The Palm OS operating system for Personal Digital Assistants (PDAs) and mobile phones has a weak security architecture, which introduces all sorts of security problems. This paper specifically targets the problem of malicious code. The main contribution of this work is the in-depth analysis of different vulnerabilities in Palm OS and the ways in which they can be exploited by malicious code.
