Expert finds data security flaw in wireless technology

A widely used wireless technology may have some security flaws, according to a security expert. Karsten Nohl, managing director of Security Research Labs, said GMS technology has data security vulnerabilities, according to Reuters. This technology is used by 80 percent of the world, CRN said. ECommerce companies need to be careful to use only credible and secure technology, especially when it comes to handling credit card data.

Nohl said GSM technology - Global System for Mobile Communications - is vulnerable to tapping and said the industry needs to beef up these security flaws. Smartphones and tablets use wireless networks and are seeing increased sales, so the security gap needs to be addressed quickly in order to prevent widespread fraud. The GSMA, an industry lobbying group, released a statement saying it is not worried about the new findings.

"The GSMA and its mobile network operator members are confident in the security of existing 2G GSM networks and real attacks on real networks against real customers are most unlikely," the group said.

Nohl said the security flaw could affect hundreds of thousands of phones at once. ECommerce companies should look to increase IT security and follow PCI compliance.
