#Sim card hack on a broken phone software
SIM Swapping also known as SIM splitting, SIM jacking, SIM hijacking is basically taking over the control of your mobile operations from your existing SIM to another SIM, that is in control of the cyber fraudster. SIM Swapping and Cloning are online scamming methods in which the fraudsters gain control over your phone number and your mobile is compromised. Mobile SIM swapping and SIM cloning are two such kinds of cyber frauds, being practiced by fraudsters for cheating the mobile subscribers. This wide spread prevalence and usage of mobile technology, has lured the cyber criminals to resort to new and sophisticated ways of committing cybercrimes and frauds.
The mobile phone has revolutionized communication and enabled transaction of every kind possible at the click of button. With the help of a mobile phone, the technology has made everything available on the go for us. Nohl is expected to share his findings at the Black Hat security convention in Las Vegas on July 31.In the current age we are living in a parallel virtual world where mobile phones have become an integral part. He has since shared his findings to various carriers and the GSMA in an effort to help close the exploit before it becomes widespread amongst cybercriminals.

Nohl claims that the dated security standard and badly implemented Java Card code could allow him to compromise the encryption keys of certain SIM cards in less than a minute. AT&T has even said that it had moved on to triple DES (3DES) almost 10 years ago. The four major German carriers, as well Verizon and AT&T in the US have since commented that their SIM cards are not vulnerable. The Data Encryption Standards (DES) security encryption developed back in the 70's has finally been cracked, though. This marks the first time SIM cards have been compromised, as until now it was thought that SIM cards were unhackable. According to his estimates about an eighth of the world's SIM cards could be affected, or about half a billion devices. Nohl says that cards which are affected vary by country and carrier - since encryption standards vary between countries. The exploit could allow a virus to be uploaded and then carry out payment system fraud, redirect and record calls, and more. German cryptographer Karsten Nohl claims to have broken the encryption standard on certain types of SIM cards.
