This paper examined a wide range of programs that expose your sensitive data. Some store sensitive data as plaintext, other improperly handle this data and give their users a false sense of security — and we are finding more all the time. As illustrated, there are numerous programs that advertise their "security" features to earn your trust, but in reality fail to protect your data from attackers.
Hopefully this paper and the research that went into it will help increase the security awareness for the Windows Mobile community. It is in the best interest of everyone who loves Windows Mobile to advocate stronger coding and greater platform security.
