Tech’s ticking time bombs: The components you might (and might not) expect to wear out

Frequent failureImage by ENIAC used over 17,000 vacuum tubes. TexasDex/Wikipedia.The early computers of the vacuum-tube age were marvels of engineering for their time. Today, we can simultaneously appreciate the advances these computers represented, making previously unthinkable computational work possible, and chuckle at what to us seems like their ludicrous size and painfully slow processing speeds.To read this article in full or to leave a comment, please click here

Rearchitecting L3-Only Networks

One of the responses I got on my “What is Layer-2” post was

Ivan, are you saying to use L3 switches everywhere with /31 on the switch ports and the servers/workstation?

While that solution would work (and I know a few people who are using it with reasonable success), it’s nothing more than creative use of existing routing paradigms; we need something better.

Google makes mobile websites more app-like with Chrome push notifications

Google has taken a big step in its efforts to make mobile websites act more like native applications on Android smartphones, by adding notifications to its browser.One of the most convincing arguments for building an application instead of a website has been the ability to send notifications to users. Google is hoping to narrow that advantage by adding the feature to version 42 of its Chrome browser for Android.As a result, Android developers no longer have to decide between the engagement potential of a native app and the reach of a mobile website, Google said in a blog post on Monday.To read this article in full or to leave a comment, please click here

To control your phone, just keep tapping it

If you’re tired of touching that touchscreen, try hitting your phone and making some noise.Researchers in South Korea have developed a sound-based method of controlling smartphones, and connected appliances, by tapping them.Graduate students from Seoul National University of Science and Technology are demonstrating an Android app called Sound Tap at the 2015 Computer-Human Interaction Conference (CHI) in Seoul this week.Sound Tap can be used to control a smartphone by tapping its rear surface with a finger once or twice, or by lightly striking the phone itself against various surfaces in the environment. Since the taps create unique frequencies, they can be used to trigger different functions on the phone, such as calling up browsers, photo galleries or music players.To read this article in full or to leave a comment, please click here

HOL Head-of-line blocking

How does Internet work - We know what is networking

Head-of-line blocking (HOL blocking) in networking is a performance issue that occurs when a bunch of packets is blocked by the first packet in line. It can happen specially in input buffered network switches where out-of-order delivery of packets can occur. A switch can be composed of input buffered ports, output buffered ports and switch fabric. When first-in first-out input buffers are used, only the first received packet is prepared to be forwarded. All packets received afterwards are not forwarded if the first one cannot be forwarded. That is basically what HOL blocking really is. If there’s no HOL blocking

Bedep’s DGA: Trading Foreign Exchange for Malware Domains

As initially researched by Trend Micro [1] [2], Zscaler [1] [2], Cyphort, and Malware don’t need Coffee, the Bedep malware family focuses on ad / click fraud and the downloading of additional malware. ASERT’s first sample dates from September 22, 2014, which is in line with when Trend Micro started seeing it in their telemetry. In early 2015, the family got some more attention when it was being observed as the malware payload for some instances of the Angler exploit kit, leveraging the Adobe Flash Player exploit (CVE-2015-0311) which at the time was a 0day. It was also observed that this newer version was using a domain generation algorithm (DGA) to generate its command and control (C2) domain names.

This post provides some additional notes on the DGA including a proof of concept Python implementation, a look at the two most recent sets of DGA generated domains, and concludes with some sinkhole data.

Samples

The following Bedep samples were used for this research:

• MD5 e5e72baff4fab6ea6a1fcac467dc4351
• MD5 1b84a502034f7422e40944b1a3d71f29

The former was originally sourced from KernelMode.

Algorithm

I’ve posted a proof of concept (read: works for me) Python implementation of the DGA to ASERT’s Github.

Intel and Ericsson Deepen Ties in Managed Security Services

Another partnership between the two giants, this time targeting telco-managed security.

Using the POX SDN controller

In this tutorial, we will demonstrate basic software-defined networking (SDN) concepts using the POX SDN controller, POX components, and the Mininet network simulator.

We will show how to use the POX SDN controller to create software defined networks that can be used to forward packets from one host to another and create flows on the SDN switches in the network. We will use the Mininet network simulator to create the network of emulated SDN switches and hosts that will be controlled by the POX SDN controller.

Pushdo spamming botnet gains strength again

Computers in more than 50 countries are infected with a new version of Pushdo, a spamming botnet that has been around since 2007 and survived several attempts to shut it down.At one time, Pushdo-infected computers sent as many as 7.7 billion spam messages per day. Security analysts have tried to kill it four times by commandeering its infrastructure, but a new version of the malware has emerged once again, with high concentrations of infections in countries such as India, Indonesia, Turkey and Vietnam.“Pushdo was very successful in what it did, so coming up with various revisions or versions of it makes a lot of sense for the bad guys,” said Mike Buratowski, vice president of cybersecurity services at Fidelis Cybersecurity, based in Austin, Texas.To read this article in full or to leave a comment, please click here

Great customer experience is an elusive goal

Every company says it wants to provide a top-notch customer experience; how many actually do is another matter.To wit: Although improving the customer experience is a strategic priority at a full 73 percent of businesses surveyed for a new Forrester Research report released Monday, only 1 percent of companies currently deliver an excellent experience, the study found.That’s a problem, Forrester says, because customer experience (sometimes called CX) has become a more strategic imperative than ever.“Growth is now the top priority for business leaders, and to achieve that you have to improve customer experience,” said Kyle McNabb, a vice president of research strategy with Forrester. “Traditionally we’ve all worked toward metrics like ROI, but now the metric is impact on experience.”To read this article in full or to leave a comment, please click here

IBM sales dip 12 percent despite lift from new mainframe

IBM reported a 12 percent drop in revenue for the last quarter despite a big boost from its new z13 mainframe, which went on sale last month.Revenue for the quarter ended March 31 was $19.6 billion, with profit down 5 percent to $2.4 billion, IBM announced Monday.Two-thirds of the company’s business comes from overseas, and the strong U.S. dollar weighed on its results. Without the currency impact, and adjusting for businesses that IBM recently sold off, revenue would have been flat from a year ago, CFO Martin Schroeter said on IBM’s earnings call.Like its rival Hewlett-Packard, IBM has been watching its business shrink for several quarters as customers spend less on expensive hardware and IT services and devote more to cloud computing and mobile.To read this article in full or to leave a comment, please click here

VMware prepares its virtualization stack for Docker

VMware may have pioneered enterprise virtualization, but until Monday it had been relatively quiet when it comes to Docker containers, the popular lightweight form of application virtualization.Now it’s addressing the market for Docker with two open source software packages that will allow its customers to more easily deploy containers in their existing VMware infrastructure.The company has released a Linux distribution, called Project Photon, which was designed to run within a VMware virtual machine hypervisor and contains only the barest essentials that an operating system would need for running containers. The company has also released access management software, called Project Lightwave, that gives system administrators a way to control the access to their containers.To read this article in full or to leave a comment, please click here

Are you ready for Google’s ‘Mobilegeddon’ on Tuesday?

Google said in February that it was going to make mobile-friendliness matter more to its search-engine rankings. On Tuesday, it makes good on that commitment—and webmasters who didn’t heed the warning may see a steep drop in traffic.It’s a shift so potentially fraught with peril for those who aren’t ready that it’s being called “Mobilegeddon.” Essentially, Google is expanding its use of mobile-friendliness as a ranking signal when it compiles search results. Sites that are mobile-friendly will be ranked higher in search results; those that aren’t will suffer.To read this article in full or to leave a comment, please click here

VMware just created its first Linux OS, and it’s container-friendly

VMware Monday announced its first operating system, and it’s designed to run containers inside the company’s virtualization management software. In announcing the Linux OS, named Project Photon, VMware is attempting to convince users who are curious about using containers that they can do so while still using the company’s software. + MORE FROM NETWORK WORLD: Will containers kill the virtual machine? + VMware As container technology has gained popularity in recent months there’s been a debate in the cloud computing and virtualization market about whether it is best to run containers on bare metal, meaning without a hypervisor, or in virtual machines. If containers run on bare metal, it could remove the need for VMware’s virtualization software.To read this article in full or to leave a comment, please click here
