Adversaries may physically introduce computer accessories, networking hardware, or other computing devices into a system or network that can be used as a vector to gain access. Rather than just connecting and distributing payloads via removable storage (i.e. Replication Through Removable Media), more robust hardware additions can be used to introduce new functionalities and/or features into a system that can then be abused.
Hardware Additions MITRE reference T1200
1 group has been recorded using this technique. Newest first; each entry carries MITRE’s procedure text and a link to the group’s full record. Click a name to filter the rules below.

Offense vs defense T1200
Is defensive coverage keeping up with adversary use? Eight counts, each ranked against all 697 ATT&CK techniques. Attack sits left, defense right, so a shape leaning left means adversaries are better documented here than defenders are equipped. Hover any spoke for its percentile and the share of techniques that have more. The timeline below shows when each side arrived.
How it got here
Adversary activity (campaign spans) over cumulative rule output. Each source is plotted independently from zero, so neither line includes the other. Campaign dates are year-granularity.
Hardware Additions detection strategy DET0069
MITRE names one behaviour worth catching for this technique and breaks it into 3 analytics, one per platform. Each carries the log sources it needs and the fields you tune per environment.
Detect unauthorized or suspicious Hardware Additions (USB/Thunderbolt/Network)
AN0185 · Windows
Chain: (1) a new external device is recognized by Windows (USB/Thunderbolt/PCIe) or a new block device appears; (2) within a short window, the same user/session spawns processes or the OS mounts a new volume; (3) optional follow-on activity such as HID keystroke injection, DMA driver load, or new network interface MAC on DHCP. Correlate Security EID 6416 / Kernel-PnP with sysmon and DHCP/network metadata.
Log sources
The data this analytic draws on. You do not need every component — each one you already collect covers part of it. Each links to its ATT&CK record.
| Data component | Name | Channel |
|---|---|---|
| Module LoadDC0016 | WinEventLog:Sysmon | EventCode=7 |
| Process CreationDC0032 | WinEventLog:Sysmon | EventCode=1 |
| Application Log ContentDC0038 | WinEventLog:Security | EventCode=6416 |
| File CreationDC0039 | WinEventLog:Sysmon | EventCode=11 |
| Drive CreationDC0042 | WinEventLog:System | Kernel-PnP 410/400 device install, disk added |

| Driver LoadDC0079 | WinEventLog:Sysmon | EventCode=6 |
| Network Connection CreationDC0082 | WinEventLog:Sysmon | EventCode=3, 22 |
Tunable fields
MITRE calls these the analytic’s mutable elements: the thresholds and filters you set for your own environment.
| Field | What you tune |
|---|---|
| TrustedDeviceVIDPID | Vendor/Product IDs that are approved (e.g., keyboards, mice). Unknown/rare VID:PID raise risk. |
| ExpectedBusTypes | Allow-listed bus types for server classes (e.g., USB disabled on DCs). |
| TimeWindow | Correlation window between device recognition and follow-on process/mount/network activity (e.g., 10m–60m). |
| TrustedMACs | Known NIC/USB-NIC MAC addresses allowed by policy. |
AN0186 · Linux
Chain: (1) udev / kernel logs show hot-plug (USB/Thunderbolt/PCIe); (2) block device created by udisks/diskarbitration; (3) optional: new network interface or DHCP lease observed. Correlate /var/log/messages|syslog, auditd SYSCALL open/creat on /dev, and DHCP/Zeek.

Tunable fields
MITRE calls these the analytic’s mutable elements: the thresholds and filters you set for your own environment.
| Field | What you tune |
|---|---|
| BlocklistDeviceStrings | Indicators such as 'RubberDucky', 'BadUSB', unfamiliar USB-NIC chipsets. |
| ServerClassesNoUSB | Hosts where any USB attach should alert (DCs, hypervisors). |
| DHCPVlanScopes | Scopes allowed to issue leases for corp endpoints vs. guest/IoT. |
AN0187 · macOS
Chain: (1) unified logs report IOUSBHost/IOThunderbolt device arrival; (2) diskarbitrationd attaches a new volume; (3) optional: config profile manipulation or new network interface MAC obtains a lease. Correlate unifiedlogs (subsystems: IOUSBHost, IOKit, diskarbitrationd), FSEvents, and DHCP/Zeek.

Establish network access control policies, such as using device certificates and the 802.1x standard. Restrict use of DHCP to registered devices to prevent unregistered devices from communicating with trusted systems.
Block unknown devices and accessories by endpoint security configuration and monitoring agent.
