Procedure Examples

Name Description

Aria-body has the ability to identify the titles of running windows on a compromised host.[1]


Attor can obtain application window titles and then determines which windows to perform Screen Capture on.[2]


Cadelspy has the ability to identify open windows on the compromised host.[3]


Catchamas obtains application windows titles and then determines which windows to perform Screen Capture on.[4]


The discovery modules used with Duqu can collect information on open windows.[5]


HotCroissant has the ability to list the names of all open windows on the infected host.[6]


InvisiMole can enumerate windows and child windows on a compromised host.[7][8]


Kazuar gathers information about opened windows.[9]

Lazarus Group

Lazarus Group malware IndiaIndia obtains and sends to its C2 server the title of the window for each running process. The KilaAlfa keylogger also reports the title of the window in the foreground.[10][11][12]


Machete saves the window names.[13]


Metamorfo can enumerate all windows on the victim’s machine.[14][15]


NetTraveler reports window names along with keylogger information to provide application context.[16]


njRAT gathers information about opened windows during the initial infection.[17]


PLEAD has the ability to list open windows on the compromised host.[18]


PoisonIvy captures window titles.[19]


PowerDuke has a command to get text of the current foreground window.[20]


Remexi has a command to capture active windows on the machine and retrieve window titles.[21]


SOUNDBITE is capable of enumerating application windows.[22]


Trojan.Karagany can monitor the titles of open windows to identify specific keywords.[23]


WINERACK can enumerate active windows.[24]


This type of attack technique cannot be easily mitigated with preventive controls since it is based on the abuse of system features.


System and network discovery techniques normally occur throughout an operation as an adversary learns the environment. Data and events should not be viewed in isolation, but as part of a chain of behavior that could lead to other activities based on the information obtained.

Monitor processes and command-line arguments for actions that could be taken to gather system and network information. Remote access tools with built-in features may interact directly with the Windows API to gather information. Information may also be acquired through Windows system management tools such as Windows Management Instrumentation and PowerShell.
