6 CONCLUSION
In May of this year, a Soyuz TMA-1 spaceship carrying a Russian Cosmonaut and two American Astronauts landed nearly 500km off course after the craft unexpectedly switched to a ballistic re-entry trajectory. Preliminary indications are that the problem was caused by software in the guidance computer in the new, modified version of the spaceship. In the same week, Microsoft’s Passport online information repository system was found to have a major security flaw that enabled an attacker to gain access to a user’s personal information simply by knowing their e-mail address and constructing an appropriate URL.
