Why Would You Want to Attend a Classroom Workshop?

One of my regular subscribers wondered whether it makes sense to attend a live workshop (like the one we’re running in Miami in a few weeks) instead of listening to my webinars:

I am following your blog posts quite regularly, I’ve been a yearly subscriber for more than 3 years now and I’m even trying to attend as many webinars as I can in real time. Is there a real benefit to participate in this classroom event if we are almost aware of all your slide decks and videos?

Absolutely. Here’s what one of the attendees of a recent SDN workshop wrote when asking me whether I would be willing to do an on-site event for his company:

Is it still possible to do phone phreaking? Yes, with Android on LTE

In the 1960s and 70s, technically savvy enthusiasts sought to game telecommunications systems to make free calls, keeping telecom engineers on their toes.That practice, known as phreaking, involved such luminaries as Steve Jobs, Steve Wozniak and John Draper, known as Cap'n Crunch, who used a whistle from a cereal box to meddle with AT&T's long-distance trunk lines.These days, mobile operators have fully embraced the Internet and are increasingly moving voice calls over fast, packet-switched networks, known as Voice over LTE (Long Term Evolution). The advantage is higher-quality voice calls for subscribers and lower costs for operators.To read this article in full or to leave a comment, please click here

Cyber insurers could help drive IoT standards

Cyber insurance premiums could prove a big driver of Internet of Things standards. Machine-to-machine communication has grown up in separate silos for every industry, but as it expands in the coming years as part of the broader Internet of Things wave, standards could save a lot of cost and effort, speakers at a networking conference said Monday.  Having a common approach that works can save IoT vendors from having to reinvent the wheel, said Jim Zerbe, head of IoT product at Neustar, a real-time information services and analytics company. Security is one place that's needed, he said. For a long time, machine-to-machine security has relied on industry-specific technologies and "security through obscurity," resulting in easily hackable systems. Standard, open technologies across industries can attract armies of developers to build strong defenses.To read this article in full or to leave a comment, please click here

Crypto researchers: Time to use something better than 1024-bit encryption

It’s actually possible for entities with vast computing resources – such as the NSA and major national governments - to compromise commonly used Diffie-Hellman key exchange groups, so it’s time for businesses to switch to something else like elliptic curve cryptography, researchers say.“It’s been recommended to move from 1024-bit [encryption] for a long time, and now there are very concrete risks of not doing that,” says Nadia Heninger, an assistant professor of computer and information science at the University of Pennsylvania who is an author of a paper titled “Imperfect Forward Secrecy: How Diffie-Hellman Fails in Practice”.To read this article in full or to leave a comment, please click here

DEF CON drink-off — for science!

The DEF CON hacking conference is a mixture of techies and drinkers. I propose we exploit this for science. Specifically, we should take a look at vodka. Vodka is just ethanol and water with all taste removed by distillation and filtering. We can answer two important questions.

  1. Poorly made, cheap vodka lets too much of the (bad) flavor through. Can this be improved by running it through a filter? (Such as a cheap Brita water filter).
  2. Well-made vodka should be indistinguishable from each other. Can people really taste the difference? Or are they influenced by brands?

We need to science the shit out of these questions with a double-blind taste test. DEF CON is a perfect venue for getting a statistically relevant number of samples. We should setup a table in a high-traffic area. We'll ask passersby to taste a flight of several vodkas and to rate them.

I suggest the following as the set of vodkas to test.

1. Smirnoff, by far the market leading vodka in America, a "mid-shelf" vodka at $22 for a 1.75 liter bottle.
2. Grey Goose, the third most popular vodka in America, a "top-shelf" vodka for $58 a 1.75 liter bottle.

Tricky new malware replaces your entire browser with a dangerous Chrome lookalike

Security researchers have discovered a fiendish form of browser malware that stands in for your copy of Google Chrome and hopes you won’t notice the difference.As reported by PCRisk, the “eFast Browser” works by installing and running itself in place of Chrome. It’s based on Google’s Chromium open-source software, so it maintains the look and feel of Chrome at first glance, but its behavior is much worse.First, makes itself the default and takes over several system file associations, including HTML, JPG, PDF, and GIF, according to MalwareBytes. It also hijacks URL associations such as HTTP, HTTPS, and MAILTO, and replaces any Chrome desktop website shortcuts with its own versions. Essentially, eFast Browser makes sure to open itself at any opportunity.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Robots that make mistakes may be more useful, study says

Robots will have to be flawed if they are to create successful working relationships with humans, new research has found."Judgmental mistakes, wrong assumptions, expressing tiredness or boredom, or getting overexcited," will help humans "understand, relate to and interact" with robots more easily, Mriganka Biswas of the University of Lincoln in Britain says in an article on the university's website.Biswas has been conducting a study for a PhD on how humans interact with robots. Supporting caregivers Robots are increasingly being used to support caregivers, the article says.To read this article in full or to leave a comment, please click here

Target’s newest security problem: Pranksters taking over PA to blast X-rated audio

Back in September, Brian Krebs reported on a confidential Verizon security assessment of Target’s network done shortly after the company was breached in 2013; Verizon consultants found Target was using weak or default passwords, had failed to deploy critical security patches, were running outdated services and other basic security problems. Target is having trouble again, but this time it’s with pranksters “exploiting holes” in Target’s PA system. It could have been done as an early Halloween prank, except this wasn’t the first time X-rated audio has blasted from a Target store’s PA system.To read this article in full or to leave a comment, please click here

Privacy watchdogs give EU, US three months to negotiate new Safe Harbor deal

European data protection authorities have given the European Commission and national governments three months to come up with an alternative to the Safe Harbor agreement swept away two weeks ago by a ruling of the Court of Justice of the European Union.But any new agreement must protect the personal data of European citizens from massive and indiscriminate surveillance, which is incompatible with EU law, the data protection authorities making up the Article 29 Working Party said late Friday.Since the CJEU ruled on Oct. 6 that the Safe Harbor agreement between the Commission and U.S. authorities did not offer necessary legal guarantees, businesses that relied on it for the transfer of their customers' or employees' private personal information from the EU to the U.S. have been doing so in something of a legal vacuum.To read this article in full or to leave a comment, please click here

Segment: Rebuilding Our Infrastructure with Docker, ECS, and Terraform

This is a guest repost from Calvin French-Owen, CTO/Co-Founder of Segment. 

In Segment’s early days, our infrastructure was pretty hacked together. We provisioned instances through the AWS UI, had a graveyard of unused AMIs, and configuration was implemented three different ways.

As the business started taking off, we grew the size of the eng team and the complexity of our architecture. But working with production was still limited to a handful of folks who knew the arcane gotchas. We’d been improving the process incrementally, but we needed to give our infrastructure a deeper overhaul to keep moving quickly.

So a few months ago, we sat down and asked ourselves: “What would an infrastructure setup look like if we designed it today?”

Over the course of 10 weeks, we completely re-worked our infrastructure. We retired nearly every single instance and old config, moved our services to run in Docker containers, and switched over to use fresh AWS accounts.

We spent a lot of time thinking about how we could make a production setup that’s auditable, simple, and easy to use–while still allowing for the flexibility to scale and grow.

Here’s our solution.

China reportedly tries to hack U.S. businesses the day after agreeing not to

Chinese hackers have gone after seven U.S. tech and pharmaceutical companies since the presidents of both countries agreed not to knowingly carry out corporate espionage, according to security firm CrowdStrike.The company says in a blog post that it has identified a known hacking group in China as intruding into the seven U.S. companies starting the day after Presidents Xi and Obama announced the pact.“It is important to note that this is not an exhaustive list of all the intrusions from Chinese-government affiliated actors we have detected during this time period; it is limited only to commercial entities that fit squarely within the hacking prohibitions covered under the Cyber agreement,” says CrowStrike CTO Dmitri Alperovitch.To read this article in full or to leave a comment, please click here

What Happens to RSA?

While last week’s Dell/EMC merger was certainly a blockbuster, nothing specific was mentioned about future plans for RSA Security.  Michael Dell did say that there were a “number of discussions about security” during the negotiations but apparently, no concrete plans.  Infosec reporters have lobbed phone calls into Round Rock Texas as well as Bedford and Hopkinton, MA looking for more details but Dell and EMC officials haven’t responded.Based upon a week of vague retorts, it’s safe to assume that there is no master plan for RSA at this time.  While we in the cybersecurity world have a nostalgic bond with RSA, it really is small potatoes as part of this mega-deal in the IT space.  Nevertheless, RSA is marquis $1b+ brand named company in the red hot cybersecurity space so there is certainly value to be had.To read this article in full or to leave a comment, please click here

Can You Answer Correctly? BGP Dual-omed With Different As-Path

R23 is configured with maximum-paths 2 and, as you can see, is in the dual-homed topology. All of the attributes are 100% identical with the exception of what you see listed in the picture below. R23 has 2 paths listed in its BGP table for all prefixes being advertised from R15 yet, only installs 1 into its RIB, why does this happen? In addition, what command can I use to fix my problem.

I know the answer but, do you? Leave your answer in the comments!
