Mobile Forensics

Mobile forensics is used to recover digital evidence from a mobile device in a forensically sound manner.

Mobile storage locations: (three)

Internal Phone Memory: It includes data stored in RAM, ROM, or flash memory. It stores the Mobile phone's OS, applications, and data. The investigator can extract information from internal phone memory using AT commands with the help of a USB cable, infrared, or Bluetooth.

SIM Card Memory: It includes data stored in the SIM card memory. The SIM stores personal information, address books, messages, and service-related information.

External Memory: It includes data stored in SD card, MiniSD Card, MicroSD, etc. It stores personal information such as audio, video, and images.

Mobile device forensics process

  1. Collect evidence
  2. Document scene and preserve evidence
  3. Imaging & profiling
  4. Acquire information
  5. Report

What are the components of a cellular network?

  1. Mobile Switching Center (MSC): the switching system for the cellular network
  2. Base Transceiver Station (BTS): radio transceiver equipment that communicates with mobile phones
  3. Base Station Controller (BSC): manages the transceiver’s equipment and performs channel assignment
  4. BSS: Base Station Subsystem is responsible for managing the radio network and is controlled by the Mobile service switching center (MSC). It consists of the elements BSC (Base Station controller), BTS (Base Transceiver Station), and TC (Transcoder)
  5. Home Location Register (HLR): It is the database at MSC. It is the central repository system for subscriber data and service information
  6. Visitor Location Register (VLR): It is the database used in conjunction with the HLR for mobile phones roaming outside their service area How many different cell network types are there?
