iOS 15 Image Forensics Analysis and Tools Comparison - Browsers, Mail Clients, and Productivity apps

The fifth episode is dedicated to three categories of third-party apps: browsers, mail clients, and productivity apps.

There are 6 browsers, 3 mail clients, and 3 productivity applications available in Josh Hickman’s acquisition. 

The 6 browsers are listed below, in alphabetical order.

  1. Brave
  2. DuckDuckGo
  3. Firefox
  4. Firefox Focus
  5. Google Chrome
  6. Microsoft Edge

The 3 mail clients are listed below, in alphabetical order.

  1. Gmail
  2. Proton Mail
  3. Tutanota

The 3 productivity applications are listed below, in alphabetical order.

  1. Microsoft Teams
  2. Slack
  3. Zoom

APOLLO has no parsers for third-party apps, while ArtEx only has a parser for Google Chrome.

Each section for each app is structured similarly: first, a list of the most important files and folders is provided, then a description of the tools parsing capabilities for that app, and finally two different tables. The first table provides the details for each action documented by Josh in the iOS 15 image documentation, and the second table provides a summary of the tools’ parsing capabilities based on the test results.

As usual, YES means that the value was parsed and parsed correctly, NO means that the value was not parsed, YELLOW means that it was partially parsed, and BLUE means that the value was found elsewhere (i.e., iOS Notification or iOS Cache).

The rest of the blog post is organized by categories: browsers, email clients, and last productivity applications.

Brave Browser

Relevant information for this application is stored in these files and folders:

  • /private/var/mobile/Containers/Data/Application/<GUID>/Library/Application Support/Brave.sqlite
  • /private/var/mobile/Containers/Data/Application/<GUID>/Library/Application  Support/Chromium/Default/History
  • /private/var/mobile/Containers/Data/Application/<GUID>/Library/Application  Support/Chromium/Default/Login Data
  • /private/var/mobile/Containers/Data/Application/<GUID>/Library/Application  Support/Chromium/Default/Web Data
  • /private/var/mobile/Containers/Data/Application/<GUID>/Library/Application  Support/Chromium/Default/Favicons
  • /private/var/mobile/Containers/Data/Application/<GUID>/Library/Application  Support/Chromium/Default/Preferences
  • /private/var/mobile/Containers/Data/Application/<GUID>/Library/Caches/WebKit/NetworkCache/Version 16/Blobs
  • /private/var/mobile/Containers/Data/Application/<GUID>/Library/Caches/WebKit/NetworkCache/Version 16/Records

Direct parsing of this application is supported by AXIOM, OXYGEN, and BELKASOFT. Oxygen seems to cover this browser in a more complete way: it parses history, cache, cookies, and tabs, while AXIOM only parses tabs and BELKASOFT only parses history. All tools extracted some information about visited websites in normal mode, but not about visited websites in private mode.

Direct parsing of this application is supported by PA, OXYGEN, XAMN, and BELKASOFT. PA, XAMN, and BELKASOFT parsed history and bookmarks, OXYGEN and XAMN parsed cache, and PA and OXYGEN parsed cookies. Traces of websites visited in private mode were found in cache and cookies.

It’s worth noting that none of the tested tools parsed the folder /private/var/mobile/Containers/Shared/AppGroup/<GUID>/profile.profile/TabManagerScreenshots and the file /private/var/mobile/Containers/Data/Application/<GUID>/Documents/favicon-url-cache that contain screenshots of tabs and favicons, including those of webpages visited in private mode.

This secure browser does not store relevant information on the device's internal memory. 

Some execution timestamps can be extracted from:

  • /private/var/mobile/Containers/Data/Application/<GUID>/tmp/

Direct parsing of this application is supported by all tested tools. Oxygen has the most complete parsing capability, while PA and AXIOM also have a good parsing capability, but PA didn’t parse tabs and AXIOM didn’t parse cookies. Traces of websites visited in private mode were found in Tabs.

It’s worth noting that none of the tested tools parsed the folders /private/var/mobile/Containers/Data/Application/<GUID>/Library/Application Support/Google/Chrome/Default/Session/{SyntheticIdentifier}/Snapshots/ and /private/var/mobile/Containers/Data/Application/<GUID>/Library/Application Support/Google/Chrome/Default/OTR/Sessions/{SyntheticIdentifier}/Snapshots/ that contain screenshots of tabs, including those of webpages visited in private mode

Relevant information for this application is stored in an SQLite database:

  • /private/var/mobile/Containers/Shared/AppGroup/<GUID>/ProtonMail.sqlite

Messages are stored in an encrypted way in the database: PA and XAMN are the only tools with a decryption and parsing feature for this database. PA parsed both email header and body, while XAMN only parsed headers. OXYGEN parsed contacts, that are stored unencrypted in the SQLite database.

Final comments

Some final comments after this complex post.

The most commonly used browsers in the iOS world (Safari, Google Chrome, and Mozilla Firefox) are supported by most of the tested tools, but there are still some unexplored areas, like tabs screenshots. Information about websites visited in Private Browsing were recovered for Google Chrome (Tabs), Mozilla Firefox (Tabs, Cookies, Cache, and Favicons), and Microsoft Edge (Tabs). Support for Gmail email client is wide, but encrypted email clients are only supported by some tools (Proton Mail is supported by PA and XAMN) or not supported at all (Tutanota). Common productivity applications like Microsoft Teams and Slack are supported by most of the tested tools and for both of them all tools were also able to recover the deleted message. Zoom databases seem encrypted, so messages were recovered only from iOS notifications.

The following tables contain an overview of which tools parsed which applications. Be careful in evaluating the quality of extracted date, as in some cases tools have a very limited parsing capability (i.e., extracting the user account information).
