The faults discovered in the 850 million cellphones could be used by thieves or eavesdroppers to listen in on calls, steal calls and even to impersonate phone owners. Experts at the Technion in Haifa ...

Intercepting mobile phone calls, and decrypting the data, can now be achieved using inexpensive equipment, according to security researcher Karsten Nohl. In a presentation at the Chaos Computer ...

Researchers have found a way to eavesdrop upon any mobile call or text message sent via any GSM network, utilising open source phones that cost as little as $10, it has emerged. Karsten Nohl and ...

Math is hard and cryptography is even harder. So in light of the news that another of the ciphers used to secure traffic on 3G GSM networks has been cracked, we turned to mathematician and ...

It has been long argued that the A5/1 encryption standard used to secure GSM traffic from eavesdropping is, in fact, insecure, and California based security firm H4RDW4RE is pioneering an effort to ...

An encryption algorithm designed to protect calls on GSM phones has been broken by three cryptographers using only a dual-core, Intel -based Dell Latitude PC running Linux. In a paper released Tuesday ...

Mobile calls and texts made on any GSM network can be eavesdropped upon using four cheap phones and open source software, say security researchers. Karsten Nohl and Sylvain Munaut demonstrated their ...
