## What it is
A proof-of-concept demo of pastejacking: using JavaScript to override a user's clipboard contents when they copy text from a webpage, tricking them into pasting malicious commands into their terminal. It demonstrates clipboard hijacking attacks across Chrome, Firefox, Safari, and Internet Explorer.

## Use cases
- demonstrate clipboard hijacking attacks
- test whether a browser is vulnerable to pastejacking
- educate users about copy-paste terminal attacks
- research clipboard override techniques via copy events
- show how hidden payloads can execute on paste
- raise awareness of phishing via innocent-looking commands

## When to choose
- you need a working demo of pastejacking for security training or awareness
- you are researching browser clipboard API attack vectors
- you want to test terminal paste safety practices

## When to avoid
- you need a production-ready security tool or mitigation library
- you want clipboard management utilities for legitimate apps
- you need a maintained, actively developed project

## Facets
- artifact type: application
- maturity: maintenance
- function: security, browser-extension
- domain: security, web-development, browser-extensions
- platform: browser
- tags: pastejacking, clipboard-hijacking, security-demo, proof-of-concept, social-engineering, web-server
