OS Paste Warnings Against ClickFix

Operating systems can detect and interrupt social‑engineering paste attacks (so‑called ClickFix), prompting users before executing pasted commands in shells or run dialogs. That UX-level defense reduces the success of scam scripts while also creating new usability tradeoffs and attacker workarounds. — This matters because operating systems taking on behavioral security (warnings, blocks) shifts responsibility onto platform vendors, changes attacker incentives, and raises questions about where usability, security, and paternalism should be balanced.
