After three years of research and testing over a thousand SIM cards, an investigator German Security Research Labs discovered a flaw that allows pirating responsible for communications chips for mobile phones. After so many years of immunity, after all it is possible to remove these information cards in just two minutes.
German researcher Karsten Nohl discovered a problem in cryptography chips present in the SIM card, which allows you to copy or redirect existing data on the cards.
According to Mashable, this vulnerability discovery now allows pirating chips based on the old encryption standard called DES (Digital Encryption Standard), and Exame said that one in four SIMCard have this problem.
Although Karsten Nohl believe that nobody has explored and taken advantage of this problem, the researcher admits that the cloning process information is relatively simple, quick and easy, taking “two minutes.”
When you receive an SMS
invisible passes the phone to be controlled remotely, allowing the sending of messages to multiple numbers, call recording and redirection links, without the card owner being aware of it.
Nohl estimates that the number of cards affected with this problem is around 750 million.
The GSM Association, card manufacturers and telecom operators are already aware of the issue and volunteered to solve the problem ASAP.
