Microsoft sheds reputation as easy mark for hackers

Redmond, Washington

MICROSOFT was once the epitome of everything wrong with security in technology. Its products were so infested with vulnerabilities that the company's co-founder, Bill Gates, once ordered all of Microsoft engineers to stop writing new code for a month and focus on fixing the bugs in software they had already built.

But in recent years, Microsoft has cleaned up its act, even impressing security specialists like Mikko Hypponen, the chief research officer for F-Secure, a Finnish security company, who used to cringe at Microsoft's practices.
