Over three quarters of Android threats are malicious apps that send SMS messages to premium rate numbers and could be mitigated by a protection feature present in Android 4.2, according to researchers from networking vendor Juniper Networks.
However, because manufacturers and carriers fail to update Android end-user devices in a timely fashion, only 4 percent of devices currently run Android 4.2, even though this version was released more than six months ago.
From March 2012 to March 2013, the number of mobile threats grew by 614 percent to reach a total of 276,259 malicious samples, researchers from Juniper Networks’ Mobile Threat Center (MTC) said in a report released Wednesday. Of those malicious applications, 92 percent target the buy prescription propecia without Android operating system, they said.
The surge of Android malware in the past two years is consistent with the findings of other security vendors that track mobile threats. This growth is primarily driven by Android’s “commanding share” of the global smartphone market, the Juniper researchers said.
The majority of Android malware, 77 percent, are cost of propecia apps that earn money for their creators by either requiring users to send SMS messages to premium rate numbers or by surreptitiously sending such messages on their own. These threats usually masquerade as legitimate applications or come sale levitra bundled in pirated apps.
The Juniper researchers estimate that every successful attack using such an app can bring an immediate profit of $10 for the attacker on average.
Android 4.2 introduced a feature that detects attempts to send SMS messages to special rate numbers, also known as short codes, viagra uk and prompts users for confirmation. Unfortunately, due to the Android market fragmentation, only 4 percent of Android devices are currently running Android 4.2.x.
This estimation is based on data collected from Google Play over a 14-day period ending on May 1, 2013, the Juniper researchers said. Based on the same data, the most common versions of Android found on devices are Android 2.3.3 to 2.3.7, also known as “Gingerbread,” with a 36.4 percent coverage and Android 4.0.3 and 4.0.4, also known as “Ice Cream Sandwich,” with 25.5 percent.
The lack of regular updates for Android devices contributes to the growth of Android malware, I tried so many brand of this product over 10yrs. This product is the best: viagra original pfizer order. Every discount drug order from Canada Drugs is backed by our No-Risk Guarantee that guarantees you 100% free shipping on every order. because the latest protections added by Google to the operating systems reach users too late or never, the researchers said.
The second most common type of Android threats are spyware applications that capture and transfer sensitive user data cheap levitra to attackers. These account for 19 percent of all malicious samples collected by Juniper’s MTC.
Some information-stealing Android Trojan apps discovered during the past year and distributed through drive-by downloads or phishing emails could also pose a threat to enterprise environments, the Juniper researchers said. Data collected from enterprise mobile devices running Juniper’s Junos Pulse endpoint collaboration and security software showed at least one infection on 3.1 percent of such devices.
While that figure is not large enough to raise a significant alarm, it is proof that the threat of mobile malware to corporate devices is not only theoretical, the Juniper researchers said. “We expect the presence of mobile malware in the enterprise to grow exponentially in the coming years.”
