XSL Script Processing Defense Evasion [Mitre]
Adversaries may bypass application control and obscure execution of code by embedding scripts inside XSL files. Extensible Stylesheet Language (XSL) files are commonly used to describe the processing and rendering of data within XML files. To support complex operations, the XSL standard includes support for embedded scripting in various languages.
Adversaries may abuse this functionality to execute arbitrary files while …
Modify Registry Defense Evasion [Mitre]
Adversaries may interact with the Windows Registry to hide configuration information within Registry keys, remove information as part of cleaning up, or as part of other techniques to aid in persistence and execution.
Access to specific areas of the Registry depends on account permissions, some requiring administrator-level access. The built-in Windows command-line utility Reg may be used for local or …
Access Token Manipulation: SID-History Injection Defense Evasion [Mitre]
Adversaries may use SID-History Injection to escalate privileges and bypass access controls. The Windows security identifier (SID) is a unique value that identifies a user or group account. SIDs are used by Windows security in both security descriptors and access tokens. An account can hold additional SIDs in the SID-History Active Directory attribute, allowing inter-operable account migration between domains (e.g., …
Impair Defenses: Safe Mode Boot Defense Evasion [Mitre]
Adversaries may abuse Windows safe mode to disable endpoint defenses. Safe mode starts up the Windows operating system with a limited set of drivers and services. Third-party security software such as endpoint detection and response (EDR) tools may not start after booting Windows in safe mode. There are two versions of safe mode: Safe Mode and Safe Mode with Networking. …
Process Injection: Process Doppelgänging Defense Evasion [Mitre]
Adversaries may inject malicious code into process via process doppelgänging in order to evade process-based defenses as well as possibly elevate privileges. Process doppelgänging is a method of executing arbitrary code in the address space of a separate live process.
Windows Transactional NTFS (TxF) was introduced in Vista as a method to perform safe file operations. To ensure data integrity, …
System Binary Proxy Execution: Control Panel Defense Evasion [Mitre]
Adversaries may abuse control.exe to proxy execution of malicious payloads. The Windows Control Panel process binary (control.exe) handles execution of Control Panel items, which are utilities that allow users to view and adjust computer settings.
Control Panel items are registered executable (.exe) or Control Panel (.cpl) files, the latter are actually renamed dynamic-link library (.dll) files that export a CPlApplet …
Impair Defenses: Indicator Blocking Defense Evasion [Mitre]
An adversary may attempt to block indicators or events typically captured by sensors from being gathered and analyzed. This could include maliciously redirecting or even disabling host-based sensors, such as Event Tracing for Windows (ETW), by tampering settings that control the collection and flow of event telemetry. These settings may be stored on the system in configuration files and/or in …
Subvert Trust Controls: Mark-of-the-Web Bypass Defense Evasion [Mitre]
Adversaries may abuse specific file formats to subvert Mark-of-the-Web (MOTW) controls. In Windows, when files are downloaded from the Internet, they are tagged with a hidden NTFS Alternate Data Stream (ADS) named Zone.Identifier with a specific value known as the MOTW. Files that are tagged with MOTW are protected and cannot perform certain actions. For example, starting in MS Office …
Indicator Removal: Clear Command History Defense Evasion [Mitre]
In addition to clearing system logs, an adversary may clear the command history of a compromised account to conceal the actions undertaken during an intrusion. Various command interpreters keep track of the commands users type in their terminal so that users can retrace what they've done.
On Windows hosts, PowerShell has two different command history providers: the built-in history and …
Listplanting Process Manipulating
Edit controls are a type of user interface element that allows a user to enter and edit text in a graphical user interface (GUI). They are commonly used in Windows applications and can be embedded directly into a GUI or subclassed as a separate window.
Edit controls can be set to display text in multiline mode, in which case they …
