Hello, I've stumbled upon an information about vulnerable SIM cards that have rather weak encryption. They've said that more than 25% of all SIM cards all over the world have that vulnerability. I'd like to know how exactly it works and is there a way to protect my data and money on my account from that?

Hello, Jim!

We at Jammer-Store Company are aware of the problem and we will you provide with the information, we've got on the subject. So, Karsten Nohl chief of Security Research Labs published the data on the vulnerability he has discovered in DES encrypted SIM cards. First of all, DES encryption standard is rather obsolete, but is still used by major SIM cards manufacturers and mobile carriers. That security gap allows evildoers too get a specific 56-bits encryption key, by sending a fake message to the phone.

That code allows evildoer to send a specific malicious code directly to the cell phone and get personal user's information, intercept SMS messages and even make payments form the user's account. The whole operation of hacking a phone, utilizing that vulnerability takes about 2 minutes. Also, keep in mind that your location may be found with cell phone tower triangulation if your mobile gadget is compromised.

Karsten Nohl has reported about the exploit he found to GSMA association and informed major carriers. But the problem is still unsolved. The results of his research will be puplished on the 1st of August at the Black Hat conference and also, he will tell what carriers are using those vulnerable SIM cards in December. While the bug is not fixed, the only way to protect your phone is to use a cell phone jamming device. We hope that the problem will be solved by December 2013.

Thanks for your question, I hope, I've managed to help.
