Get cookies.txt LOCALLY

Purpose and Intention:

This Chrome extension is designed to allow users to export their browser cookies to a file (cookies.txt) locally. The extension emphasizes that it does not send any information outside the user's device and is open-source.

Key Functionalities:

• Badge Counter:

  • Updates the extension's badge with the number of cookies for the active tab.
  • Listens for changes in cookies, tab updates, tab activation, and window focus to update the badge.
  • Uses the chrome.cookies API to retrieve cookies for the current site.

• Notifications:

  • On extension update, shows a notification to the user with options to view GitHub releases or uninstall the extension.
  • Handles button clicks in the notification to either open the GitHub releases page or initiate self-uninstallation.

• File Saving:

  • Listens for messages (type: 'save') to trigger saving cookies to a file using the saveToFile module.
  • The file is saved locally and there is no indication of network transmission of cookie data.

API Calls:

• chrome.cookies.onChanged
• chrome.tabs.onUpdated, chrome.tabs.onActivated, chrome.windows.onFocusChanged
• chrome.notifications.create, chrome.notifications.onButtonClicked
• chrome.runtime.onInstalled, chrome.runtime.onMessage
• chrome.management.uninstallSelf

Network Activity:

• The only external URL referenced is for opening the GitHub releases page when the user clicks the notification button. There is no automatic or background network communication.

Filesystem Activity:

• Uses a local file save mechanism via the saveToFile module, triggered by user action or message.

Other Security-Relevant Behaviors:

• No evidence of process execution, shell command execution, PowerShell usage, privilege escalation, persistence mechanisms, registry access, file creation outside user-initiated downloads, user creation, or clipboard access.

Potentially Sensitive Code Snippet:

chrome.runtime.onMessage.addListener(async (message, sender, sendResponse) => {
  const { type, target, data } = message || {};
  if (target !== 'background') return;
  if (type === 'save') {
    const { text, name, format, saveAs } = data || {};
    await saveToFile(text, name, format, saveAs);
    sendResponse('done');
    return true;
  }
  return true;
});

• This code listens for a message to save data to a file, but there is no indication that this is triggered by anything other than user action.

Summary:

• The extension's code is straightforward, with no evidence of malicious intent or behavior. All network activity is user-initiated and transparent. No obfuscation is present.
