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

There are currently three different lists.

• LOLBins
• LOLLibs
• LOLScripts

Goal

The goal of the LOLBAS project are to document every binary, script and library that can be used for Living Off The Land techniques.
Primarily files that offer "extra" functionality.

Definition

• Must be a Microsoft signed file. (Native to the OS or downloaded from Microsoft site)

• Only extra "unexpected" functionality is interesting (Not interesting to document what it was intended for)

  • Exceptions are Application Whitelisting bypasses

• Primary focus is stuff that can be leveraged by APT or in Red Teaming

• Functionality can include:

  • Executing code
    • Arbitrary code execution
    • Pass-through execution of other programs (unsigned), script (via a LOLBin)
  • Compile code
  • File operations
    • downloading
    • upload
    • copy
  • Persistence
    • pass-through persistence utilizing existing LOLBin
    • persistence (Hide data in ADS, execute at logon etc)
  • UAC bypass
  • Credentials
  • Dumping process
  • Surveillance (keylogger, network trace)
  • Evade logging/remove log entry
  • DLL Side-Loading/Hijacking (Binary must maintain path integrity - e.g. Without copying a binary to another folder that the user controls)

YML

A yml version of every file is located under the yml folder. This is the master for all things LOLBAS. We generate the MD files from this and later it will also be the base for an upcoming webportal.

STORY

"Living off the land" was coined by Christopher Campbell (@obscuresec) & Matt Graeber (@mattifestation)
One of the first "Living Off The Land" talks is this one: https://www.youtube.com/watch?v=j-r6UonEkUw

The term LOLBins came from a twitter discussion on what to call these binaries that can be used by an attacker to perform other actions than what the binary was designed to do. LOLBins was first proposed by Philip Goh (@MathCasualty) here: https://twitter.com/MathCasualty/status/969174982579273728

The term LOLScripts came from Jimmy (@bohops): https://twitter.com/bohops/status/984828803120881665

Common hashtags for these files are:

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

A "highly scientific poll" was also conducted to agree (69% yes) on the name LOLBins. https://twitter.com/Oddvarmoe/status/985432848961343488

(Thanks!) The awesome logos in the logo folder was provided by Adam Nadrowski (@_sup_mane) - Thank you so much man!
