Silent Circle has confirmed* allegations* that their privacy software has been completely useless. A memory corruption vulnerability allowed decryption of private messages to any attacker with the victim's user ID or phone number. Silent Circle is no stranger to this kind of embarrassment; a few months after receiving 30 million dollars* in funding, a Blackphone was rooted* by hackers at DEF CON. Discouraged former users of this pathetic device should be comforted to know that proper cryptography will likely* be made user friendly* by the end of the year. Until then, people who wish to obscure their messages from the prying eyes of big brother should stick to the classics*.
