T1027.008 Stripped Payloads

Sub-technique of: T1027

High-Level Description

Adversaries may attempt to make a payload difficult to analyze by removing symbols, strings, and other human readable information. Scripts and executables may contain variables names and other strings that help developers document code functionality. Symbols are often created by an operating system’s linker when executable payloads are compiled. Reverse engineers use these symbols and strings to analyze code and to identify functionality in payloads.

Adversaries may use stripped payloads in order to make malware analysis more difficult. For example, compilers and other tools may provide features to remove or obfuscate strings and symbols. Adversaries have also used stripped payload formats, such as run-only AppleScripts, a compiled and stripped version of AppleScript, to evade detection and analysis. The lack of human-readable information may directly hinder detection and analysis of payloads.

Kill Chain Phase

Defense Evasion (TA0005)

Platforms: macOS, Linux, Windows, Network Devices

What to Check

Identify if Stripped Payloads technique is applicable to target environment
Check macOS systems for indicators of Stripped Payloads
Check Linux systems for indicators of Stripped Payloads
Check Windows systems for indicators of Stripped Payloads
Assess detection coverage (1 detection strategies)

How to Test

Manual Testing

Identify Attack Surface: Determine if the target environment is susceptible to Stripped Payloads by examining the target platforms (macOS, Linux, Windows).
Assess Existing Defenses: Review whether mitigations for T1027.008 are in place. If defenses are absent or misconfigured, this technique may be exploitable.
Execute Test: Use tools and methods described in the MITRE ATT&CK page and external references below.

Note: No Atomic Red Team tests available for this technique. See Atomic Red Team GitHub for updates.

Remediation Guide
