Hackers can easily enter any GSM phone to steal money and service or to launch attacks.
Hackers can infiltrate almost any GSM phone, a sign that security in the mobile phone world is still inadequate. About 4 out of every 5 mobile phones in use around the world use a GSM network. In the USA, GSM phones operate on AT&T, T-Mobile and other wireless carriers.
After taking control of a GSM mobile phone, hackers can use the phone to place calls, send text message and take other actions, a new report says.
GSM vs. CDMA
Global System for Mobile Communication (GSM) phones have SIM chips that users can readily switch out, allowing them to use their phones on different carriers, explaining why the phones are popular among international travelers. Although that type of wireless network is popular overseas, the American market also uses the Code Division Multiple Access (CDMA) phone system, which is used by Sprint, Verizon and other companies. Because CDMA is not widely adopted in foreign markets, Americans with CDMA phones usually must buy a separate GSM phone to use as they travel.
CDMA phones are not vulnerable to the recently-discovered hack.
Details of GSM hack
A German research lab released a study that shows that hackers can easily compromise almost any GSM phone on any GSM network, suggesting that mobile phone users are even less secure than they already know. Even worse, the flaw enables hackers to form GSM phone banks that can wreak havoc on mobile networks similar to the way bot nets affect computer networks.
Other than the general concept, few details of the GSM vulnerability have been released, a sign that the media and the security researcher who made the discovery want to contain any possible outbreak of malicious behavior.
A Word of Caution
Until GSM network operators enhance their security practices, GSM phone users should beware that their devices can be hijacked at any time. This could lead to substantial phone bills that might only be partially refunded by phone carriers. According to the Daily Mail, some schemes exist that allow hackers to transfer money from one phone account to another.
According to a GSMmap.org, an analysis of GSM networks shows T-Mobile as the most secure U.S. GSM network. It is least susceptible to attacks involving impersonation, interception and tracking.
Well in this situation I’m feeling very insecure. I’m using GSM phones and according to your post it’s no longer protected and as well my documents. Thanks for informing and I hope mobile developers will soon sort out a solid way to reduce intruder attack.
