Washington, DC - Some of the nationÂ’s leading computer science and network security experts today issued a report warning that the computers and critical technological infrastructure worldwide are increasingly vulnerable to attack because of the security practices and dominance of Microsoft software in desktop computing. As a result of MicrosoftÂ’s concerted effort to fortify and expand its monopolies by tightly integrating applications with its operating system, and its success in achieving near ubiquity in personal computing, our computer networks are now susceptible to massive, cascading failures.
