<p>Adversaries may use methods of capturing user input to obtain credentials or collect information. During normal system usage, users often provide credentials to various different locations, such as login pages/portals or system dialog boxes. Input capture mechanisms may be transparent to the user (e.g. Credential API Hooking) or rely on deceiving the user into providing input into what they believe to be a genuine service (e.g. Web Portal Capture).</p>

Detection strategy · ATT&CK Enterprise v19.2

DET0102 Behavioral Detection of Input Capture Across Platforms v1.0
AN0282 Windows
Monitors for abnormal process behavior and API calls like SetWindowsHookEx, GetAsyncKeyState, or device input polling commonly used for keystroke logging.

WinEventLog:Sysmon EventCode=10 → DC0035 Process Access
WinEventLog:Security EventCode=4663, 4670, 4656 → DC0055 File Access

Tunable: TargetImage TimeWindow

AN0283 Linux
Detects use of tools/scripts accessing input devices like /dev/input/* or evdev via suspicious processes lacking GUI context.

auditd:SYSCALL open, read → DC0055 File Access
auditd:SYSCALL write → DC0061 File Modification
auditd:SYSCALL ptrace, ioctl → DC0021 OS API Execution

Tunable: ProcessName DevicePath

AN0284 macOS
Monitors for TCC-bypassing or unauthorized access to input services like IOHIDSystem or Quartz Event Services used in keylogging or screen monitoring.

macos:unifiedlog subsystem=com.apple.TCC → DC0034 Process Metadata
macos:osquery launchd or process_events → DC0032 Process Creation

Tunable: Service ParentProcess

AN0285 Network Devices
Detects web-based credential phishing by analyzing traffic to suspicious URLs that mimic login portals and POST credential content.

NSM:Flow http.log → DC0085 Network Traffic Content
NSM:Firewall proxy or TLS inspection logs → DC0082 Network Connection Creation

Tunable: UserAgent URL_Path

Suspicious Network Communication With IPFS lowtest

Author: Gavin Knapp · 2023-03-16 · logsource: category=proxy · eb6c2004-1cef-427f-8885-9042974e5eb6

Detects connections to interplanetary file system (IPFS) containing a user's email address which mirrors behaviours observed in recent phishing campaigns leveraging IPFS to host credential harvesting webpages.
