In the third quarter, Trend Micro found 175,000 different malicious and suspicious packages specifically targeting the Android system. This is a five-fold increase over the previous quarter. This should cause enterprise security managers to sit up and pay attention. The threat is not as serious in the U.S. as it is in countries like Russia and China that use smart phones to pay for services. At this point, there is a massive increase in malware, but an infrequent rate of infection due partly to the problem that the attackers have in making money from the compromised smartphones and tablets. Premium SMS messages are not a popular way to pay for services in the U.S.
One survey found that the average mobile employee packs around three or more devices. At this time, the highest priority for the enterprise is still the data on the devices, contact lists, etc. So if the device is lost or stolen, so is the data. They also need to worry about the inevitable future where malware will succeed in the near future, likely in the next year. The mobile devices are carried in and out of many networks as employees travel through their day. Juniper Networks has developed software to help companies manage and secure their employees' smartphones. Each year, they detect 2 to 3 percent of a client company's smartphones to be infected with malware, usually in the form of spyware.
Expected types of malware would be scareware attempts that convince a victim to pay a fee to clean off their phone, bot-like programs that would turn the phone into a text message spammer, and bank trojans that attempt to steal login credentials to transfer funds.
As a security manager, the future of mobile device malware should definitely be in your line of sites as you plan the future of risk management for your company.
