# Living Off The Land Binaries and Scripts (and now also Libraries)

<img src="https://github.com/api0cradle/LOLBAS/raw/master/Logo/LOLBAS.png" height="250">

All the different files can be found behind a fancy frontend here: https://lolbas-project.github.io (thanks @ConsciousHacker for this bit of eyecandy and the team over at https://gtfobins.github.io/).
This repo serves as a place where we maintain the YML files that are used by the fancy frontend.

## Goal

The goal of the LOLBAS project is to document every binary, script, and library that can be used for Living Off The Land techniques.

## Criteria

A LOLBin/Lib/Script must:

* Be a Microsoft-signed file, either native to the OS or downloaded from Microsoft.
* Have extra "unexpected" functionality. It is not interesting to document intended use cases.
  * Exceptions are application whitelisting bypasses
* Have functionality that would be useful to an APT or red team

Interesting functionality can include:

* Executing code
  * Arbitrary code execution
  * Pass-through execution of other programs (unsigned) or scripts (via a LOLBin)
* Compiling code
* File operations
  * Downloading
  * Upload
  * Copy
* Persistence
  * Pass-through persistence utilizing existing LOLBin
  * Persistence (e.g. hide data in ADS, execute at logon)
* UAC bypass
* Credential theft
* Dumping process memory
* Surveillance (e.g. keylogger, network trace)
* Log evasion/modification
* DLL side-loading/hijacking without being relocated elsewhere in the filesystem.

## Contributing

If you have found a new LOLBin or LOLScript that you would like to contribute, please review the contributing guidelines located here: https://github.com/LOLBAS-Project/LOLBAS/blob/master/CONTRIBUTING.md

A template for the required format has been provided here: https://github.com/LOLBAS-Project/LOLBAS/blob/master/YML-Template.yml

## The History of the LOLBin

The phrase "Living off the land" was coined by Christopher Campbell (@obscuresec) & Matt Graeber (@mattifestation) at [DerbyCon 3](https://www.youtube.com/watch?v=j-r6UonEkUw).

The term LOLBins came from a Twitter discussion on what to call binaries that can be used by an attacker to perform actions beyond their original purpose. Philip Goh (@MathCasualty) [proposed LOLBins](https://twitter.com/MathCasualty/status/969174982579273728). A highly scientific internet poll ensued, and after a general consensus (69%) was reached, the name was [made official](https://twitter.com/Oddvarmoe/status/985432848961343488). Jimmy (@bohops) [followed up with LOLScripts](https://twitter.com/bohops/status/984828803120881665). No poll was taken.

Common hashtags for these files are:

* #LOLBin
* #LOLBins
* #LOLScript
* #LOLScripts
* #LOLLib
* #LOLLibs

Our primary maintainer (@oddvarmoe) of this project did a talk at DerbyCon 2018 called: #Lolbins Nothing to LOL about! - https://www.youtube.com/watch?v=NiYTdmZ8GR4
This talk goes over the history of this project.
