Trojan on cell phones

'Skulls' Trojan Taking Out Cell Phones with Symbian OS
Unsurprisingly, hackers started to write trojans for cell phones. As more and more high-speed wireless bearers have brought up, attackers have more extent in writing malicious worms. Just like the early stages of Internet, compromising systems were vulnerable to these attacks. Anti-virus programs, firewalls and other related software are then released to battle these intruders. Most likely, mobile devices which have the accessibility to mobile networks will face these kind of circumstances in the near future.
Obviously, mobile devices like mobile phones are not designed to be attacked. One of the reasons why attackers are interested in writing trojans is because the information they retrieve can earn money. As the number of mobile phone users grows, more and more information are scattered around the air. That means more and more trojans are likely to be spread in the coming era. Thus, mobile phones should be evolved to adapt the insecure medium. Higher processing power, larger memory size and smaller electrical components may probably be the essential requirements to accommodate this drastic change. As security features are brought into mobile phones, more applications could be integrated and mobile phones will no longer be used solely for making and receiving phone calls.
