ClipShield

ClipShield stops dangerous copy/paste attacks before they reach your system. Scam pages, fake verification prompts, and ClickFix-style lures increasingly try to trick users into pasting harmful commands into PowerShell, Terminal, or Command Prompt. ClipShield detects those threats in real time by watching for suspicious clipboard payloads, deceptive on-page instructions, programmatic clipboard writes, and known social-engineering patterns. When a threat is detected, ClipShield can block the payload, clear the clipboard when needed, and show a clear warning before damage is done. Why install ClipShield: - Real-time protection against malicious copy/paste scams - Detects ClickFix-style lures and fake verification flows - Flags dangerous command patterns and remote fetch-and-run chains - Monitors suspicious clipboard manipulation on websites - Includes a local threat log and trusted-domain allow list - Client-side only, zero telemetry, and open source - ClipShield currently includes 240 detection rules and 71 lure phrases focused on real-world clipboard abuse and command-execution attacks. 100% Open & Free https://github.com/xorjosh/ClipShield
