For years, the security of cell phones have been debated and speculation has been that there was a major vulnerability present. Karsten Nohl has presented at a communication conference in Berlin that cell phones indeed can be hacked:
“Computer hackers this week said they had cracked and published the secret code that protects 80 per cent of the world’s mobile phones. The move will leave more than 3bn people vulnerable to having their calls intercepted, and could force mobile phone operators into a costly upgrade of their networks.
Karsten Nohl, a German encryption expert, said he had organised the hack to demonstrate the weaknesses of the security measures protecting the global system for mobile communication (GSM) and to push mobile operators to improve their systems.”
The significance of this disclosure, if proven to be valid, would be monumental. It would mean that cell phone security would require a massive upgrade, along with considerable costs to the provider. Of course, the end user would bear the eventual financial burden. At the moment, only the 3G calls are considered secure.
