Well, it was only a matter of time before what happened last Friday happened. I’m talking about the Distributed Denial of Service (DDoS) incident on server farms of a key internet firm, Dyn, that repeatedly disrupted access to major websites and online services including Twitter, Netflix,GitHub, and PayPal across the U.S. and Europe last Friday. The White House called the disruption malicious and hacker groups have claimed responsibility, though their assertion is not yet verified.
The event involved multiple denial-of-service (DoS) attacks targeting systems operated by Domain Name System (DNS) provider, Dyn, that rendered major internet platforms and services unavailable to large swaths of North America and Europe.
“The complexity of the attacks is what is making it so difficult for us,” said Kyle York, Dyn’s chief strategy officer. “What they are actually doing is moving around the world with each attack.”
As a DNS provider, Dyn provides to end-users the service of mapping an Internet domain name—when, for instance, entered into a web browser—to its corresponding IP address. The DDoS attack involved tens of millions of DNS lookup requests from a large number of IP addresses. The activities are believed to involve a botnet coordinated through a large number of IoT devices that had been infected with the Mirai malware.
Did IoT DDoS Take Down the Internet?
Organizations claiming responsibility said they organized networks of connected “zombie” computers (botnets) that threw a staggering 1.2 terabits per second of data at the Dyn-managed servers.
A denial-of-service (DoS) attack is a cyber-attack where the perpetrator seeks to make a machine or network resource unavailable to its intended users, such as to temporarily or indefinitely interrupt or suspend services of a host connected to the Internet. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled.
A distributed denial-of-service (DDoS) is a cyber-attack where the perpetrator uses more than one, often thousands, of unique IP addresses. The scale of DDoS attacks has continued to rise over recent years, as witnessed by the Dyn attack.
According to Dyn, a distributed denial-of-service (DDoS) attack began at 7:00 a.m. and was resolved by 9:20 a.m. A second attack was reported at 11:52 a.m. and Internet users began reporting difficulties accessing websites. A third attack began in the afternoon, after 4:00 p.m. At 6:11 p.m., Dyn reported that they had resolved the issue.
The US Department of Homeland Security is investigating the attacks. No group claimed responsibility during or in the immediate aftermath of the attack. Dyn’s chief strategist said in an interview that the assaults on the company’s servers were very complex and unlike common, everyday DDoS attacks.
Dyn disclosed that the attack was a botnet coordinated through a large number of IoT devices, including cameras, home routers, and baby monitors that had been infected with Mirai malware. The attribution of the attack to the Mirai botnet had been previously reported by BackConnect, an Internet security firm. Dyn stated that they were receiving malicious requests from tens of millions of IP addresses. Mirai is designed to brute-force the security on an IoT device, allowing it to be controlled remotely. Cybersecurity investigator Brian Krebs noted that the source code for Mirai had been released onto the Internet as open-source earlier in October.
As of today, October 27, 2016, President Obama indicated that investigators still had no idea who carried out the cyber-attack.
For the past several years we all have heard the non-stop hype from a number of different sources that the Internet of Things (IoT) is the thing that will change everything and improve our lives in ways that are still unimaginable to us. That may be true, but relatively little attention is paid to the converse – what are some of the not so great things that could result from IoT? This darker side of IoT, of course, includes security, but how about data handling, infrastructure, privacy, and the inevitable question of who actually owns the data generated from and for IoT. All of these issues are problems now and will only continue to grow unless and until they are adequately addressed.
This week I’ll cover IoT data handling and data infrastructure, both critical if the IoT is to proliferate as many vendors hope and hype. (more…)
For the past few years we all have heard a non-stop proclamation from a number of different sources that the Internet of Things (IoT) is the thing that will change everything and improve our lives in ways that are still unimaginable to us. That may be true, but relatively little attention is paid to the other side of the coin – what are some of the not so great things that could result from IoT? This darker side of IoT, of course, includes security, but how about data handling, infrastructure, privacy, and the inevitability of IoT companies going out of business. All of these issues are problems now and will only continue to escalate unless and until adequately addressed.
Believe me, I’m not alone with these concerns.
This time around I’ll cover IoT privacy and company survival. Next week I’ll cover IoT data handling and infrastructure. (more…)
A couple of days ago, the internet of things (IoT) world was rocked with the announcement that the UK’s semiconductor and software design giant, ARM, was being purchased by Japan’s SoftBank in a cash deal for some $32 billion.
In the official acquisition statement, SoftBank says it intends to:
What a difference a few days make. Last week I was in Denver teaching math to middle schoolers and this week I was in Boston with about 4,000 others attending PTC’s LiveWorx 16. The spotlight at the conference shone on the Internet of Things (IoT) and PTC’s commitment to it.
So, you think that the Internet of Things (IoT) thing is still just a fad? Based on my experience at PTC’s LiveWorx 16 in Boston this week, IoT is becoming an increasingly big part of the future – not only for PTC, but for all of us.
Still not convinced? Just the attendance figures alone from this year over the past couple might help convince you – LiveWorx 2014 (~350 attendees); LiveWorx 2015 (~2,300 attendees); LiveWorx 16 (~4,000 attendees). Attendance numbers don’t lie and that shows the growing interest in IoT. (more…)
This week PTC received the IoT Innovation Vendor of the Year Award from marketing analytics and consulting firm Compass Intelligence at the 2016 International Consumer Electronics Show (CES) in Las Vegas, Nevada. The Compass Intelligence Annual Awards recognize the best mobile computing, wireless data communications, Internet of Things, and eco-friendly products and services offered in the market during the past year.
The IoT Innovation Vendor of the Year Award is part of the A-List in M2M/IoT awards category and is voted on by more than 60 industry-leading press and analysts based upon a range of criteria, including vision, strategy, leadership, and financial success.
In the view of the award presenting organization PTC has become a leading provider of technology that enables its customers to realize the value inherent in the Internet of Things. As well, in their opinion, PTC’s CEO, Jim Heppelmann, has become a major thought leader, having coauthored two seminal HBR articles that describe the implications of the IoT and offer companies a blueprint to get started on their own IoT journeys.
As part of its ongoing acquisition quest, earlier this week PTC announced that it had signed an agreement to acquire the Vuforia business from Qualcomm Connected Experiences for $65 million. Vuforia is a widely adopted augmented reality (AR) technology platform, that PTC is betting will enrich its technology portfolio and further foster its strategy to provide technologies that blend the digital and physical worlds. In other words, the next phase of the Internet of Things (IoT).
Under terms of the agreement, PTC will acquire the Vuforia business, including its developers ecosystem. PTC is committed to continued investment in the Vuforia platform and to the ongoing support and growth of the Vuforia ecosystem, but why wouldn’t it? The deal is expected to close later in 2015.
It was first reported last month that Qualcomm was soliciting bids for Vuforia as part of its effort to cut costs and focus on its key mobile business. The surprise was that PTC was the ultimate suitor for the company and its technology.
Vuforia is a mobile vision platform that enables apps to “see” and connect the physical world with digital experiences that demand attention and drive engagement. Vuforia is supported by a global ecosystem of developers, and has powered more than 20,000 apps with more than 200 million app downloads and installs worldwide.
Vuforia’s technology lets people use their smartphone or tablet to bring advertisements, toys, and other real-world objects to life. The effort has attracted a notable base of developers, but let’s face it, augmented reality remains more of a novelty than a big business. Obviously, PTC is out to change that. (more…)
ANSYS, a major provider of engineering simulation (CAE) software, announced that it has acquired substantially all the assets of Delcross Technologies, a developer of computational electromagnetic simulation and radio frequency system analysis software.
The acquisition is intended to let ANSYS users to understand how antennas interact within their operating environments and how this behavior affects the system’s overall ability to transmit and receive data without interference. As usual, and not surprisingly, terms of the deal, which closed earlier this week, were not disclosed.
So, what does this really signify? Simulating not just large-scale antenna systems, such as those found in giant aerospace projects (which will surely go on after the acquisition), but on a much, much smaller scale for Internet of Things (IoT) projects.
Although it’s almost a year old, below is a video presentation (click on the image) from Delcross Technologies for modeling installed performance of antennas on electrically large platforms, such as aircraft and automobiles.
With all of the buzz that the Internet of Things (IoT) has generated, a number of our readers have asked if there was anything available for experimenters who may have interest, but not a lot of money to spend on exploring the technology. Until recently, the answer would have been, “No.” However, that all changed this month with the availability of the ARM® mbed™ IoT Starter Kit-Ethernet Edition from ARM Ltd.
In the 1980s British computer manufacturer Acorn Computers first developed the Acorn RISC Machine (ARM) architecture for its personal computers.
A reduced instruction set computing (RISC)-based computer design approach with ARM processors require significantly fewer transistors than typical complex instruction set computing (CISC) x86 processors in most personal computers. This approach reduces costs, heat and power use. Such reductions are desirable traits for light, portable, battery-powered devices and other embedded systems. A simpler design facilitates more efficient multi-core CPUs and higher core counts at lower cost, providing improved energy efficiency for servers.
ARM Holdings develops the instruction set and architecture for ARM-based products, but does not actually manufacture products itself.
ARM core processors are used in a wide range of products including the Microsoft Surface tablet, Apple’s iPad, iPhone, and iPod, ASUS tablets, Canon PowerShot digital cameras, and Nintendo DS handheld game consoles. In a word, ARM cores are everywhere.
About a month ago I spent a few days in Boston at PTC’s LiveWorx 2015 event. It was an eye opener for me and a brief look into the future of PTC with its growing emphasis and dependence on the Internet of Things (IoT).
Beyond the technologies and business strategies presented, what struck me was the relatively young crowd attending with relatively young PTC PR people pushing the IoT platform. Sold out with over 2,300 attendees (up from ~350 in 2014), the draw was similar or maybe more than this year’s PTC Live Global user event. Although Creo and Windchill were certainly present at LiveWorx, they took a back seat to IoT offerings, such as ThingWorx, Axeda, and others.
So what does IoT really mean? I don’t know either because it’s evolving so rapidly and all participating vendors define it so that it accommodates what they offer best. In other words, until standards are established, the definition continues to evolve. I will admit, however, that PTC currently has a leg up on virtually all of the competition for IoT in its traditional design, engineering, and manufacturing space.
A standard definition is in the works, however, and IoT generally refers to uniquely identifiable objects and their virtual representations in an Internet-like structure. The term Internet of Things was proposed by Kevin Ashton in 1999, although the concept has been discussed since 1991, so it’s not exactly brand new.
According to PTC, the Internet of Things has the potential to create trillions of dollars of new economic value in the coming decade. To capture this value, manufacturers will rely on new applications that enable the creation of smart, connected products, thus PTC’s interest and commitment, as shown in the brief video below.
