Secret Agent Cell Phones

Article: At Israel's nuclear reactor, employees' cell phones are disabled as soon as they enter work. They cannot text, email or surf the internet; they can only make calls. This is to prevent the possibility of cyber attacks or the capturing of sensitive information by the phones. Apparently cyber attacks are so complex now, they can be performed remotely through cell phones, merely by their being on. Other high-tech companies in Israel are demanding the same thing from their workers, so that competitors can't see groundbreaking technology in the works. This includes taking out the cellphone battery so conversations can't be taped.

Discussion:

• Why are people worried about spying and cyber attacks through cellphones? 
• How did cell phones have this capability to "steal" information? 
• If you were a secret agent, how would you capture necessary info?
