Brian Krebs is a popular reporter on the cybersecurity beat. He regularly exposes cybercriminals and their tactics, and consequently is regularly a target of their ire. Last month, he wrote about an online attack-for-hire service that resulted in the arrest of the two proprietors. In the aftermath, his site was taken down by a massive DDoS attack.In many ways, this is nothing new. Distributed denial-of-service attacks are a family of attacks that cause websites and other internet-connected systems to crash by overloading them with traffic. The "distributed" part means that other insecure computers on the internet—sometimes in the millions—are recruited to a botnet to unwittingly participate in the attack. The tactics are decades old; DDoS attacks are perpetrated by lone hackers trying to be annoying, criminals trying to extort money, and governments testing their tactics. There are defenses, and there are companies that offer DDoS mitigation services for hire. Basically, it's a size vs. size game. If the attackers can cobble together a fire hose of data bigger than the defender's capability to cope with, they win. If the defenders can increase their capability in the face of attack, they win. What was new about the Krebs attack was both the massive scale and the particular devices the attackers recruited. Instead of using traditional computers for their botnet, they used CCTV cameras, digital video recorders, home routers, and other embedded computers attached to the internet as part of the Internet of Things. Much has been written about how the IoT is wildly insecure. In fact, the software used to attack Krebs was simple and amateurish. What this attack demonstrates is that the economics of the IoT mean that it will remain insecure unless government steps in to fix the problem. This is a market failure that can't get fixed on its own.

Huawei Technologies, the world’s largest telecommunications equipment supplier, is set to launch its HongMeng operating system (OS) as a potential alternative to Google's Android OS, on August 9 at Huawei's Developer Conference, industry insiders told the Global Times Wednesday. According to media reports, the user experience (UX) design features a brand new ringtone and notification panel, a cleaner interface for the camera, more animation and faster speed. Users can also add widgets and personalize the locked screen. Citing industry experts (most likely of Chinese origin), the Global Times reported that "it is possible for Huawei to build a sustainable smartphone ecosystem on the HongMeng OS and reshape the current market dominated by Android and Apple's iOS", although the new system is primarily designed for industrial automation and applications in the Internet of Things (IoT). "Given the design features of the HongMeng OS, it can be a game changer in IoT-related areas, such as driverless cars and smart homes," Fu Liang, a Beijing-based independent industry analyst, told the Global Times. According to Huawei's website, the HongMeng OS is built with a processing latency of less than 5 milliseconds, which is especially required in circumstances involving IoT applications that often need to transfer large amount of data simultaneously.

Last month, we wrote about Bruce Schneier's warning that certain unknown parties were carefully testing ways to take down the internet. They were doing carefully configured DDoS attacks, testing core internet infrastructure, focusing on key DNS servers. And, of course, we've also been talking about the rise of truly massive DDoS attacks, thanks to poorly secured Internet of Things (IoT) devices, and ancient, unpatched bugs. That all came to a head this morning when large chunks of the internet went down for about two hours, thanks to a massive DDoS attack targeting managed DNS provider Dyn. Most of the down sites are back (I'm still having trouble reaching Twitter), but it was pretty widespread, and lots of big name sites all went down. Just check out this screenshot from Downdetector showing the outages on a bunch of sites:

You'll see not all of them have downtime (and the big ISPs, as always, show lots of complaints about downtimes), but a ton of those sites show a giant spike in downtime for a few hours. So, once again, we'd like to point out that this is as problem that the internet community needs to start solving now. There's been a theoretical threat for a while, but it's no longer so theoretical. Yes, some people point out that this is a difficult thing to deal with. If you're pointing people to websites, even if we were to move to a more distributed system, there are almost always some kinds of chokepoints, and those with malicious intent will always, eventually, target those chokepoints. But there has to be a better way -- because if there isn't, this kind of thing is going to become a lot worse.
