Google has just posted the first ever monthly security update for Nexus devices, as promised during the BlackHat Conference in August.

After suffering embarrassment over the much-publicized Stagefright vulnerability, a bug that, if fully exploited, allowed an attacker to send malicious code via a simple SMS, Google has released the first ever monthly security update for Google Nexus devices, reports ArsTechnica.

The widely reported Stagefright vulnerability was a bug in the Android ecosystem’s “Stagefright” media library. Although significant in its malicious nature, the potential damage that may have been the outcome from the bug was curbed thanks to exploit mitigation techniques in newer versions of Android. Still, the bug firmly planted the spotlight on Android’s easily exploitable security structure.

Android is among the most widely used operating systems in the world, powering over a billion mobile devices including phones, tablets and other devices.

The Screaming Need for Better Android Security

The publicity gained from the Stagefright bug spurred action from Google, OEM (Original Equipment Manufacturers such as Samsung, LG, etc. ) & carriers to start paying attention to pushing through security updates to end-users routinely.
