golang up and running on CentOS7

I’ve decided recently to get serious about learning golang.  I’ve had a great time playing around with other peoples code (Docker and Kubernetes namely) and it’s time for me to learn the language so I can contribute more than bash scripts.  For better of for worse, I’ve decided to start coding on a CentOS box.  I have a couple of reasons for doing this…

-Its the Linux distro I’m most familiar with currently
-I need to get better at working in Linux.  More stick time on straight CLI can’t hurt.  I feel like jumping into a full blown IDE might be a bit premature for me and possibly allow me to miss some of the basics as well.
-I plan to run the code on Linux servers (I think…?)

Disclaimer: Im just getting started in golang.  If something I suggest below is wrong, please tell me!  Still learning here

Note: I really struggle with the language called ‘go’.  So Im trying to call it golang everywhere I can.  It can seem like a bit much at times…

So let’s get started.  The goal of this post is to end Continue reading

Cell service at US airports varies from first class to middle-seat coach

Need something to watch on a flight? You can download an episode of your favorite show in less than a minute and a half on Verizon Wireless at Atlanta’s airport—or spend 13 hours doing the same over T-Mobile USA at Los Angeles International.The comparison of 45-minute HD video downloads illustrates the wide variation in cellular service at U.S. airports, which RootMetrics laid out in a report for the first half of 2015 that’s being issued Thursday. Atlanta’s Hartsfield-Jackson is the best place to go mobile and Verizon covers airports best overall, but just like security lines and de-icing delays, it all depends.RootMetrics tested mobile data connections using all four major carriers at the 50 busiest airports in the country, checking not just for speed but for how long it took to get on and how well the connection stayed up. The tests took place in well-used places like ticketing, baggage claim and terminal gates. RootMetrics didn’t test voice service or Wi-Fi networks.To read this article in full or to leave a comment, please click here

GNS3 Version 1.3: What’s new for Open-Source Routers

In 2014, the GNS3 development team launched a successful Kickstarter crowdfunding campaign to support development of a major new release, version 1.0, which was released in October that same year. I was happy to support the Kickstarter campaign and now I am finally getting around to taking a look at the new version of GNS3.

GNS3-v1x-064

The last time I used the GNS3 network simulator, it was at version 0.8.7. After producing version GNS3 1.0, the GNS3 development team has been updating it frequently. GNS3 is now at version 1.3.7.

In this post, I will look at the new version 1.3.7 of GNS3 and evaluate how it works with emulated routers and hosts running open-source software.

What’s new in GNS3 1.x

Below, I describe the new GNS3 1.x features in two sections. The first section summarizes new GNS3 features that are relevant to all users of GNS3, including those who will use GNS3 to emulate networks consisting of routers and hosts running open-source software. The second section summarizes new features relevant only those who are running commercial router images in GNS3.

Nigerian scammers buy exploit kits to defraud Asian businesses

A small group of Nigerian scammers is using more sophisticated methods to defraud mostly Asian businesses, including buying exploit kits and malware from experienced coders, according to a new report from FireEye.The security company said the group performs deep reconnaissance of its potential victims, jumping inside financial transactions in order to try to divert payments to their own accounts.The schemes are much more complex than so-called 419 or advance fee fraud scams, where random victims are induced to send funds in order to get a non-existent but much larger payoff.To read this article in full or to leave a comment, please click here

Microsoft follows Google to crack down on revenge porn

Microsoft will make it easier for people to request the removal of links to intimate images or videos from the company's Bing search engine if such content was posted online without their consent. This move comes in response to an increasingly prevalent phenomenon dubbed "revenge porn," where jilted former partners or extortionists upload sexually explicit content depicting the victims in an embarrassing light. "Unfortunately, revenge porn is on the rise across the globe," said Jacqueline Beauchere, Microsoft's chief online safety officer, in a blog post. "It can damage nearly every aspect of a victim's life: relationships, career, social activities. In the most severe and tragic cases, it has even led to suicide."To read this article in full or to leave a comment, please click here

Startup launches big data-as-a-service

For many enterprises, big data is hard and slow. Procurement and deployment of data infrastructure can be both expensive and difficult to scale at the pace that data volumes can grow. A startup founded by former Netezza executives says that the answer to these data engineering woes is the cloud. The startup, Cazena, came out of stealth today after two years of development with an enterprise big data-as-a-service offering intended to simplify and automate securely moving and optimizing big data processing in the cloud. It's a managed service platform that founder and CEO Prat Moghe — who served as senior vice president of strategy, products and marketing at Netezza — says addresses the security and complexity challenges that have kept many enterprises from migrating their big data workloads to the cloud.To read this article in full or to leave a comment, please click here

How to check if you’ve been attacked by Hacking Team intrusion malware

Hacking Team malware has been attacking computers and smartphones --- and you may be infected without knowing it. Here's how to find out if you're infected. Hacking Team is an Italian-based company that sells surveillance and intrusion software to government agencies and law enforcement groups across the world. Earlier this month its systems were broken into and the Hacking Team's intrusion software was released to the world. That means that hackers could grab hold of it for their own purposes and attack computers and smartphone. Since then, Microsoft has released a patch for Windows designed to close a security hole that could be exploited by Hacking Team Software. Adobe has released a patch for Flash Player, which is vulnerable as well.To read this article in full or to leave a comment, please click here

US court says ‘pocket-dialed’ calls are not private

A federal appeals court in Ohio has ruled that a person who accidentally “pocket dials” someone shouldn’t expect any overheard conversation to be considered private.The case involves the chairman of the Airport Board in Kenton, Kentucky, which oversees the Cincinnati/Northern Kentucky International Airport. The chairman, James Huff, was on a business trip in Italy with his wife and a colleague when he accidentally pocket-dialed the secretary of the airport’s CEO back in the U.S.The secretary, Carol Spaw, said “hello” a few times and soon figured out the call wasn’t meant for her. But she overheard Huff and his colleague talking about personnel matters, including the possibility that the airport’s CEO—Spaw’s boss—might be replaced. The inadvertent call continued after Huff got back to his hotel room with his wife.To read this article in full or to leave a comment, please click here

Qualcomm plans cuts, may spin off assets

Qualcomm will cut costs by about $1.4 billion per year and study the possible sale of assets as part of a company realignment.The mobile technology juggernaut is also shaking up its board of directors as part of an agreement with investment company Jana Partners. Jana, which owns a chunk of Qualcomm’s stock, has pressured the company to spin off its chip division from its patent licensing business.The realignment was announced as Qualcomm reported its profit fell by nearly half in the April-to-June quarter on revenue that declined by 14 percent from a year earlier.“The changes we are announcing today are designed to enable us to right-size our cost structure and reposition Qualcomm for improved financial and operating performance,” CEO Steve Mollenkopf said in a statement.To read this article in full or to leave a comment, please click here

Infosec’s inability to quantify risk

Infosec isn't a real profession. Among the things missing is proper "risk analysis". Instead of quantifying risk, we treat it as an absolute. Risk is binary, either there is risk or there isn't. We respond to risk emotionally rather than rationally, claiming all risk needs to be removed. This is why nobody listens to us. Business leaders quantify and prioritize risk, but we don't, so our useless advice is ignored.

An example of this is the car hacking stunt by Charlie Miller and Chris Valasek, where they turned off the engine at freeway speeds. This has lead to an outcry of criticism in our community from people who haven't quantified the risk. Any rational measure of the risk of that stunt is that it's pretty small -- while the benefits are very large.

In college, I owned a poorly maintained VW bug that would occasionally lose power on the freeway, such as from an electrical connection falling off from vibration. I caused more risk by not maintaining my car than these security researchers did.

Indeed, cars losing power on the freeway is a rather common occurrence. We often see cars on the side of the road. Few accidents are caused Continue reading

How to configure a cheap, secure RAID backup system

We usually store our photos, documents, and more on a single hard disk—or, increasingly these days, a solid state drive (SSD)—but there’s always the nagging worry that the disk will fail, taking all your work and memories with it. Backing up using Time Machine, Super Duper!, or CrashPlan, say, is a good way of reducing this risk, but there is another: RAID. RAID can be incredibly complicated, but it’s extremely worthwhile—one of the things it can do is to mirror the contents of one disk completely to another, all the time. While cloning your hard disk using Super Duper!, for example, is something that might happen once a day, with a RAID system, every bit of data that’s written to one disk is simultaneously written to the second, so that if one drive fails, you have a perfect copy of everything it contained on the second. (And optionally, if you replace the failed drive, everything will be mirrored back across to it automatically.)To read this article in full or to leave a comment, please click here
