Cost to Hack GSM: $1,000 – $100,000
The 64-bit encryption method used by GSM, known as A5/1, was first cracked in theory about 10 years ago, and researchers David Hulton and Steve, who declined to give his last name, said today that expensive equipment to help people crack the encryption has been available online for about 5 years.
Until now, however, it’s been prohibitively expensive for people to get their hands on this technology. If it works, the technology Hulton and Steve are developing should be able to crack GSM encryption in less than 30 minutes with about $1,000 worth of equipment, or in about 30 seconds with $100,000 worth of equipment. The technology could potentially be helpful to law enforcement investigators, but could also be taken advantage of by malicious hackers. Hulton says he plans to commercialize the more expensive version of the technology.
