A wide range of Android phones are vulnerable to attacks that fully compromise the devices at their deepest level: the baseband. Fixes have yet to be delivered, except to a subset of vulnerable Pixels. In the meantime, Google and Samsung advise, users should do something that's not possible for most vulnerable devices: turn off VoLTE. Both Google and Samsung declined to provide further, actionable guidance to at-risk customers. Worse, even if/when it's possible to turn off VoLTE, this advice completely neuters most phones of any kind of voice calling capability.
This incident once again underscores the security mess of the Android ecosystem. It also demonstrates the lack of cooperation Google and Samsung regularly exhibit in keeping their customers safe.
Super sad.
