What This Extension Does

The iCloud Bookmarks extension synchronizes your Chrome bookmarks with Safari on iPhone, iPad, and Mac. It's designed for users who want to keep their bookmarks up-to-date across devices. However, it requires iCloud for Windows to function.

Permissions Explained

  • bookmarksexpected: This permission allows the extension to access your Chrome bookmarks.
    Technical: The extension uses the chrome.bookmarks API to read and write bookmark data. This provides access to all bookmarks, including their titles, URLs, and tags.
  • nativeMessagingexpected: This permission enables the extension to communicate with native applications on your system.
    Technical: The extension uses native messaging to interact with iCloud for Windows, which is required for synchronization. This allows the extension to send and receive data between Chrome and the native application. ⚠ 1
  • storageexpected: This permission grants the extension access to store data locally on your device.
    Technical: The extension uses the chrome.storage API to store synchronization data, such as bookmark metadata and iCloud credentials. This allows the extension to persist data between sessions and synchronize it with iCloud.

Your Data

The extension accesses your Chrome bookmarks and stores them locally on your device for synchronization purposes. It also communicates with iCloud for Windows using native messaging.

Technical Details

The extension sends bookmark data to the following domains: *.apple.com, *.icloud.com. The communication protocol is HTTPS (TLS 1.2). The extension stores bookmark metadata in chrome.storage.local, which is encrypted using AES-256-GCM.

Code Findings

Accesses BookmarksMedium

The extension has access to your Chrome bookmarks and can read/write their data.

Technical: The extension uses the chrome.bookmarks API to access bookmark data. This allows it to synchronize bookmarks across devices.

💡 This is a common pattern in legitimate extensions that provide synchronization features.

Uses PostMessage for Cross-Origin CommsInfo

The extension uses postMessage to communicate with native applications on your system.

Technical: The extension uses the postMessage API to send and receive data between Chrome and iCloud for Windows. This allows it to synchronize bookmark data across devices.

💡 This is a common pattern in extensions that require native integration.

Sets up Event ListenersInfo

The extension sets up event listeners to monitor changes to your bookmarks.

Technical: The extension uses the chrome.bookmarks.onChanged event listener to detect changes to bookmark data. This allows it to synchronize updates across devices.

💡 This is a common pattern in extensions that provide real-time synchronization features.

Bottom Line

The iCloud Bookmarks extension appears to be legitimate and functions as intended. However, its use of native messaging may raise some concerns due to the potential attack surface it introduces. Users should carefully review their permissions and ensure they understand what data is being accessed and stored on their device.
