01A verification prompt appears

The captured page asks the visitor to confirm they are not a robot.

02A command reaches the clipboard

Radar intercepts a PowerShell retrieval-and-execution command instead of an ordinary verification code.

03Windows paste instructions appear

The page asks for Win+X, Windows PowerShell, Ctrl+V and Enter. The retained screenshot shows the sequence.

04Observation stops before execution

Radar retains the command and screenshots without following the operating-system instructions.

What Radar observed

The original isolated browser session displayed a CAPTCHA-style prompt, then a panel claiming a verification code had been copied. Radar intercepted the command and retained readable Win+X, PowerShell, Ctrl+V and Enter instructions.

Why it matters

The copied text combined remote retrieval from lepafonso[.]bz with an execution operator. Following the instructions could run remote content on the visitor’s device; the content and its final effect were not tested.

Observation limits

This finding is supported by an original-session clipboard event and screenshots, not the site name or score alone. Request and RPC-inspection limits restricted other observations. No command was pasted or executed, and no downstream infection is claimed. The walkthrough is an illustration, not a recording.

Recommended response

Close the page without pasting anything. Preserve the public report and review the captured indicators before blocking. If a command was already run, isolate the device and contact your security team.
