Understanding Vichatter Captures: The Future of Virtual Interaction

• High-resolution timers and SharedArrayBuffer-based measurements (where available) to infer keystroke timings.
• Cache side-channels (Spectre-class) for inferring activity.

The "capture" functionality on such platforms typically serves several critical purposes for modern digital citizens: vichatter captures

• navigator.clipboard.readText() when permission granted or via paste events.

• Single-page malicious site prompting login: direct capture of credentials and clipboard.
• Supply-chain compromise: third-party widget loaded on many sites capturing input across origins.
• Cross-origin overlay: malicious extension or page creating transparent overlays to capture inputs intended for other apps.
• Social-engineered permission escalation: mimic system prompts to obtain getDisplayMedia/getUserMedia consent.
