A recent Clickfix sample demonstrates how attackers can use built-in Terminal customization features on Windows 11 systems to make social engineering lures appear more legitimate. This involves altering the appearance of the PowerShell command prompt and terminal output to mimic trusted services like Cloudflare.

These customizations can significantly improve the appearance of a Clickfix lure, making it harder for users to identify suspicious activity. For detection purposes, keywords that alter Terminal appearance could be incorporated into analytics tools like Microsoft Defender for Endpoint (MDE) KQL queries.
KQL examples provided include:
- Detecting Win + X execution.
- Identifying direct Terminal execution.
- Analyzing evasive techniques such as nested command execution and process tree fragmentation using
wt.exe.
