Непрямое выполнение команд

Adversaries may abuse utilities that allow for command execution to bypass security restrictions that limit the use of command-line interpreters. Various Windows utilities may be used to execute commands, possibly without invoking cmd. For example, Forfiles, the Program Compatibility Assistant (`pcalua.exe`), components of the Windows Subsystem for Linux (WSL), `Scriptrunner.exe`, as well as other utilities may invoke the execution of programs and commands from a Command and Scripting Interpreter, Run window, or via scripts.(Citation: VectorSec ForFiles Aug 2017)(Citation: Evi1cg Forfiles Nov 2017)(Citation: Secure Team - Scriptrunner.exe)(Citation: SS64)(Citation: Bleeping Computer - Scriptrunner.exe) Adversaries may also abuse the `ssh.exe` binary to execute malicious commands via the `ProxyCommand` and `LocalCommand` options, which can be invoked via the `-o` flag or by modifying the SSH config file.(Citation: Threat Actor Targets the Manufacturing industry with Lumma Stealer and Amadey Bot) Adversaries may abuse these features for Defense Evasion, specifically to perform arbitrary execution while subverting detections and/or mitigation controls (such as Group Policy) that limit/prevent the usage of cmd or file extensions more commonly associated with malicious payloads.

Forfiles can be used to subvert controls and possibly conceal command execution by not directly invoking cmd.(Citation: VectorSec ForFiles Aug 2017)(Citation: Evi1cg Forfiles Nov 2017)
Revenge RAT

Revenge RAT uses the Forfiles utility to execute commands on the system.(Citation: Cofense RevengeRAT Feb 2019)
Lazarus Group

Lazarus Group persistence mechanisms have used forfiles.exe to execute .htm files.(Citation: Qualys LolZarus)

Indirect Command Execution Mitigation

Identify or block potentially malicious software that may contain abusive functionality by using whitelisting (Citation: Beechey 2010) tools, like AppLocker, (Citation: Windows Commands JPCERT) (Citation: NSA MS AppLocker) or Software Restriction Policies (Citation: Corio 2008) where appropriate. (Citation: TechNet Applocker vs SRP). These mechanisms can also be used to disable and/or limit user access to Windows utilities and file types/locations used to invoke malicious execution.(Citation: SpectorOPs SettingContent-ms Jun 2018)

Обнаружение

Monitor and analyze logs from host-based detection mechanisms, such as Sysmon, for events such as process creations that include or are resulting from parameters associated with invoking programs/commands/files and/or spawning child processes/network connections. (Citation: RSA Forfiles Aug 2017)
