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.
