The vast majority of currently existing malware for mobile devices (PDAs, smart phones, etc.) is for mobile phones running the Symbian S60 R2 operating system - with just some proof-of-concept malicious programs existing for the J2ME, PalmOS and Windows Mobile 2003 environments. The paper examines the security features introduced in the newer versions of the mobile operating systems - Symbian R3, Windows Mobile 6.0, J2ME - and explains why they are much less vulnerable to self-propagating code. While we stop short of claiming that these environments are virus-proof, we maintain that viruses are unlikely to become a huge problem for them.
