Cell Phone Viruses & Security Cell Phone Viruses & Security Presentation Transcript

  • What is the common communication medium among us??????? CELL PHONE VIRUSES & SECURITY
    • A Cell Phone
    CELL PHONE VIRUSES & SECURITY
  • Cell phone Viruses and Security
      • 1
  • Outline
    • The technology of cell phones
    • Viruses
    • How Cell phone viruses work
    • Difference with PC virus
    • Different Types Of Cell Phone Viruses
    • Security Issue
    CELL PHONE VIRUSES & SECURITY
  • The technology of cell phones (NETWORK)
    • Analog networks
    • Digital networks
  • Analog networks
    • Today all providers have switched to digital networks and only a few of them are still running analog networks.
    CELL PHONE VIRUSES & SECURITY
  • Digital networks
    • FDMA ( Frequency division multiple access )
    • CDMA (Code-Division Multiple Access)
    • TDMA (Time Division Multiple Access)
    • GSM (Global System for Mobile communication)
    CELL PHONE VIRUSES & SECURITY
  • FDMA CELL PHONE VIRUSES & SECURITY In FDMA, each phone uses a different frequency.
  • CDMA CELL PHONE VIRUSES & SECURITY In CDMA, each phone's data has a unique code
  • TDMA CELL PHONE VIRUSES & SECURITY TDMA splits a frequency into time slots .
  • GSM CELL PHONE VIRUSES & SECURITY
  • GSM
    • Subscriber Identity Module
    • Some operators will block this by allowing the phone to use only a single SIM
    • The locking applies to the handset, identified by its International Mobile Equipment Identity (IMEI) number, not to the account
    CELL PHONE VIRUSES & SECURITY
  • viruses
    • Cell phone viruses are electronic programs that attacks cell phones and PDA (personal digital assistants) devices & malfunction s/w that are running cell phones.
    • HOW THE SPREAD
    • Internet downloads
    • Bluetooth wireless connection
    • Multimedia Messaging Service
    CELL PHONE VIRUSES & SECURITY
  • Threats by Cell Phone malware
    • For financial gain / loss
        • Unnecessary calls / SMS / MMS
        • Send and sell private information
    • Cause phones to work slowly or crash
    • Wipe out contact books and other information on the phone
    • Remote control of the phone
    • Install “false” applications
    CELL PHONE VIRUSES & SECURITY
  • Differences with PC
    • Although similar OSes are being used, differences exist:
      • Lesser users of Cell Phones are “tech literate”
      • Implies that it is difficult to “rollout security patches” to phones already sold
      • Cell Phones are always “connected” and switched on
      • “ Environment” keeps changing
        • Imagine one infected phone in a stadium full of people
    CELL PHONE VIRUSES & SECURITY
  • Differences...
    • On the positive side:
      • Several variants of phones exist
        • A malware for one type of phone may not necessarily be able to infect others
          • E.g., A virus that uses an MMS exploit cannot infect a phone that does not have that facility at all
      • Cell Phone malware not yet causing critical harm
        • At most
          • they increase the user's billing, or
          • cause the Cell Phone phone to stop working (can be restored by a factory reset)
    CELL PHONE VIRUSES & SECURITY
  • Different types of known Cell Phones Viruses
    • Timifonica
    • Cabir
    • Commwarrior
    • Comwar
    • Duts
    • Skulls
    • Lasco.A
    CELL PHONE VIRUSES & SECURITY
  • Case study - Timifonica
    • This virus was reported in 2000.
    • This was one of the first viruses that forced infected PCs to send text messages to phones.
    • the worm has not affected mobile users yet. It was just theoretical threat.
    CELL PHONE VIRUSES & SECURITY
  • Case Study – CABIR
    • First Cell Phone worm
    • Spread vector – Bluetooth
    • Infected file – caribe.sis
    • 15 new variants exist
    CELL PHONE VIRUSES & SECURITY
  • Case Study – Commwarrior
    • Reported in March 2005.
    • It infects mainly phones running Symbian OS
    • The worm replicates itself through the phone's Multimedia Messaging System (MMS)
    • Spread through Bluetooth
    • Commwarrior also read the user's local address book for phone numbers and will then start sending MMS messages containing Commwarrior.
    CELL PHONE VIRUSES & SECURITY
  • Case Study - ComWar
    • Second landmark in Cell Phone worms
    • Spread vector - Bluetooth and MMS
    • Large spread area due to MMS
    • Not as proof of concept – Intention to harm by charging the Cell Phone user
    • Multiple variants detected
    CELL PHONE VIRUSES & SECURITY
  • Case Study - Duts
      • It is the first known virus to infect cell phones and PC as well
      • Case Study- skull
      • The Skulls virus replaces all phone desktop icons with images of a skull.
      • MMS & SMS will no longer be usable
    CELL PHONE VIRUSES & SECURITY
  • Case Study lasco.A
    • The Lasco.A is activated when cell phone user clicks on the file and installs it
    • It spread same as above mentioned viruses
    • This Symbian malware was common for PCs, but now it is present in cell systems too
    CELL PHONE VIRUSES & SECURITY
