Malware remains the most dangerous threat to users of mobile devices. As we discussed on the previous page, malware can rob you of sensitive information such as passwords and account numbers, charge your phone bill or spread it like a virus through your address book. According to web security company Juniper Networks, malware-related attacks on mobile devices increased 250 percent from 2009 to 2010 and 400 percent from 2010 to 2011. With smaller devices, they become easier and easier to lose.
The more we trust these devices, the bigger the consequences if they fall into the wrong hands, are to send and save messages, access our bank accounts and conduct business. Remote lock and remote wipe are two of the most efficient mobile security measures. Enterprise Mobile Security Systems always include this feature, which enables a user or IT manager to lock the phone if they are lost and even remotely wipe their entire memory. Many devices also include GPS tracking capabilities for finding the telephone or even for triggering “screaming” alarms from under the laundry basket of your user.
Network security is less a threat because most cellular data network communications are strongly encrypted. An unencrypted WiFi network is a remaining threat. Be careful to send e-mails or texts to the local café via a WiFi network. You may be able to listen to a WiFi “sniffer” on traffic and troll for useful information.
Anyone who uses email or the Web uses other security threats. For example in a phishing scam, a hacker sends an e-mail posing as a legitimate bank or business and asks the user to enter his password or other sensitive account information. As more people get their emails from mobile devices, they need to take the same caution at home or in the office.
Let us now look at one of malicious hackers ‘ most lucrative targets: mobile banking.
