Adversaries may use execution guardrails to constrain execution or actions based on adversary supplied and environment specific conditions that are expected to be present on the target. Guardrails ensure that a payload only executes against an intended target and reduces collateral damage from an adversary’s campaign.(Citation: FireEye Kevin Mandia Guardrails) Values an adversary can provide about a target system or environment to use as guardrails may include specific network share names, attached physical devices, files, joined Active Directory (AD) domains, and local/external IP addresses.(Citation: FireEye Outlook Dec 2019) Guardrails can be used to prevent exposure of capabilities in environments that are not intended to be compromised or operated within. This use of guardrails is distinct from typical Virtualization/Sandbox Evasion. While use of Virtualization/Sandbox Evasion may involve checking for known sandbox values and continuing with execution only if there is no match, the use of guardrails will involve checking for an expected target-specific value and only continuing with execution if there is such a match. Adversaries may identify and block certain user-agents to evade defenses and narrow the scope of their attack to victims and platforms on which it will be most effective. A user-agent self-identifies data such as a user's software application, operating system, vendor, and version. Adversaries may check user-agents for operating system identification and then only serve malware for the exploitable software while ignoring all other operating systems.(Citation: Trellix-Qakbot)

Название	Описание
Примеры процедур
DEADEYE	DEADEYE can ensure it executes only on intended systems by identifying the victim's volume serial number, hostname, and/or DNS domain.(Citation: Mandiant APT41)
CHIMNEYSWEEP	CHIMNEYSWEEP can execute a task which leads to execution if it finds a process name containing “creensaver.”(Citation: Mandiant ROADSWEEP August 2022)
Anchor	Anchor can terminate itself if specific execution flags are not present.(Citation: Cyberreason Anchor December 2019)
BitPaymer	BitPaymer compares file names and paths to a list of excluded names and directory names during encryption.(Citation: Crowdstrike Indrik November 2018)
BPFDoor	BPFDoor creates a zero byte PID file at `/var/run/haldrund.pid`. BPFDoor uses this file to determine if it is already running on a system to ensure only one instance is executing at a time.(Citation: Sandfly BPFDoor 2022)
DarkGate	DarkGate uses per-victim links for hosting malicious archives, such as ZIP files, in services such as SharePoint to prevent other entities from retrieving them.(Citation: Trellix Darkgate 2023)
Raspberry Robin	Raspberry Robin will check for the presence of several security products on victim machines and will avoid UAC bypass mechanisms if they are identified.(Citation: TrendMicro RaspberryRobin 2022) Raspberry Robin can use specific cookie values in HTTP requests to command and control infrastructure to validate that requests for second stage payloads originate from the initial downloader script.(Citation: HP RaspberryRobin 2024)
VaporRage	VaporRage has the ability to check for the presence of a specific DLL and terminate if it is not found.(Citation: MSTIC Nobelium Toolset May 2021)
EnvyScout	EnvyScout can call `window.location.pathname` to ensure that embedded files are being executed from the C: drive, and will terminate if they are not.(Citation: MSTIC Nobelium Toolset May 2021)
Torisma	Torisma is only delivered to a compromised host if the victim's IP address is on an allow-list.(Citation: McAfee Lazarus Nov 2020)
Small Sieve	Small Sieve can only execute correctly if the word `Platypus` is passed to it on the command line.(Citation: NCSC GCHQ Small Sieve Jan 2022)
Stuxnet	Stuxnet checks for specific operating systems on 32-bit machines, Registry keys, and dates for vulnerabilities, and will exit execution if the values are not met.(Citation: Nicolas Falliere, Liam O Murchu, Eric Chien February 2011)
SUNSPOT	SUNSPOT only replaces SolarWinds Orion source code if the MD5 checksums of both the original source code file and backdoored replacement source code match hardcoded values.(Citation: CrowdStrike SUNSPOT Implant January 2021)
Apostle	Apostle's ransomware variant requires that a base64-encoded argument is passed when executed, that is used as the Public Key for subsequent encryption operations. If Apostle is executed without this argument, it automatically runs a self-delete function.(Citation: SentinelOne Agrius 2021)
LunarLoader	LunarLoader can use the DNS domain name of a compromised host to create a decryption key to ensure a malicious payload can only execute against the intended targets.(Citation: ESET Turla Lunar toolset May 2024)
BoomBox	BoomBox can check its current working directory and for the presence of a specific file and terminate if specific values are not found.(Citation: MSTIC Nobelium Toolset May 2021)
NativeZone	NativeZone can check for the presence of KM.EkeyAlmaz1C.dll and will halt execution unless it is in the same directory as the rest of the malware's components.(Citation: MSTIC Nobelium Toolset May 2021)(Citation: SentinelOne NobleBaron June 2021)
ROADSWEEP	ROADSWEEP requires four command line arguments to execute correctly, otherwise it will produce a message box and halt execution.(Citation: Mandiant ROADSWEEP August 2022)(Citation: CISA Iran Albanian Attacks September 2022)(Citation: Microsoft Albanian Government Attacks September 2022)
Gamaredon Group	Gamaredon Group has used geoblocking to limit downloads of the malicious file to specific geographic locations.(Citation: unit42_gamaredon_dec2022)

Do Not Mitigate	This category is to associate techniques that mitigation might increase risk of compromise and therefore mitigation is not recommended.
Environmental Keying Mitigation	This technique likely should not be mitigated with preventative controls because it may protect unintended targets from being compromised. If targeted, efforts should be focused on preventing adversary tools from running earlier in the chain of activity and on identifying subsequent malicious behavior if compromised.

Обнаружение

Detecting the use of guardrails may be difficult depending on the implementation. Monitoring for suspicious processes being spawned that gather a variety of system information or perform other forms of Discovery, especially in a short period of time, may aid in detection.
