SIMJACKER - AUSTRALIAN MOBILE USERS ARE SAFE SAY TELCOS

摘要

As background, the SIMjacker vulnerability was related to the use of 'intelligent' SIM cards that were capable of processing configuration commands issued by the phone operator. Well, that was the theory. In fact, the interface was almost totally unprotected and was able to blithely execute any commands delivered to the device by a "bad dude." The original research paper estimated that around 1 billion phones might be vulnerable, suggesting that another two billion or so were not (based on an estimate of around 3 billion active devices). In response to our questioning, a Telstra spokesperson told us, "We don't believe our SIM cards are vulnerable to SIMJacker, however we are actively reviewing information as it becomes available and, as always, we continue to collaborate with researchers and the industry on this and other cyber security matters."
