Estonian man gets over 7 years in prison for role in global DNS hijacking botnet

An Estonian man has been sentenced to seven years and three months in prison in the U.S. for his role in a cybercriminal operation that infected over 4 million computers with DNS hijacking malware.Vladimir Tsastsin, 35, from Tartu, Estonia, was one of the key players in a US$14 million click fraud scheme. He is the sixth individual to be sentenced in the case and has received the longest prison sentence. The sentence was handed down Tuesday in U.S. District Court for the Southern District of New York.According to the Department of Justice, between 2007 and 2011, Tsastsin and his co-conspirators set up companies that masqueraded as publisher networks and entered into agreements with advertising brokers to display ads on their properties.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Pure pixie dust from Teridion. It’s like Waze, but for the internet

Every now and then I get a product demo that makes me grin. One where the value of the product is just so obvious that I can't argue. That was the case recently when I met with Teridion and heard about what they're up to.Technically speaking Teridion offers a cloud-optimized routing platform. That is an uber-technical description and doesn't really do the product justice. But how about a description that is easier to understand? Like Waze, but for the internet? Or how about some results—a 20 times internet performance improvement?Teridion offers the Global Cloud Network (GCN) a new approach to content delivery that is both non-caching and secure—and required no hardware or pre-provisioning of servers. GCN is a globally routed overlay network leveraging cloud-optimized routing. Teridion deploys a number of Cloud Virtual Routers across the global data centers of multiple cloud vendors. These routers automatically sense localized traffic issues and route traffic to the best path for optimum speed. The net result is blazing performance.To read this article in full or to leave a comment, please click here

OpenStack then and now

Six years ago in July 2010 OpenStack held its first ever Summit; a group of 75 people, many from Rackspace and NASA, gathered in Austin, Texas to help launch the open source project.This week 7,500 attendees descended on the 14th semi-annual OpenStack Summit, which returned to its hometown since that inaugural event. Things are very different now than they were then.+MORE AT NETWORK WORLD: OpenStack users share challenges, benefits of open source cloud computing | Cool products from OpenStack Austin Summit +To read this article in full or to leave a comment, please click here

Zuckerberg sees ‘better than human’ AI in next 10 years

Mark Zuckerberg expects artificial intelligence will progress to make computers better than humans at basic sensory perception within the next 10 years, and that Facebook will end up knowing a lot more about you than it does now.The prediction is the latest from a top tech CEO to indicate the fast improvement being made in machine learning systems that just a few years ago would have struggled to recognize a dog from a cat.The Facebook CEO was speaking about core things that humans do, such as seeing, hearing and understanding language and was careful to clarify that computers will still have limited abilities elsewhere."That doesn't mean that the computers will be thinking or be generally better, but that is useful for a number of things," he told financial analysts on a conference call on Wednesday.To read this article in full or to leave a comment, please click here

Microsoft is making big data really small using DNA

Microsoft has partnered with a San Francisco-based company to encode information on synthetic DNA to test its potential as a new medium for data storage. Twist Bioscience will provide Microsoft with 10 million DNA strands for the purpose of encoding digital data. In other words, Microsoft is trying to figure out how the same molecules that make up humans' genetic code can be used to encode digital information. While a commercial product is still years away, initial tests have shown that it's possible to encode and recover 100 percent of digital data from synthetic DNA, said Doug Carmean, a Microsoft partner architect, in a statement.Using DNA could allow massive amounts of data to be stored in a tiny physical footprint. Twist claims a gram of DNA could store almost a trillion gigabytes of data.To read this article in full or to leave a comment, please click here

Here’s how slow your laptop’s USB Type C port could be

USB Type C is the intriguing new port that began appearing in laptops, tablets, phones, and other devices well over a year ago, but we had no real way test its throughput performance until now. Thanks to Sandisk’s Extreme 900, we’re finally able to push that tiny reversible port to its limits. To do that I gathered up no fewer than eight laptops equipped with USB Type C ports, and threw in a desktop PCIe card for good measure too.What your USB-C port isn't telling you USB Type C is supposed to be a universal standard, but it’s just universally confusing. A USB Type C port can run at either 5Gbps or 10Gbps and still be labeled USB 3.1 by the laptop maker. USB Type C even technically supports USB 2.0 speeds at a pathetic 480Mbps. So when you see a USB Type C port, the only assumption you can make is that its transfer speeds can vary from as low as 480Mbps to as high as 10Gbps.To read this article in full or to leave a comment, please click here

10 Android apps developers will love

Android apps for app buildersWhen it comes to tablet apps, iPad vs. Android comparisons spark spirited debate. In the area of apps for developers, the Android tablet apps are more often free and less polished. On the other hand, there are plenty of Android tablet apps that will help developers in one way or another. While Android takes a lot of flack for “fragmentation,” in many ways it is now less fragmented than iOS from the viewpoint of a developer. It’s straightforward to create a single Android app that will work properly on a large range of devices, measured in operating system level, CPU power, available memory, and device size. On iOS, developers often find themselves writing separate iPhone and iPad apps in order to optimize both.To read this article in full or to leave a comment, please click here

How to protect digital identity in an IoT world

Identity protectionImage by ThinkstockThe IoT security battle is lost if you’re uncertain that the person or thing on the other end of an online transaction is actually who or what it claims to be. Most IoT attacks occur when malicious actors are able to replace an authentic sensor with a compromised device, or when unauthorized remote access is gained and transmits a false signal to a device. To prevent these kinds of attacks, digital identity must establish effective online trust for all connected devices and people in an IoT interconnected ecosystem. This kind of online trust is achieved by implementing a comprehensive approach to digital identity and access management.To read this article in full or to leave a comment, please click here

Paying ransomware is what ills some hospitals

Ransomware has become a major threat to the U.S. healthcare industry this year. The high-profile attacks that involved Hollywood Presbyterian Hospital in Los Angeles, MedStar Health in Washington, D.C., and other healthcare systems are just the tip of the iceberg. Over half of hospitals surveyed recently by HIMSS Analytics and Healthcare IT News said they had been hit by ransomware attacks in the past year. Another 25 percent were unsure whether such attacks had occurred. To read this article in full or to leave a comment, please click here

Announcing Support for HTTP/2 Server Push

Last November, we rolled out HTTP/2 support for all our customers. At the time, HTTP/2 was not in wide use, but more than 88k of the Alexa 2 million websites are now HTTP/2-enabled. Today, more than 70% of sites that use HTTP/2 are served via CloudFlare.

Incremental Improvements On SPDY

HTTP/2’s main benefit is multiplexing, which allows multiple HTTP requests to share a single TCP connection. This has a huge impact on performance compared to HTTP/1.1, but it’s nothing new—SPDY has been multiplexing TCP connections since at least 2012.

Some of the most important aspects of HTTP/2 have yet to be implemented by major web servers or edge networks. The real promise of HTTP/2 comes from brand new features like Header Compression and Server Push. Since February, we’ve been quietly testing and deploying HTTP/2 Header Compression, which resulted in an average 30% reduction in header size for all of our clients using HTTP/2. That's awesome. However, the real opportunity for a quantum leap in web performance comes from Server Push.

Pushing Ahead

Today, we’re happy to announce HTTP/2 Server Push support for all of our customers. Server Push enables websites and Continue reading

IDG Contributor Network: Government worst of all industries in cybersecurity, says report

“Government, we have a problem”—to paraphrase the crew of the 1970 moon flight reporting back on Apollo 13’s technical fault. But it sounds about right to describe, in one line, the somewhat frightening state of U.S. government infrastructure—including that of NASA, which is the worst of the federal agencies—exposed recently in a report.Network infrastructure weaknesses and vulnerabilities abound, according to SecurityScorecard.The tip of the iceberg appears to be the now-famous 2015 Office of Personnel Management loss of 21 million people’s Social Security numbers and other Personally Identifiable Information (PII).To read this article in full or to leave a comment, please click here
