Malicious threats to Smartphones

摘要

The integration of the Personal Digital Assistant (PDA) and the cellular phone into the Smartphone presents a considerable security risk. Many Smartphones are sold to corporate users who use them for business and personal tasks. The threat is serious that malicious code could destroy the device, gain access to sensitive information or access corporate networks illegally. In addition, packetized services, such as GPRS (General Packet Radio Service), and the move to 3G systems open up more vulnerabilities to hackers. With more open systems with rich content and applications accessible over the air, better security is needed to protect handsets. This article explores malicious code threats on the Symbian and Microsoft Smartphone platforms.
