Where this stands

One published detection covers this technique. Every one is unverified — no rule on Siemphony has been executed against real telemetry.

What the technique is

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.

What MITRE says you would watch

  • AN1353

    Suspicious enumeration of attached peripherals via WMI, PowerShell, or low-level API calls potentially chained with removable device interactions.

  • AN1354

    Enumeration of USB and other peripheral hardware via udevadm, lshw, or /sys or /proc interfaces in proximity to collection or mounting behavior.

  • AN1355

    Execution of system utilities like 'system_profiler' and 'ioreg' to enumerate hardware components or USB devices, particularly if followed by clipboard, file, or network activity.
