DNS bug tattler not the first to guess flaw details

Two weeks of silence helped, says researcher who found critical flaw

Kaminsky said the short-term impact from the bug going public is that some administrators will have to take down their networks unexpectedly in order to patch.

But he had little sympathy for those who had brushed off his earlier warnings. "Some people said,'I can't justify doing anything without knowledge of the exploit,'" Kaminsky said. "To those people, all I can say is,'So, do you feel safer now?'"

Kaminsky also had words for security researchers who don't understand how difficult it is to organize a large-scale patching effort, or even how much time it takes to patch a widespread flaw throughout a corporation's network. "Our job as security researchers isn't just to find bugs, but to get them fixed," he argued. "Breaking stuff is easy. Who has the easier job? The one who finds the bug or the one who helps fix it? The hacker has the easier job here.

"This isn't a trivial patch. It's going to take a huge amount of effort. A lot of organizations are going to be rough on their IT staffs to get this done."

He was encouraged, however, by the progress that had been made in patching the bug, even in just 13 days. "There are a lot of people who have patched, not a majority, but 30 per cent to 40 per cent of those tested [using a widget on Kaminsky's site were safe. Those are enormous numbers for such a short time. Is that everyone? No," said Kaminsky. "But those that started [when patches were first available] have a two-week head start over those who waited."

Kaminsky, however, wasn't ready to get specific about what he would have done differently. Those lessons, he said, would have to wait until after Black Hat. "I did everything I could for my customers," he concluded. "I have taken a lot of dings, but I would do it again."

Ultimately this laptop has achieved everything I would hope for in a laptop for work, while fitting that into a form factor and weight that is remarkable.

It really doesn’t get more “gaming laptop” than this.

Jack Jeffries

MSI GS75

As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

The MSI PS63 is an amazing laptop and I would definitely consider buying one in the future.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
