - vulnscan
  - modules:
      - vhostscan
  - modules:
      - portscan
  - modules:
      - pdirbscan
  - modules:
      - dirbscan
  # push final result again
  - modules:
      - summary

Step¶

Here are three different steps for running commands and scripts.

Normal Step¶

steps: # all the steps will run in serial
  - commands: # unix command and it will be run in parallel
      - "unix command 1 here"
      - "unix command 2 here"
    scripts: 
      - ExecCmd("unix command 3 heret") # command 3 and 4 below it will be run in serial
      - ExecCmd("unix command 4 here")
      - SortU("filename-here.txt")

Step with conditions¶

steps: # all the steps will run in serial
  - required: # Check if all the files exist or the step will not run
      - filename-1-here.txt
    conditions: # Boolean conditions check with built-in scripts
      - "FileLength('filename.txt') > 10000"
      - Exit(1) # this will exit the module imeediately
    commands: # unix command and it will be run in parallel
      - "unix command 1 here"
      - "unix command 2 here"
    scripts: 
      - ExecCmd("unix command 3 heret") # command 3 and 4 below it will be run in serial
      - ExecCmd("unix command 4 here")
      - SortU("filename-here.txt")
      - TeleMessByFile("#dirb", "beautify-{{Workspace}}.txt")

- required: # Check if all the files exist or the step will not run
      - filename-2-here.txt
    conditions: # Boolean conditions check with built-in scripts
      - "FileLength('filename-2-here.txt') > 10000"
    ## only run if conditions is false
    rcommands: # run in parallel
      - "unix command 1 here"
      - "unix command 2 here"
    rscripts:
      - ErrPrintf("Filter", "Got input file greater than 1000 line")
      - Exit(1) # this will exit the module imeediately

Step with the loop using `source:` tag and `[[.line]]` variable.¶

steps:
 # variation 2 that will run the step but with input is each like of 'source' section
  - source: "{{inputFile}}" # source file to loop through
    threads: '{{dirbThreads}}'
    commands: # {{Binaries}} is the path to binaries which usually ~/osmedeus/binaries/ but you can use any tool inside your $PATH environment variable
      - "{{Binaries}}/ffuf-mod -H 'X-Forwarded-For: 127.0.0.1' -t {{fthreads}} -recursion-depth {{recursion}} -D -e 'asp,aspx,php,html,htm,jsp,cgi' -timeout 15 -get-hash -ac -s -fc '429,404,400' -of json -o {{Output}}/directory/raw-[[._id_]].json -u '[[.line]]/FUZZ' -w {{wordlists}}:FUZZ"
    scripts:
      - SortU("{{Storages}}/paths/{{Workspace}}/paths-{{Workspace}}.csv")
