title: GUI Input Capture (T1056.002)
id: df00tech-t1056-002
status: experimental
description: "Adversaries may mimic common operating system GUI components to prompt users for credentials with a seemingly legitimate prompt. This includes spoofing Windows UAC dialogs, macOS authentication prompts, or application-specific login windows using scripting languages such as PowerShell, AppleScript, or shell scripts. Threat actors leverage this technique to harvest credentials without exploiting technical vulnerabilities, instead relying on user trust in familiar UI elements. Real-world examples include Proton, Calisto, Keydnap, FIN4, and RedCurl using fake dialogs to steal credentials."
