SUNNYVALE, Calif., Dec. 10, 2013 (GLOBE NEWSWIRE) -- Marble Security Labs is issuing a mobile security alert to enterprises warning of an insidious threat called "Jailbreak Jammers." The threat is introduced by the organization's own employees who jailbreak their phones, then download a jammer app to cover their tracks so they can still access the company's network.

The risks of Jammers affect any enterprises that allow employees or customers to access their systems from mobile devices such as iPhones, iPads and Android smartphones or tablets.

"This is a significant risk to the enterprise, especially those allowing BYOD, because experience shows us that even just one compromised device can eventually lead to a massive breach," said Marble Security Founder and CTO David Jevans. "Jailbreak Jammers are evolving like crazy. It is a great example of why you need a mobile security lab to make a mobile security platform effective."

Marble discovered this new category of malicious code as part of its labs' ongoing program of scanning mobile apps for new threats.

While end users may jailbreak a device in order to access free apps or content, network security teams understand that jailbroken iPhones and iPads, and rooted Android devices, pose a huge threat to organizations.  In fact, jailbroken or rooted devices have virtually zero security, allowing hackers to gain access to company data, emails, passwords and address books.

Many organizations have installed mobile device management (MDM) solutions to help detect jailbroken or rooted devices and prevent them from coming onto the network. Now, however, some people who have their jailbroken devices blocked from network access are downloading and applying jammers to defeat MDM jailbreak detection. Plain old MDM products, however, lack mobile security research labs, fail to detect jammers and, in fact, grant the jailbroken or rooted devices full connectivity privileges.

Research from the labs supports the Marble mobile security platform, a next generation cloud service that combines advanced mobile security management (MSM) functionality with essential mobile app management (MAM) and MDM capabilities. It includes advanced features like app scanning, secure browsing and real-time cyberthreat protection.
