Peripheral Device Discovery

Adversaries may attempt to gather information about attached peripheral devices and components connected to a computer system. Peripheral devices could include auxiliary resources that support a variety of functionalities such as keyboards, printers, cameras, smart card readers, or removable storage. The information may be used to enhance their awareness of the system and network environment or may be used for further actions.

Procedure Examples

Name Description
ADVSTORESHELL

ADVSTORESHELL can list connected devices.[1]

APT28

APT28 uses a module to receive a notification every time a USB mass storage device is inserted into a victim.[2]

APT37

APT37 has a Bluetooth device harvester, which uses Windows Bluetooth APIs to find information on connected Bluetooth devices. [3]

Attor

Attor has a plugin that collects information about inserted storage devices, modems, and phone devices.[4]

BADNEWS

BADNEWS checks for new hard drives on the victim, such as USB devices, by listening for the WM_DEVICECHANGE window message.[5][6]

BlackEnergy

BlackEnergy can gather very specific information about attached USB devices, to include device instance ID and drive geometry.[7]

Cadelspy

Cadelspy has the ability to steal information about printers and the documents sent to printers.[8]

DustySky

DustySky can detect connected USB devices.[9]

Equation

Equation has used tools with the functionality to search for specific information about the attached hard drive that could be used to identify and overwrite the firmware.[10]

FlawedAmmyy

FlawedAmmyy will attempt to detect if a usable smart card is current inserted into a card reader.[11]

Gamaredon Group

Gamaredon Group tools have contained an application to check performance of USB flash drives. Gamaredon Group has also used malware to scan for removable drives.[12][13]

jRAT

jRAT can map UPnP ports.[14]

Machete

Machete detects the insertion of new devices by listening for the WM_DEVICECHANGE window message.[15]

MoonWind

MoonWind obtains the number of removable drives from the victim.[16]

njRAT

njRAT will attempt to detect if the victim system has a camera during the initial infection. njRAT can also detect any removable drives connected to the system.[17][18]

Prikormka

A module in Prikormka collects information on available printers and disk drives.[19]

Ragnar Locker

Ragnar Locker may attempt to connect to removable drives and mapped network drives.[20]

Ramsay

Ramsay can scan for removable media which may contain documents for collection.[21]

RTM

RTM can obtain a list of smart card readers attached to the victim.[22][23]

T9000

T9000 searches through connected drives for removable storage devices.[24]

TajMahal

TajMahal has the ability to identify connected Apple devices.[25]

Turla

Turla has used fsutil fsinfo drives to list connected drives.[26]

USBferry

USBferry can check for connected USB devices.[27]

USBStealer

USBStealer monitors victims for insertion of removable drives. When dropped onto a second victim, it also enumerates drives connected to the system.[28]

WannaCry

WannaCry contains a thread that will attempt to scan for new attached drives every few seconds. If one is identified, it will encrypt the files on the attached device.[29]

Zebrocy

Zebrocy enumerates information about connected storage devices.[30]

Mitigations

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

Detection

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.
