Adversaries may abuse Lua commands and scripts for execution. Lua is a cross-platform scripting and programming language primarily designed for embedded use in applications. Lua can be executed on the command-line (through the stand-alone lua interpreter), via scripts (.lua), or from Lua-embedded programs (through the struct lua_State).^[1],[2]

Lua scripts may be executed by adversaries for malicious purposes. Adversaries may incorporate, abuse, or replace existing Lua interpreters to allow for malicious Lua command execution at runtime.^{[3],[4],[5],[6]}
