Accessing Internet through Mobile PC or Mobiles for official purposes, remote access to all business applications may put personal or organizational information at risk
Exposure of Critical Information
Small amounts of wireless signal can travel significant distance and its possible to peep in to these signals using a wireless sniffer. A wireless intruder could expose critical information.
If device is lost or stolen, the entire corporate intranet could be threatened if those devices are not protected by password and other user level security measures
Mobile Viruses can be major threat, particularly with devices that have significant computational capabilities and connectivity options like WLAN, Bluetooth etc
Voice Phishing (Vishing) is one type of attack as you may receive an e-mail or get a pre recorded voice message (From either from bank or some financial institution) informing you that a large transaction which you never performed and basically held up. The message includes a toll-free-number that you call right away to deal with the situation.
When you dial back to the toll-free-number, a voice menu prompts you to enter your card details and pin number etc and the Vishers may ask you to enter other data also such as expiration date, CVV number. If you act without thinking clearly, you might provide all of the information they ask for.
