Matching passage: T1059.011 Lua. Tactics: execution. Description: 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 (<code>.lua</code>), or from Lua-embedded programs (through the <code>struct lua_State</code>).(Citation: Lua main page)(Citation: Lua state) 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.(Citation: PoetRat Lua)(Citation: Lua Proofpoint Sunseed)(Citation: Cyphort EvilBunny)(Citation: Kaspersky Lua)
Near-miss passage: T1059.012 Hypervisor CLI. Tactics: execution. Description: Adversaries may abuse hypervisor command line interpreters (CLIs) to execute malicious commands. Hypervisor CLIs typically enable a wide variety of functionality for managing both the hypervisor itself and the guest virtual machines it hosts. For example, on ESXi systems, tools such as `esxcli` and `vim-cmd` allow administrators to configure firewall rules and log forwarding on the hypervisor, list virtual machines, start and stop virtual machines, and more.(Citation: Broadcom ESXCLI Reference)(Citation: Crowdstrike Hypervisor Jackpotting Pt 2 2021)(Citation: LOLESXi) Adversaries may be able to leverage these tools in order to support further actions, such as [File and Directory Discovery](https://attack.mitre.org/techniques/T1083) or [Data Encrypted for Impact](https://attack.mitre.org/techniques/T1486).

Query: intelligence brief on T1001
Matching passage: T1001 Data Obfuscation. Tactics: command and control. Description: Adversaries may obfuscate command and control traffic to make it more difficult to detect.(Citation: Bitdefender FunnyDream Campaign November 2020) Command and control (C2) communications are hidden (but not necessarily encrypted) in an attempt to make the content more difficult to discover or decipher and to make the communication less conspicuous and hide commands from being seen. This encompasses many methods, such as adding junk data to protocol traffic, using steganography, or impersonating legitimate protocols.
Near-miss passage: T1001.001 Junk Data. Tactics: command and control. Description: Adversaries may add junk data to protocols used for command and control to make detection more difficult.(Citation: FireEye SUNBURST Backdoor December 2020) By adding random or meaningless data to the protocols used for command and control, adversaries can prevent trivial methods for decoding, deciphering, or otherwise analyzing the traffic. Examples may include appending/prepending data with junk characters or writing junk characters between significant characters.
