Microsoft will make a recent hacker meeting held at its Washington headquarters a twice-yearly event, according to a spokesman for the vendor's security group.

The company plans to host another "Blue Hat" security event in the autumn, though no specific date has been set, Stephen Toulouse, a program manager in Microsoft's security unit, said on Monday.

"We're looking at doing this again in the future," he said of the two-day event, held in March. "As we continue to engage with security researchers, we’ve become more comfortable getting into these face-to-face interactions with them."

The Blue Hat name is a reference to the annual Black Hat security conference but blue is the colour of the badges Microsoft employees wear on campus. In sessions at the initial Microsoft Blue Hat event, security researchers demonstrated to both Microsoft executives and developers how flaws in the software giant's products could be exploited.

In one presentation, hackers set up a wireless network and showed how a laptop running Windows XP Service Pack 2 could be lured into joining a potentially malicious network, Toulouse said. Demonstrating these kinds of possible security holes really hit home with product developers, which is why Microsoft wants to host the event regularly, he said.

"There was a moment where everything just stopped," Toulouse said of the wireless network presentation. "You've got guys in the audience who wrote that code ... Some of the things developers coming out of the talks were expressing [were] great ideas to go off and change the way products are [developed] to make sure this won't happen again."

Such warm feelings are unlikely to be challenged however when hackers do things the company isn't so comfortable with - a prime example being the news that Microsoft's brand-new anti-piracy measures had been cracked just a day after their release.
