Digital Trends – Juniper Networks is raising eyebrows in the mobile industry this morning with a new report claiming the incidence of malware targeting Android devices has risen by 472 percent since July of this year. Presumably, that number is augmented by âhundredsâ of malware samples the company uncovered in a series of third-party Russian app stores. Juniper describes the Russian malware cache as just the âtip of the iceberg,â believing there may be thousands of more malware apps waiting to be discovered.
