ATT&CK analytic guidance

DET0568 Detection Strategy for Input Injection

AN1567 Analytic 1567

Detects suspicious USB HID device enumeration and keystroke injection patterns, such as rapid sequences of input with no user context, scripts executed through simulated keystrokes, or rogue devices presenting themselves as keyboards.

AN1568 Analytic 1568

Detects USB HID device enumeration under `/sys/bus/usb/devices/` and rapid keystroke injection resulting in command execution such as bash or Python scripts launched without interactive user activity.

AN1569 Analytic 1569

Detects abnormal HID device enumeration via I/O Registry (ioreg -p IOUSB) and keystroke injection targeting AppleScript, osascript, or PowerShell equivalents. Defender correlates new USB device connections with rapid script execution.
