Encrypted Blackphone Patches Serious Modem Flaw (threatpost.com)

msm1267 writes: Silent Circle, makers of the security and privacy focused Blackphone, have patched a vulnerability that could allow a malicious mobile application or remote attacker to access the device's modem and perform any number of actions. Researchers at SentinelOne discovered an open socket on the Blackphone that an attacker could abuse to intercept calls, set call forwarding, read SMS messages, mute the phone and more. Blackphone is marketed toward privacy-conscious users; it includes encrypted messaging apps such as SilentText and Silent Phone, and it runs on a customized, secure version of Android, called PrivatOS.
