How to Extract Data from Vault Apps

What are Vault Apps?

Vault and private storage apps allow users to hide content like photos, videos, messages, contacts, calls, browsing history, notes, and other sensitive data within a device. Usually, vault apps are password-protected and even encrypted.

These apps guarantee privacy and safe storage of user’s confidential data. However, vault apps can also be utilized to hide illicit content and SCAM. Moreover, vault apps might do the opposite thing – being a malware spy on their users.

Newly Supported Vault Apps

FileSafe extraction

With FileSafe a user can hide their files and folders and access them using a secret PIN code. Oxygen Forensic® Detective enables extraction of the following artifacts from Android devices, if physical or full file system methods are used:

  • Account info
  • PIN code
  • Images, audio, and video files
  • Cached images

Extraction of Calculator+ , Calculator#, and SafeCalc apps

All these apps are disguised as a full-featured calculator. However, they are vault apps that can hide photos, videos, bookmarks, notes, contacts, passwords, and other sensitive data. For their extraction, we recommend the checkm8 method. However, investigators can also extract them using the iTunes backup procedure.

Data that can be extracted from Calculator+:
