The Over-Optimization Meltdown

In simple terms, Meltdown and Spectre are simple vulnerabilities to understand. Imagine a gang of thieves waiting for a stage coach carrying a month's worth of payroll. There are two roads the coach could take, and a fork, or a branch, where the driver decides which one to take. The driver could take either one. What is the solution? Station robbers along both sides of the branch, and wait to see which one the driver chooses. more

Last week, millions of infected devices directed Internet traffic to DNS service provider Dyn, resulting in a Distributed Denial of Service (DDoS) attack that took down major websites including Twitter, Amazon, Netflix, and more. In a recent blog post, security expert Bruce Schneier argued that "someone has been probing the defences of the companies that run critical pieces of the Internet". This attack seems to be part of that trend. This disruption begs the question: Can we trust the Internet? more

Thoughts on the Best Western Compromise

The Sunday Herald reported on Sunday that Best Western was struck by a trojan attack that lead to the possible compromise of about 8 million victims. There is some debate as to the extent of the breach and not a small amount of rumor going around. I'm not entirely disposed to trust corporate press releases for the facts, nor am I going to blindly accept claims of security researchers whose first call is to the PR team when discovering a problem. That said, here is what seems to be the agreed upon facts... more

It's very widely used - OS X and Windows desktops typically use it by default, and most servers should have it running. more

How To Build A Cybernuke

The Internet infrastructure has been having a bad month. Not as bad as, say, the world's aviation infrastructure, but bad enough. First, Chinese Internet censorship leaked out to a few massively unlucky users of the I root server. Then China Telecom failed to filter someone who leaked thousands of hijacked routes to other people's networks through them, probably by accident. And then, inexplicably, Forbes went where no one had gone before... more
