The civil liberties group's complaint for injunctive relief with the FTC (PDF), notes that 'major wireless carriers have sold millions of Android smartphones to consumers' but that 'the vast majority of these devices rarely receive software security updates.' The ACLU says carriers leave their customers vulnerable to malware and spear phishing attacks that can be used to record or transmit information on the device to' third parties. 'A significant number of consumers are using smartphones running a version of the Android operating system with known, exploitable security vulnerabilities for which fixes have been published by Google, but have not been distributed to consumers' smartphones by the wireless carriers and their handset manufacturer partners,' the ACLU said. Android devices now account for close to 70 percent of new mobile devices sold. The porous security of many of those devices has become a topic of concern. The latest data from Google highlights the challenge facing the company, with just over 25% of Android users running versions 4.1 or 4.2 – the latest versions of the OS, dubbed 'Jelly Bean,' more than six months after its release. In contrast, 40% of Android users are still running the 'Gingerbread' release – versions 2.3.3 through 2.3.7, a two year-old version of the operating system that has known security vulnerabilities."
