GSM Mobile Security at Risk

GSM, the world's most popular standard for mobile phones, has a reason to feel insecure.Researchers at the Black Hat Europe 2008 conference on Friday demonstrated how they could break GSM's encryption using relatively inexpensive off-the-shelf equipment and software tools. More specifically, they cracked an algorithm used to encypt conversations in the hopes of motivating mobile carriers to better secure their networks so that users' privacy and data won't be at risk.

David Hulton, one of the researchers, said it typically takes a loss in revenue for such change to occur. "Attacks will always get better; they'll never get worse," he said.

More than 2 billion people worldwide access GSM and 3GSM services, according to the GSM Association.Computerworld
