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

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.

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. A highly scientific internet poll ensued, and after a general consensus (69%) was reached, the name was made official. Jimmy (@bohops) followed up with LOLScripts. No poll was taken.

Common hashtags for these files are:
